Description

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. 

CRVpro30 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.
