Warning - heavy object.

Warning - entanglement.

Warning - possible explosion.
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 ATEX directive implications
The booster pump is not designed to meet European ATEX requirements.
1.3 Description
WARNING
Standard booster pumps are not intended for use with hazardous, reactive, flammable and explosive gases. Consult Edwards for advice before you use a booster pump on one of these applications.
The booster pumps are single stage, positive displacement precision engineered machines. You must use the booster pump with a suitable backing or roughing pump. The booster pump is not intended for stand-alone operation. The pump gears provide for quiet operation while maintaining proper impeller timing. The booster pumps are supplied as standard with keyless timing, drive side roller bearings, mechanical vacuum seal, and large oil-level sight-glasses. These features provide for ease of maintenance and improve reliability. The pump identification plate provides specific details about the pump, including: pump type; part number and serial number; and so on. We recommend that you have this information available when you contact Edwards for advice, parts or service. Direct drive booster pumps are supplied with hydrocarbon lubricating oil in the oil reservoirs. Standard bareshaft booster pumps are also supplied with hydrocarbon lubricating oil in the oil reservoirs. Special service (oxygen service) bareshaft booster pumps are specially prepared free of hydrocarbons in the factory and are supplied without oil in the reservoirs. You must use PFPE lubricating oil in special service (oxygen service) pumps.

Introduction

S900-01-880 Issue C

MSeal booster pumps have a mechanical shaft seal on the drive shaft, and labyrinth shaft-seals between the gearbox and the swept volume. Process isolation booster pumps have a mechanical shaft seal on the drive shaft, and mechanical seals between the gearbox and the swept volume.
The booster pump general arrangements are shown in Figures 1 and 2.
1.4 General information

The booster pumps are available in horizontal (H) and vertical (V) configurations. The models of booster pumps are the 607, 615 and 622 and these model numbers denote the pump body lengths: 7.0, 15.0 and 22.0 inches. The booster pumps are available as bareshaft (belt driven) pumps, and as direct drive pumps (with shaft-mounted motors).
The booster pump gear centre distance is 6 inches. The booster pump have normal operation limits from 800 to 3600 r min-1 (r.p.m.). The volumetric pumping rates increase with body length and rotational speed. Pump components in contact with the pumped gases are cast iron and carbon steel.
Refer to Table 1 to determine the operational limits for the booster pumps. The limits are based on compression and pumping speeds for the specific application. Table 1 provides the maximum performance limits of the pumps. The limits, backing pump speed and gas loads determine the cut-in pressure and continuous operation pressure limits.
Edwards can recommend cut-in and operation limits when supplied with chamber size, backing pump and gas load information. The first limit reached during operation is the limiting factor. Control devices such as timers and pressure and temperature switches may be required to properly control the operation of the booster pumps.

1.5 Booster pump models

The booster pumps are available in two versions:
 H model booster pumps have vertical connections and are configured for horizontal gas flow through the pump. ("H" appears in the Item Number of these pumps.)
 V model booster pumps have horizontal connections and are configured for vertical gas flow through the pump. ("V" appears in the Item Number of these pumps.)
The 615 booster pump is available with an optional bypass valve (see Section 1.9) which allows pump operation from atmospheric pressure and reduces pump-down time. The booster pumps can be prepared hydrocarbon free for oxygen service. Variable frequency (speed) drives are available for the pumps.

Introduction

S900-01-880 Issue C
You must never operate the booster pump unless it is installed in a proper vacuum system with adequate guarding to protect people from injury. You must fit safety guards to bareshaft booster pumps before operation. Note that:
 "B" in the pump Item Number specifies that the pump has a bypass valve.  "5H" or "5V" in the pump Item Number specifies that the pump is a process isolation booster pump,
otherwise the pump is an MSeal booster pump.  "HR" or "VR" at the end of the Item Number specifies that the pump is a standard service bareshaft pump
(with hydrocarbon oil), "HR101" or "VR101" at the end of the Item Number specifies that the pump is an oxygen service (hydrocarbon free) bareshaft pump, otherwise the pump is a standard service pump (with hydrocarbon oil).

1.6 Principle of operation
The basic operation of an H (horizontal) booster is shown in Figure 3. Figure 3 - Principle of operation Detail A - Gas (3) enters the pump body through the inlet (1). In the pump body, the upper impeller rotor rotates clockwise, and the lower impeller rotor rotates anticlockwise (counterclockwise).
Detail B - As the impeller rotors rotate, gas (3) is drawn into the volume between the pump body wall and the rotors.

Page 6

Detail C - As the rotors rotate further, gas (3) is trapped between the pump body wall and the rotors, and is transferred towards the outlet (2). The rotors rotate with precise timing to maintain the proper clearances, limiting gas back flow.
Detail D - As the rotors rotate further, the gas (3) is discharged through the pump outlet (2). The pump discharges four volumes for every full rotation of the drive shaft.
Detail E: bypass valve operation (only applicable to pumps with a bypass valve) - The optional integral bypass valve limits the pressure differential across the pump. During pump operation, if the compression creates an excessive pressure differential across the pump, the bypass valve (4) opens, to allow a portion of the compressed gases (5) to flow back towards the inlet side of the pump.

Introduction

S900-01-880 Issue C
1.7 Bareshaft (belt drive) booster pumps
The booster pumps have been designed to withstand loading from standard V-belts, for standard operation from 800 to 3600 r min-1 (r.p.m.). The loads induced into the drive shaft depend on the power applied to the shaft. Edwards specifies a minimum pulley diameter for the drive shaft based on motor power. You must never use a pulley with a smaller diameter than those specified in this manual. Refer to Table 12 for specific details on pulley diameters. Edwards can provide booster pumps and motors sized for most applications.
1.8 Direct drive booster pumps (with shaft-mounted motors)
Direct drive eliminates the tension loads associated with belt drives. The direct drive booster pump consists of a standard booster pump, coupling, motor support, and C-face (NEMA) or D-flange (IEC) motor. Optional variable frequency drives are available from Edwards to improve performance on booster pumps without bypass valves. Consult Edwards for application information. Various voltage, frequency, speed and power motors are available. Large power motors (> 22.37 kW, 30 h.p.) cannot be supported by a motor support alone.
1.9 Integral bypass valve (model 615 pumps only)
Model 615 booster pumps can be supplied with an integral bypass valve for operation from atmospheric pressure. The bypass regulates the amount of compression across the booster pump body. The limiting speed for the bypass booster pump is 3600 r min-1 (r.p.m.). The bypass valve regulates the pressure differential across the booster pump to 7.9 x 103 Pa (79 mbar, 60 Torr). Maximum discharge temperature and maximum temperature rise are the same as for the standard 615 booster pumps. Under some operating conditions, it is not possible to operate the bypass booster pumps continuously because of the heat generated from gas compression. These conditions depend on chamber size and backing pump speeds. Consult Edwards if pump-down exceeds 45 minutes. Refer to Figure 3 detail E for a crosssection view of a bypass booster pump.
1.10 Oxygen and reactive gas service
Edwards can prepare bareshaft booster pumps for hazardous gas duties (where pumped gases could react with the hydrocarbon lubricants in standard pumps). When prepared for hazardous gas duties, the booster pumps will be free of hydrocarbons and must be used with inert lubricating oil which will not react with the hazardous gases pumped.
You must take special care when operating booster pumps on oxygen pumping duties: refer to the "Vacuum pump and vacuum system safety - chemical & industrial systems" publication (Edwards Publication Number P400-40-100).

3.1

Safety
WARNING
Obey the safety instructions listed below and take note of appropriate precautions. If you do not, you can cause injury to people and damage to equipment.

 A suitably trained and supervised technician must install the booster pump. The installation technician must obey all local and national safety requirements.
 Ensure that the installation technician is familiar with the safety procedures which relate to the pump oil and the products processed by the pumping system.
 Consult Edwards publication P400-40-100 (Vacuum pump and vacuum system safety - chemical and industrial systems) before you install and use the booster pump to process hazardous or flammable materials.
 Vent and purge the pumping system before you start installation work.
 Check that all the required components are available and of the correct type before you start work.
 Ensure that debris does not get into the booster pump when you install it.
 Disconnect the other components in the pumping system from the electrical supply so that they cannot be operated accidentally.
 Do not reuse 'O' rings and co-seals.
 Ensure that all electrical cables and purge gas pipelines are safely positioned, secured and routed, so that they do not present a trip hazard.
 Provide adequate access to all pump servicing points and oil-level sight-glasses.
 Leak test the system after installation work is complete and seal any leaks found, to prevent leakage of hazardous substances out of the system and leakage of air into the system.
3.2 System design considerations
Consider the following points when you design the pumping system:
 You must mount the booster pump on a firm, level surface.
 Adequately support vacuum pipelines to prevent the transmission of stress to pipeline joints.
 If necessary, incorporate flexible pipelines in your system pipelines to reduce the transmission of vibration and to prevent loading of the coupling joints. If you use flexible pipelines, you must ensure that you use flexible pipelines which have a maximum pressure rating which is greater than the highest pressure that can be generated in the system.
 Ensure that the design incorporates all appropriate safety precautions if toxic, inflammable or explosive gases or particulates will be pumped. Your design must ensure that:
 Where a flammable gas is pumped, the concentrations of the gas in air must be less than 25% of its LEL (Lower Explosive Limit) concentrations.
 Where a toxic gas is pumped, the concentration of the gas must be less than 25% of the occupational exposure limit for the gas.
 Where a toxic or asphyxiant gas is pumped, the booster pump must be located in a well-ventilated area.

Installation

S900-01-880 Issue C
 You must be able to purge the pumping system with an inert gas when you shut down the pumping system, to dilute dangerous gases to safe concentrations. Contact Edwards or your supplier if you are in doubt.
If the booster pump is to be fitted in a new system, ensure that all preliminary pipelines have been installed and that a suitable base for the booster pump has been prepared before you start installation. Ensure that the following services and facilities are available for connection to the booster pump:
 Electrical Supply.  Backing pump.  Inlet screen (if required, to prevent debris from entering the pump during commissioning).
3.3 Unpack and inspect
WARNING
Use suitable lifting equipment to remove the booster pump from its packaging. If you do not, you can cause injury to people, or you can damage equipment. Refer to Section 2.2 for pump mass.
Remove all packing materials, remove the booster pump from its packing box, remove the protective covers from the inlet and exhaust ports, and inspect the pump. If the booster pump is damaged, notify the supplier and your carrier in writing within three days; state the Item Number of the pump together with the order number and supplier's invoice number. Retain all packing materials for inspection. Do not use the pump if it is damaged. If the booster pump is not to be used immediately, refit the protective covers. Store the pump in suitable conditions as described in Section 6 of this manual.
3.4 Move the booster pump to its operating location
Use a fork-lift truck to move the booster pump (attached to the shipping crate) to the installation location. Lift the booster pump with the forks well outward of the centre of mass, to prevent the booster pump tipping over when you move it. When the booster pump has been unpacked and disconnected from its shipping crate, lift the pump; refer to Figure 12 and use one of the following two methods: 1. To use lifting-bolts and chains (see details A and B):
 Fit two 3/4-10 lifting bolts (1, not supplied) to the pump.  On a booster pump with a motor: fit a suitable size lifting bolt to the motor (if necessary).  Attach lifting chains to the lifting bolts (1, 2) and connect the chains to your lifting equipment. 2. To use slings (see detail C):  Attach slings (4) around the pump body.  Connect the slings to your lifting equipment. You must use lifting equipment and chains/slings which are suitably rated for the mass of the pump. Use caution when you move a booster pump with a direct drive motor attached; fix the pump in position immediately after it has been located. Refer to Tables 4 to 8 for the mass of the pump, and to Table 11 and Figure 12 for the centre of mass location.

3.5

Locate the booster pump
WARNING
Use suitable lifting equipment to move the booster pump. If you do not, you can injure yourself or damage the pump. Refer to Section 2 and Table 11 for pump mass information.

You must mount the booster pump on a smooth, flat, level surface. The degree of variation in level should not exceed 5.2 mm m-1 (0.063 inch ft-1) in any direction. Check that all four pump feet contact the mounting base. Do not distort the booster pump body. You must securely fix the booster pump in position before you operate it.
Before you install the pump, check that there are no foreign materials or debris in the vacuum pipelines or in the impeller cavities in the body of the pump. Check that the impellers rotate freely.
The booster pumps are designed for optimal performance in clean environments with ambient temperatures as specified in Section 2.1. If you use the booster pumps in areas of higher temperatures, this will result in higher discharge temperatures, and possible over-temperature cut-outs. If you use the booster pumps in dirty locations or where oil vapour is present, this can result in overheating of the motor, belt slippage, or premature wear. When the pump is used in a dirty environment, ensure that you inspect and clean the equipment as necessary.
Locate the pump as close as possible to the equipment/chamber which will be evacuated. Position the pump so that electrical and vacuum pipeline connections can be easily made. Provide adequate access space around and above the pump, so that the pump can be easily serviced. Avoid long lengths of vacuum pipeline from the equipment/ chamber being evacuated to the booster pump.
The booster pumps are precision balanced devices. You must mount the booster pump on a sufficiently rigid base, and secure it to the floor to reduce potential system vibration. Vacuum pipelines attached to the booster pump can vibrate excessively if they are not properly supported or secured. Booster pump vibration is usually the results of insufficient support.
3.6 Connect the vacuum and exhaust pipelines
WARNING
Install all pipelines so that they do not present a trip hazard. If you do not, you can cause injury to people.

CAUTION
Install a removable inlet filter so that particles, debris or loose components cannot enter the pump during commissioning.
All vacuum pipelines should be as short as possible and should be no smaller than the diameter of the booster pump inlet. When you need to install a long length of pipeline, use pipe which has a diameter larger than the diameter of the pump inlet. Conductance-check the pipelines to ensure that the pumping speed of the system will not be decreased. Do not install restrictive pipelines or valves in the exhaust pipeline; these may cause the exhaust pressure to exceed atmospheric pressure. If necessary, consult Edwards for advice and assistance when you need to size long lengths of pipelines.
Use a clean rag dampened with Loctite Safety Solvent (or another cleaning solution compatible with the gases to be pumped) to clean the booster pump impellers and flanges if they have accumulated dirt during installation or storage. It is important that the flanges are clean; if they are not, you will not be able to obtain a good vacuum seal.
Install an isolation valve in the foreline to the booster pump, so that the pump can be isolated from the chamber/ vacuum system.

S900-01-880 Issue C
3.6.1 Vacuum inlet pipeline
CAUTION
Ensure that foreign matter (particulate) cannot get into the pump. If it does, it can cause serious damage and premature failure of internal pump part.
Ensure that the vacuum pipeline is leak-tight. Install a flexible connection between the booster pump inlet and the vacuum pipeline, to reduce vibration and prevent booster pump body distortions. Properly support the pipelines, to minimise vibration. You must not use the body of the booster pump to support long lengths of pipelines.
We recommend that you install a high-vacuum, fully-opening valve, for ease of start-up and so that you can check the pump ultimate pressure with no gas throughput. This valve will allow you to isolate the vacuum pumps from the vacuum system. We recommend that you install a vacuum pressure gauge, so that you can monitor pump performance. Install a vent valve in the booster pump inlet or foreline. Install a filter-silencer, to prevent the entry of foreign materials into the system.
Ensure that the vacuum system and connecting pipelines are clean and free of weld splatter, dirt or grit.
Edwards recommends that you install inlet filters and traps, to prevent entry of foreign matter. If you use inlet filters and traps, we recommend that you change the pump oil more frequently.
You may need to install other devices such as interstage temperature switches, timers, vacuum pressure switches and so on, to protect the booster pump from thermal and mechanical overload. This will depend on the size of the booster pump, the backing pump capacity and vacuum chamber size.
3.6.2 Accessory port pipelines
Accessory connection ports are provided in the body of the booster pump. You may use these ports to connect vent valves and vacuum pressure gauges. Vacuum pressure gauges should be connected as follows: remove the 0.5 inch 'O' ring plug (0.75-16 straight thread) and fit a vacuum ball valve, connected to an elevated vacuum pressure gauge. Use a short run of vacuum pipe so that the valve is not too close to the hot body of the booster pump.
Coat all threaded vacuum joints with a liquid thread sealant (such as Loctite 714 or equivalent). Do not use tape thread sealant, which will create small vacuum leaks.
3.6.3 Exhaust pipeline
WARNING
The temperature of parts of the exhaust pipeline may exceed 70 °C (160 °F). Under extreme conditions, surfaces of the booster pump may reach 190 °C (375 °F). Provide adequate guarding and warnings, to protect people from the hot surfaces.
The diameter of the exhaust pipeline must be no smaller than the diameter of the booster pump outlet. Ensure that the exhaust gases (which may include pump oil and process gases) are safely handled and treated, in accordance with local, State and National regulations.
When you install a horizontal booster pump on an oil-sealed backing pump, mount the booster pump above the backing pump inlet, so that oil does not collect in the booster pump. Install sample ports in the exhaust pipeline, so that you can check system temperatures and pressures. Do not install restrictive piping or valves in the exhaust pipeline, as these may cause the exhaust pressure to exceed atmospheric pressure.

Belt drive booster pump installation
WARNING
Never operate the booster pump without proper safety guarding installed.

Ensure that the alignment of the pulleys and the tension of the booster pump drive belt are correct. Comply with the installation requirements specified in this manual and inspect the drive system regularly, to avoid mechanical problems and unnecessary repairs. Belt axial load should be less than 890 N (200 lb). Table 12 shows the minimum permissible pulley diameters. Contact Edwards for advice if you want to use a motor with a power rating which exceeds 30 kW (40 h.p.). Obey all of the safety precautions outlined in Section 3.1

Pulley misalignment can damage the bearing, belts and seal(s). Pulley alignment does not change during operation. The motor and booster pump drive shafts must be parallel to avoid uneven loading of belts. Your motor and drive components must comply with local and national safety regulations. Check for free rotation of the booster pump before you start the booster pump.
New belts usually lose some tension during initial operation, and you should re-check the belts during the first few days of operation. Tension all belts in accordance with the belt manufacturer's instructions. Excessive tension can induce unnecessary loading on the booster pump bearings and bending moments on the booster pump drive shaft. Extreme over-tensioning may cause the pump drive shaft to fail, due to fatigue damage.
Booster pumps with belt drive systems supplied by Edwards have the pulley and belt tension already preset. Recheck the alignment and tension (See Tables 13 and 14) before initial operation; use the following procedure:
1. Ensure that the shaft, hub and pulley components are free of lubricants, corrosion and protective coatings.
2. Check the pulley alignment with a straight edge or tight cord. The pulley faces must contact the straight edge at all four points. Misalignment will significantly increase belt wear.
3. If pulley alignment or removal is required: loosen the motor hub set screws several turns; remove one set screw completely; install the set screw in the centre position and then tighten the screw to free the locking bush. Reposition the pulley and then reinstall the set screws in the original position in the locking bush. Tighten the set screws evenly to the specified torque. Note that the locking bush number is stamped on the inner hub face.
4. Belt span distance, belt deflection and deflection force determine the correct belt tension. Determine the span distance between contact points on the pulleys. The deflection must be 0.397 mm per 25.4 mm of span (1/64 inch per 1 inch of span).
5. Determine the correct belt force, based on the smallest pulley diameter and belt type. Edwards supplied belt systems are usually a 3 groove "B" design. Check each belt for even loading. Uneven loading indicates pulley misalignment or non-parallel shafts.
6. Ideal tension is the minimum tension to overcome peak loading. Never exceed 1.25 times the force specified in Table 14. Lock down the tension adjustment mechanism.
7. Turn the pulleys over three times by hand. Check for free and easy rotation.
8. Recheck the tension before you refit the safety guards and operate the booster pump.
When any one belt needs to be replaced, replace all of the other belts at the same time. Check the tension frequently during the first few days of operation. Never apply belt dressing. If you are installing your own belt or pulley drive

Direct drive booster pump installation

WARNING
Never operate the booster pump without proper safety guarding installed.

Drive coupling alignment must be correct. Misalignment or a worn out coupling spacer (spider) will damage the booster pump bearing and seal(s). Comply with the installation requirements specified in this manual and inspect the drive system regularly, to avoid mechanical problems and unnecessary repairs.
If you install your own motor and drive components, they must comply with all local and national safety regulations. Follow all of the safety precautions outlined in Section 3.1.
Direct drive booster pumps are supplied with the motor coupling already set. Recheck the alignment before initial operation. Values listed below are for L190 couplings. Contact Edwards for advice on other coupling sizes. Check the condition of the coupling spider every 2000 hours.
1. Ensure that the shaft, coupling and other components are free of lubricants, protective coatings and burrs.
2. Slide one half-coupling onto each shaft. Check that the keys fit tightly.

S900-01-880 Issue C
3. Position the hubs on the shafts so that there is a gap of approximately 25.4 mm (1.0 inch) between the hub recesses for the polymer spider, and so that there is an equal amount of support for both coupling halves. When one of the half-couplings is in its final position, tighten the set screw (½-13) on the half-coupling to a torque of 61 to 68 N m (45 to 50 lbf ft).
4. Slide back the free half-coupling and install the polymer spider. Reposition the free half-coupling to the correct spacing, and tighten the set screw as described above.
5. If you cannot slide back the hub: torque the second half-coupling at the correct spacing; separate the components and install the polymer spider; reassemble the coupling hubs together with the correct spacing.
6. Check for parallel alignment with a straight edge across the two coupling halves at several places around the coupling. Do not rotate the coupling. Measure the space under the straight edge. The misalignment measurement must be less than 0.013 mm (0.005 inch). Correct alignment will ensure the best performance and longest coupling life. Reposition the shafts if the maximum misalignment is exceeded.
7. Determine the angular alignment across the coupling. Take the measurements fromthe surface where the couplings neck down from the spider diameter to the diameter with the set screw(s). Determine the maximum and minimum values. The difference between these two measurements must be less than 0.38 mm (0.015 inch). Reposition the shafts if the maximum tolerance is exceeded. Recheck for parallel alignment if you reposition the coupling.
8. Rotate the coupling after you have set the proper alignment. The shaft should rotate freely and easily. Never operate a coupling above the maximum permissible power of the r min-1 (r.p.m.) rotation speed indicated (stamped) on the coupling. Never operate the booster pump at speeds above 3600 r min-1 (r.p.m.).
9. Install proper safety guards before you operate the booster pump.

Fill the booster pump with oil
WARNING
Changing the oil in a booster pump from hydrocarbon to PFPE (Fomblin) could potentially cause a safety hazard. Fomblin pumps are generally used in hazardous applications which may involve the pumping of gases with high concentrations of oxygen. If hydrocarbon oil comes into contact with gases with an oxygen concentration greater than 25%, an explosion can occur. Therefore, if you want to convert a booster pump that has been used with hydrocarbon oil to use PFPE (Fomblin) oil, you cannot simply flush the pump with new PFPE oil. You must return the pump to a Edwards Service Centre for overhaul and cleaning by qualified Edwards service engineers. The change in oil type requires a complete strip-down of the pump, and thorough cleaning of all parts, so that all traces of hydrocarbon oil are removed.

CAUTION
Ensure that you use the proper grade of oil and that the oil levels in the pump are correct. If you do not, pump performance will be affected and the pump may be damaged.

Ensure that the oil-levels in the booster pump are correct before you operate the pump. Check the oil levels daily. Always use the correct oil. Do not use oils other than those specified in this manual; if you do, you will invalidate the warranty of the pump. Refer to Section 5.3 for maintenance frequencies. The use of substitute oils may make the booster pump unsafe. If you use the booster pump on harsh and dirty applications, you will need to change the oil more frequently.

3.9.1 Hydrocarbon oil

Before you operate the booster pump, ensure that the oil levels are correct (See Table 15). The oil levels should be at the centre position of each sight-glass. Do not add oil while the booster pump is operating. Shut down the booster pump and vent the pump to atmospheric pressure before you fill the pump with oil, or drain oil from the pump.
The booster pump has two oil reservoirs:
 Bearing housing, drive end.
 Bearing housing, gear end.
Refer to Figures 1 and 2 for the locations of the oil filler and drain ports.
With the booster pump shut down and at atmospheric pressure, add V-Lube H oil through both filler ports until each oil-level sight-glass is half full. Do not overfill with oil, or allow the oil level to fall below the bottom of the sightglass. If you have overfilled a reservoir, oil may spill over into the body of the pump and contaminate the vacuum system.
If you overfill the drive end reservoir, the booster pump may make a squealing noise (from the seal) during operation. Lower the oil level slightly to eliminate the noise.
The bearings in the drive end reservoir are splash lubricated from an oil slinger that dips into the oil sump. The gears are lubricated by partial immersion in the oil sump. Splashing from the gears lubricates the bearings.

S900-01-880 Issue C
When the booster pump is in operation, the oil level will fluctuate due to the pumping action of the gears and slinger. If you cannot see an oil level because the sight-glass is dirty, remove the sight-glass (when you change the oil) and clean the viewing surface.
Each time you remove a filler plug or drain plug, inspect the plug 'O' ring for cuts or damage, and replace it as necessary. The plug 'O' rings need to provide a vacuum seal for correct pump operation.
3.9.2 Perfluoropolyether (PFPE) oil
WARNING
Only use the type of PFPE oil specified below. If you use another type of oil, this can result in an explosion.
Before you operate the booster pump, ensure that the oil levels are correct (See Table 15). Add oxygen service (PFPE) oil into the reservoirs as necessary, as described in Section 3.9.1. Each oil-level should be at the centre position of the oil-level sight-glass. Oxygen service equipment requires the use of PFPE oil. You must only use Fomblin® Y-25/6 oil. Do not use another type of oil, or mix oil types when you add oil. We recommend that you return oxygen service booster pumps to a Edwards Service Centre if major repairs are needed. Minor repairs can be made in the field. Because of the possibility of a dangerous reaction to dirt and chemical compositions in an oxygen rich environment, absolute cleanliness of parts, tools, wipers and technician hands and clothes is required.

Installation

S900-01-880 Issue C
3.10 Electrical connections
3.10.1 Electrical supply configuration
WARNING
The electrical installation must conform to all local and national safety regulations. Use a suitably rated fused and protected electrical supply and an earth (ground) point.
WARNING
Install electrical cables so that they do not present a trip hazard that could result in injury to people.
WARNING
Provide suitable strain relief on the electrical supply cable. If you do not, the cable (or wires in the cable) may become disconnected from the pump, and there may be a risk of injury or death by electrical shock.
WARNING
You must be able to isolate and lock-out the electrical supply from the booster pump. If you do not, there will be a risk of injury or death by electrical shock during maintenance or servicing.
CAUTION
Configure the electrical supply to the booster pump so that the pump is automatically switched off if the backing pump stops. If you do not, the booster pump may overheat and be damaged.
Note: Connect the electrical supply to the motor through a contactor which has a manual reset control.
A suitably trained technician must correctly install the necessary overloads, motor starter, and control and safety devices, and connect the electrical supply to the booster pump. Control devices may include temperature switches and pressure switches. If the necessary control and safety devices are not installed, this may invalidate any Edwards warranty, and can result in serious injury or death, and damage to the equipment.
Incorporate a manual restart, to prevent automatic cycling in the event of an overload. The booster pump control system must be configured so that a hazardous condition does not arise after electrical supply failure, or when the electrical supply is restored after a failure. Controls should be clearly visible and easily accessible, and be organised to help the operator to understand their functions and their effect on the booster pump and vacuum system.
All electrical connections and controls must meet local and national regulations and standards. You must incorporate over-current protection and a mains electrical disconnect. Ensure that all electrical wiring is protected from dripping water and has appropriate strain relief. Where necessary, incorporate additional controls to protect the equipment and people if the performance limits of the booster pump may be exceeded.
Where necessary, depending on booster pump size, backing pump capacity and chamber size, incorporate other devices such as interstage temperature switches, timers or vacuum pressure switches, to protect the booster pump from thermal and mechanical overload.
Because of the wide range of applications for the booster pumps and the various vacuum systems and configurations, specific sizes or models of the protective equipment, safety devices and control devices cannot be specified in this manual. Information used in the selection of these devices can be found in Section 2. Contact Edwards for recommendations on the protection and safety devices necessary for your specific application.

3.10.2 Check the direction of rotation
WARNING
Blank off the inlet or connect the booster pump to the vacuum system before you check the direction of rotation. If you do not, there is a danger of entanglement or of objects being trapped in the rotating rotors.
It is possible for the three phase electrical supply to the motor to be phased incorrectly. If the supply is phased incorrectly, the rotors will rotate in the reverse direction or remain stationary. Watch the motor fan and switch on the electrical supply to the booster pump for two or three seconds, then switch the pump off. The correct direction of rotation is shown by an arrow on the motor: see Figures 1 and 2. If the direction of rotation is incorrect, isolate the external electrical supply, correct the electrical connections to the booster pump, then perform the direction check again.

5 Maintenance

5.1

Safety information
WARNING
Obey the safety instructions given below and take note of appropriate precautions. If you do not, you can cause injury to people and damage to equipment.

 A suitably trained and supervised technician must maintain the booster pump.
 Dismantle the booster pump in a clean workshop environment, with the correct tools and safety facilities available.
 Ensure that the maintenance technician is familiar with the safety procedures which relate to the pump oil and the products pumped. Wear appropriate safety-clothing when you come in contact with contaminated components. Dismantle and clean contaminated components inside a fume- cupboard.
 Check that all the required parts are available and of the correct type before starting work.
 Isolate the pump and other components from the electrical supply so that they cannot be operated accidentally.
 Allow the pump to cool (so that it is at a safe temperature for skin contact) before you start maintenance work.
 Vent and purge the pumping system with nitrogen before you start maintenance work.
 Do not reuse 'O' rings and Co-Seals.
 Dispose of components and waste oil safely (See Section 6.2).
 Take care to protect sealing faces from damage.
 After maintenance is complete, recheck the direction of pump rotation if the electrical supply has been disconnected.
 The booster pump and pump oil will be contaminated with the process chemicals that have been pumped during operation. Ensure that the pump is decontaminated before maintenance and that adequate precautions have been taken to protect people from the effects of dangerous substances if contamination has occurred.
 Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the pump has been heated to 260 oC (500 oF) and above. These breakdown products are very dangerous. Fluorinated materials in the booster pump include oils, greases and seals. The booster pump may have overheated if it was misused, if it malfunctioned, or if it was in a fire. Edwards Material Safety Data Sheets for fluorinated materials used in the booster pump are available on request: contact your supplier or Edwards.
 If necessary, maintain the motor as specified in the manufacturers information supplied with the motor.
 Leak test the system after maintenance and seal any leaks found, to prevent leakage of dangerous substances out of the system and leakage of air into the system.
5.2 Leak detection
Carry out a leak test if the specified booster pump ultimate vacuum cannot be achieved. A properly carried out leak test will isolate sections of the pipelines until the leak-source is found. The use of a leak detector will speed the process. If required, contact Edwards for more information.

Maintenance

S900-01-880 Issue C

5.3 Maintenance plan

Table 16 details the maintenance operations necessary to maintain the booster pumps in normal use. We recommend that you change the oil more frequently if the booster pump is used under severe operating conditions, such as contamination within the vacuum system or excessively high operating temperatures within the booster pump. (The operating conditions will determine the frequency of oil changes.) Worn pulleys and over tensioning shortens belt life by as much as 50%. If wear allows the belts to contact the bottom of the pulley, slippage and belt burn may result. Convex wear on the side of the belts indicates pulley groove wear. Alignment problems are identified by significant wear on one side of a belt only.

5.4 General maintenance

Refer to Sections 3.1 and 4 before you shut down the booster pump for maintenance, and restart the booster pump after maintenance. Only allow suitably trained and supervised technicians to maintain the booster pump.
5.5 Oil-level checks

WARNING
Never attempt to add or drain oil while the booster pump is operating. Shut down and lock-out the booster pump and vent it to atmospheric pressure before you fill the pump with oil, or drain oil from the pump.

CAUTION
Ensure that you use the proper grade of oil and that the oil levels in the pump are correct. If you do not, pump performance will be affected and the pump may be damaged.
Look at the sight-glasses (see Figures 1 and 2). The oil level in each reservoir should be in the centre position on the sight-glass. If you need to add oil:
1. Shut down the vacuum system and vent it to atmospheric pressure.
2. Remove the oil filler plug (see Figures 1 and 2).

Maintenance

S900-01-880 Issue C
3. Add oil as necessary until the oil level is half-way up the sight-glass. Only use oil specified in this manual. 4. Inspect the plug 'O' ring for cuts or damage, and replace it as necessary. Refit the oil filler plug.
5.6 Changing the oil
WARNING
Changing the oil in a booster pump from hydrocarbon to PFPE (Fomblin) could potentially cause a safety hazard. Fomblin pumps are generally used in hazardous applications which may involve the pumping of gases with high concentrations of oxygen. If hydrocarbon oil comes into contact with gases with an oxygen concentration greater than 25%, an explosion can occur.
Therefore, if you want to convert a booster pump that has been used with hydrocarbon oil to use PFPE (Fomblin) oil, you cannot simply flush the pump with new PFPE oil. You must return the pump to a Edwards Service Centre for overhaul and cleaning by qualified Edwards service engineers. The change in oil type requires a complete strip-down of the pump, and thorough cleaning of all parts, so that all traces of hydrocarbon oil are removed.
WARNING
Never attempt to add or drain oil while the booster pump is operating. Shut down and lock-out the booster pump and vent it to atmospheric pressure before you fill the pump with oil, or drain oil from the pump.
WARNING
Allow sufficient time for the booster pump to cool before you change the oil. If you do not, you can be injured by the hot oil.
Use the following procedure to drain and refill each reservoir with oil: 1. Shut down the vacuum system and vent it to atmospheric pressure. 2. Place a suitable container under the drain plug (see Figures 1 and 2), then remove the drain plug and allow the
oil to drain out of the pump. 3. Inspect the plug 'O' ring for cuts or damage, and replace it as necessary. Refit the drain plug, then dispose of the
oil: refer to Section 6. 4. Fill the oil reservoir with oil: refer to Section 5.5.
5.7 Coupling maintenance
1. Shut down the vacuum system and vent it to atmospheric pressure. Allow the booster pump to cool to a safe temperature.
2. Remove the safety guards when the pump is in a safe state. 3. Inspect the coupling as described in 3.8. Replace any worn or damaged parts. 4. Refit the safety guards.
5.8 Belt drive maintenance
1. Shut down the vacuum system and vent it to atmospheric pressure. Allow the booster pump to cool to a safe temperature.

2. Remove the safety guards when the pump is in a safe state. 3. Inspect the belts as described in Section 3.7. Replace any worn or damaged belts. 4. Refit the safety guards.
5.9 Check the bearing condition
1. Shut down the vacuum system and vent it to atmospheric pressure. Allow the booster pump to cool to a safe temperature.
2. Remove the safety guards when the pump is in a safe state. 3. Loosen the coupling and or belts to remove tension from the drive shaft. 4. Use a dial indicator on the shaft to determine the end play. Total end play must be less than 0.12 mm (0.005
inch):  If the end play is not excessive, continue at Step 5.  If the end play is excessive, contact your supplier or Edwards to arrange for a rebuild of the pump. 5. Refit the safety guards.
5.10 Clean the motor and drive
1. Shut down the vacuum system and vent it to atmospheric pressure. Allow the booster pump to cool to a safe temperature.
2. Remove the safety guards when the pump is in a safe state. 3. Use a compressed air line or a soft brush to remove any dirt and dust from the motor and drive components. 4. Refit the safety guards.
5.11 Check the timing
WARNING
Use the appropriate personal protective equipment when you adjust the impeller timing.

Only suitably trained personnel should inspect the impeller timing. Edwards service engineers are available to carry out such inspections on site or at a Edwards Service Centre. Failure to properly time the booster pump can cause catastrophic damage to the pump.
5.12 Troubleshooting
Troubleshooting and recommended solutions are provided in Table 17.

Maintenance

S900-01-880 Issue C

No pump will give good results on a poor vacuum system. If the vacuum performance in the system is unsatisfactory, the usual cause is leakage into the system. If your system has poor vacuum performance, you should first tighten all connections and fittings, and check that all valves are closed. Use liquid sealant to make the pipeline connections; do not use Teflon tape.
A pressure rise test will help to localise a vacuum leak. To carry out such a test, successively isolate and evacuate each section of the vacuum system, then measure the in-leakage rate (the pressure rise) of each isolated section, to isolate the leak. Use a vacuum leak detector to speed up this process.
If required, Edwards offers vacuum leak detection services.
