A65201֖880 IssueS Page 4 Edwards Limited 2007. All rights reserved.Edwards and the Edwards logo are trade marks of Edwards Limited. > Introduction The Edwards RV rotary vane pump is shown in Figure1. Refer to Figure1 for item numbers in brackets in the following descriptions. The RV pumps are two-stage, oil-sealed, sliding-vane vacuum pumps. The pump has NW25 inlet (4) and outlet (7) ports, a gas-ballast control (5) and a mode selector (11). When the pump is switched off, an inlet-valve seals the inlet and prevents the suck-back of air and oil into the vacuum system.The RV3 and RV5 pumps...

To pump high vapour loads, gas-ballast is delivered into the pump to prevent condensation of the vapour carried by the pumped gases.Air can be introduced to the low vacuum stage through the gas-ballast valve. Alternatively, an inert gas such as nitrogen can be supplied through a suitable external valve.The gas-ballast control has three positions: Closed (position0ђ) Low flow (positionIђ) High flow (positionIIђ). > The pump-shafts and rotors are made of high-grade cast-iron. The pump-body and oil-box are made from cast-aluminium. All surfaces of the pump which are exposed to the pumped gases...

A65201֖880 IssueS > Technical data Note: The performance characteristics described below are for use with hydrocarbon oil. The positions of the mode selector and the gas-ballast control define the performance characteristics of the pump. These performance characteristics are listed fully in Tables3 and4.Table5 gives the ultimate vacuum and maximum water vapour inlet pressure for each of the six possible combinations of control positions. The curves0, I, andII in Figure2 show the relationship between inlet pressure and pumping speed for High Vacuum mode Figure 2 - Performance characteristics...

We recommend that you do not use a hydrocarbon-prepared RV pump for pumping hazardous substances. PFPE-prepared pumps are suitable for oxygen applications: refer to Section8. You must ensure that the RV pump is suitable for your application. If you have any doubt as to the suitability of the RV pump for your application, refer to the Edwards guidelines on vacuum pump and vacuum system safety (see the Associated publications at the end of the Contents list at the front of this manual).A suitably trained and supervised technician must install your RV pump. Obey the safety instructions listed...

If you have a bareshaft pump, fit the motor to the pump now: refer to Section9. > Ensure that the motor is correctly configured for your electrical supply. If you operate the pump when the motor is not correctly configured for the electrical supply, you will damage the motor. Refer to Figure4 for the item numbers in brackets.Ensure that the voltage shown on the voltage indicator (4) in the motor-cover corresponds with your electrical supply voltage. If it does not, you must change the configuration of the pump-motor to match your electrical supply voltage; use the procedure below.1.Undo the...
