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.
