Rotary Vane Pumps

Kurt J. Lesker (Jefferson Hills, PA) offers KJLC RV Series rotary vane pumps that feature an anti-suckback mechanism to prevent oil from back-flowing in the event of accidental shutdown, power failure, etc. A pressurized oil circuit assures constant lubrication regardless of the inlet pressure. A gas ballast valve helps reduce the amount of condensate that forms in the pump. Applications include research and development; backing for boosters, diffusion, and turbo pumps; freeze-drying; vacuum coating; gas handling; vacuum drying and degassing; HVAC servicing and manufacturing; and leak detection.
