Stokes 6″ series mechanical boosters are designed to be used in conjunction with rotarypiston, dry vacuum, rotary vane and liquid ring pumps to increase pumping speed at working pressures and shorten pump down time significantly. The Stokes 6″ series can be mounted separately or on the inlet of the backing pump to create a compact integrated package.strokes

Featuring an extra large diameter shaft, the Stokes 6” series has the capability for use with higher powered motors in addition to ensuring a uniquely rugged and durable mechanical booster. This allows the pumps to operate at their full displacement from atmospheric pressure with an appropriately sized backing pump.
