Two-Stage Rotary Vane Pumps
  • 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.
  • Max Pumping Speed 6 m3/h (100 l/min)
  • Ultimate Pressure 2x10-3 mbar

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.

CRVpro6 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.
