Additional Views

The Welch CRVpro family of direct drive rotary vane pumps is the industry leader within the direct drive vacuum pump category. Service intervals are extended from three core features:

  1. Cool running. By running cooler relative to competitive direct drive pumps, agressive and corrosive chemical activity is reduced.
  2. Large Oil Capacity. By having a larger oil reservoir relative to competitive direct drive pumps, agressive and corrosive chemicals are diluted. This reduces their chemical activity.
  3. Internal surface protetion. Oil sump is PTFE coated, pump module has a black oxide coated.

The Welch CRVpro family of direct drive pumps includes all the features you'd expect:

  • Low noise level
  • Forced OIl Lubrication
  • Anti-suck back valve
  • Gas Ballast
  • cUL and CE Certification
  • CRVpro4, CRVpro6, and CRVpro8 have dual voltage (switch selectable) motors
