CRVpro vacuum pumps

Two-stage direct-driven vacuum pumps

Two-stage direct-driven vacuum pumps

The new CRVpro family of direct drive vacuum pumps offers increased reliability and longer service interval vs. other direct drive rotary vane vacuum pumps. The CRVpro family consumes up to 36% less oil than comparable pumps.

They are nine models of CRVpro available. Ultimate pressure to 2x10-3 torr.

The benefits of CRVpro pumps are:

  • ● Reduced risk of chemical attacks and oil breakdown by diluting chemical vapors with a larger oil chamber

  • ● Slowing down corrosion by cool running operation

  • ● Provides a measure of protection from sublimed chemical vapors with coating on pump module and oil case.

  • ● 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.

  • These benefits lead to extended service interval.

    Depending on model, motor options include 1 Ph TEFC, 3 Ph TEFC, and 1 Ph ex proof motors.
