Rotary Vane Pumps are positive displacement pumps which create vacuum through rotation of one or more vanes inside a cavity. They are sometimes also referred to simply as rotary vacuum pump or vane vacuum pump.Get more news about Two Stage Rotary Vane Vacuum Pump Seller,you can vist our website!

Welch Vacuum’s laboratory two-stage rotary vane pumps are always an option when an ultimate pressure level from 0.5 mbar to 1x10-4 mbar is required. Depending on the pump model the pumping speed range lies between 1.8 m³/h and 60 m³/h. Our new CRVpro family of direct drive lab vacuum pumps offers increased reliability and longer service interval vs. other direct drive rotary vane vacuum pumps. The CRVpro rotary vane pumps family consumes up to 36% less oil than comparable laboratory rotary vane pumps. Three features drive these benefits:

Runs 10°C cooler than comparable laboratory two-stage rotary vane pumps. Slows corrosion.
Has a 40% larger oil capacity than comparable rotary vane vacuum pumps. Dilutes aggressive chemicals.
Has a chemical resistant coating in the oil case and rotary vane pump module. Protects non-moving parts.
The CRVpro two stage rotary vane pump family includes all the features you'd expect in a direct drive two-stage rotary vane pump: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection.

It is designed for applications such as vacuum ovens, industrial applications, vacuum manifolds (Schlenk Lines), freeze dryers (Lyophilisation), glove boxes, vacuum concentrators, HVAC or as a backing pump for high vacuum systems such as mass spec devices.
