CRVpro Direct Drive Rotary Vane Vacuum Pumps

Additional Views

Three features to extend service intervals:

  • Cool running slows rate of corrosion and slows down rates of oil consumption
  • Large oil capacity minimizes the rates of oil breakdown and reduces chemical attack within pump
  • Internal surface protection on pump internals and PTFE coating on oil case slows chemical attack within pump.

Gas ballast uses either outside air or dry inert gas to reduce condensable vapors from getting entrained in pump oil.

Up to 10 dB quieter than competitive pumps

Anti-suckback valve prevents oil from being sucked into application in the event of power failure

CRVpro 2, 4, 6, 8 are switch selectable from 115V to 230V operation. Each pump includes power cord suitable for country use.

IP54 enclosure rating.

cUL and CE certification

Important note on Pumps with explosion proof motors: Always use a certified electrician for proper installation of pumps with explosion proof motors. Conduit wiring required. No cord, Plug, or switch included. Explosion proof rating is Class 1, Groups C and D, Class 2, Groups F and G.
