The Welch CRV pro2 series direct drive rotary vane pumps offer superior reliability, long service life and can handle a variety of low vacuum needs. The Welch CRV pro series pumps are factory prepared with oil cases coated with PTFE (Polytetrafluoroethylene) commonly know as Teflon®. The outer surface of the pumping module also has a black oxide surface. Both coatings act to slow down metal corrosion. The CRV series have the unique feature of a much larger oil capacity than pumps of similar size. These pumps also run 10°C cooler than similar pumps from having a chemically resistant coating in the oil case and on the pump module, further protecting them from corrosion.
