Welch Rotary Vane Vacuum CRV Pro 30 Series

The new CRVpro family of direct drive vacuum pumps offer enhanced reliability and longer service intervals compared to other vacuum pumps.

The CRVpro family consumes 36% less oil than comparable pumps.

Three features encourage these benefits:

1)  10 ° C lower operating temperature from  comparable pump.

2)  Slower corrosion.

3)  40% more oil capacity than comparable pump.

Chemically resistant coating in oil bath and pump module which protect immovable components. CRVpro family includes all the features you would expect in a direct drive rotary vane pump: gas ballast, coercive oil lubrication, anti-suckback mechanism and thermal overload protection. 

Suitable applications include freeze drying, degassing, vacuum ovens and concentrators.

Direct drive rotary vane pumps are not recommended for filteration, aspiration, drying electrophoresis gels, or other applications requiring vacuum level above 30 torr.
