Page 12: Electrical Connection
To do so, briefly switch on the power and check whether a suitable cover (e.g. a blank flange) is sucked on at the intake port. If not, interchange two phases of the connection. Observe the direction arrow on the motor adapter. VWR Rotary Vane Pump ver 1.3 23.11.2020... -
Page 13: Change The Voltage Setting
Vacuum pump is shipped without oil inside to prevent possible spillage during shipment. Oil must be added prior to use! The vacuum pump is delivered with VWR RV+ Oil and can therefore be used for pumping out neutral gases and vapours. The oil fulfills the following functions in the vacuum pump:... -
Page 14: Storage
Even if a pump is stored for a long period with oil initially in good condition, check the oil when the pump is restarted, and change the oil if necessary. VWR Rotary Vane Pump ver 1.3 23.11.2020... -
Page 15: Intended Use
It is forbidden to use the pump for applications deviating from the technical data stated on the type plate or the conditions stated in the supply contract, or to operate it with missing or defective protective devices. The rotary vane pumps VWR RV2.5+, VWR RV3+, VWR RV6+, VWR RV8+, VWR RV18+ are not suited for pumping liquids. -

8.0 Product Specifications 8.10 Overview and Description The rotary vane pumps VWR RV2.5+, VWR RV3+, VWR RV6+, VWR RV8+, VWR RV18+, are oil-sealed, two-stage rotary vane vacuum pumps. The drive motor is directly flange-mounted onto the motor cover of the pump holder. The pump shaft and the motor shaft are connected to each other by an elastic coupling. -
Page 20: Area Of Application
WARNING! The rotary vane pumps must not be used for extracting explosive gases or vapours. The rotary vane pumps must not be operated in rooms which might contain explosive gases. VWR Rotary Vane Pump ver 1.3 23.11.2020... -
Page 21: Function
When the gas ballast valve opens (to the left) air flows into the compression space. The air flowing in keeps the partial pressure of the condensable medium so low that the pressure needed to open the outlet valve is reached before the medium condenses. VWR Rotary Vane Pump ver 1.3 23.11.2020... - Page 22 Should condensate form despite actuation of the gas ballast device, the suction port must be closed and the pump operated with gas ballast for a lengthy period (about 2 hours). VWR Rotary Vane Pump ver 1.3 23.11.2020...

Page 23: Operation
9.30 Operating temperature The function of the vacuum pump filled with VWR RV+ Oil is guaranteed between ambient temperatures of 10 °C and 40 °C. The lowest starting temperature is 12 °C. The pump must be vented on the suction-side (suction port open). -
Page 24: Use Of The Gas Ballast When Switching On
If the vacuum pump does not regain its former characteristics, this means that the oil is totally contaminated. In this case, the only remedy is complete cleaning followed by rinsing and filling with new oil, 7.40 Oil Change. VWR Rotary Vane Pump ver 1.3 23.11.2020... -
Page 25: Gas Ballast Control
Close connecting ports with a rubber stopper or other suitable cover to protect the pump against contamination. An intake screen is furnished to prevent loose particles from entering. WARNING!

Page 27: Repair And Maintenance
All other maintenance and service work may only be performed by the manufacturer or a dealer authorized by him. Beware of the pump parts being possibly contaminated by hazardous substances. Wear protective clothing if there is contamination. VWR Rotary Vane Pump ver 1.3 23.11.2020... -
Page 28: Oil Level Control
The oil must be topped up if the oil level falls to the lower mark. We recommend to operate pump with oil filling at upper marking FULL. This minimize the service needs and allows better dilution of contaminants. When additional oil is required, use only VWR RV+ Oil, pump performance is not guaranteed with other brands of oil. -
Page 29: Draining The Oil
If you have established that the old oil, which you have previously drained, was contaminated by condensate (e.g. water) then the gas ballast valve must be open. Drain the flushing oil. If the oil still appears heavily contaminated, the flushing procedure must be repeated. VWR Rotary Vane Pump ver 1.3 23.11.2020... -
Page 30: Frequency Of Oil Changes

Pump 12.50 Oil – Technical Data VWR RV+ Oil is a triple-distilled hydrocarbon oil using severely hydrotreated base stock. The oil is designed to resist breakdown at higher RPMs and operating temperatures of direct-drive vacuum pumps. The hydrotreating virtually eliminates aromatics and sulfur to give good resistance to sludge and varnish formation over time in corrosive environments. -
