The CRVpro series two-stage, direct drive rotary vane vacuum pumps are fitted with Class 1, Groups C and D, and Class 2, Groups F and G explosion proof motors. Be sure to use a certified electrician for proper installation of these pumps. Conduit wiring installation required. No cord, plug, or switch provided.

A unique air flow design allows the pumps to run 10°C cooler than standard rotary vane pumps, leading to reduced chemical activity within the pump and less oil consumption—up to 36% less than comparable pumps. The oil-sealed pumps feature a gas ballast, forced oil lubrication, anti-suck back valve, low noise level, and thermal overload protection. The gas ballast uses either outside air or dry inert gas to reduce condensable vapors from entering the pump oil.

Ideal for use in freeze drying, degassing, vacuum ovens, and concentrators.
