622 5VR CE 18.5kW

Process Isolation Boosters are designed to be used in conjunction with rotary-piston, liquid ring, rotary vane and dry vacuum pumps to increase pumping speed at working pressures and shorten pump down time significantly. The Process Isolation Boosters can be mounted separately or on the inlet of the backing pump to create a compact integrated package.

Features and Benefits
