Description

Consumes up to 36% less oil than comparable pumps Runs 10°C cooler than comparable pumps. Slows corrosion. Has a 40% larger oil capacity than comparable pumps. Dilutes aggressive chemicals. Has a chemical resistant coating in the oil case and pump module. Protects non-moving parts. The CRVpro family includes all the features you'd expect in a direct drive rotary vane pump: gas ballast, forced oil lubrication, anti-suckback mechanism and thermal overload protection. CRVpro4 vacuum pumps can be used for applications such as freeze drying, vacuum ovens, schlenk lines, backing turbo molecular pumps, degassing, vessel/chamber evacuation. Direct drive pumps are not recommended for filtration, aspiration, drying electrophoresis gels, or other applications requiring sustained operation above 30 torr.
