描述:
The CRVpro 4 is a two-stage, oil-sealed rotary vane vacuum pump designed for high reliability, low maintenance, and long equipment life. It features forced oil lubrication, anti-suckback valve, gas ballast with inert gas option, and dual voltage motor. The pump runs 10°C cooler than comparable pumps, reducing chemical activity and slowing oil consumption. The oil case has a PTFE coating and the pump module has a black oxide coating to slow metal corrosion. Applications include freeze drying, vacuum ovens, Schlenk lines, backing turbo molecular pumps, degassing, and vessel/chamber evacuation.
