• Stokes 6" Mechanical Booster Pumps

    Stokes 6” series mechanical boosters are designed to be used in conjunction with rotary piston, dry vacuum, rotary vane, liquid ring, or on the inlet of the backing pump to create a compact integrated package. When coupled with one of the aforementioned pumps, the Stokes 6" mechanical boosters increase pumping speed at working pressures and significantly reduce pump down time.

    Available in bare-shaft or direct drive motor variants, horizontal or vertical gas flow and with a single mechanical seal or a Process Isolation variant with 5 mechanical seals for optimum protection from dust and particulate contamination in arduous applications. By-pass variants are also available, which eliminate the need for pressure switches making the 6” Series one of the most versatile and flexible boosters.
