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 to increase pumping speed at working pressures and reduce the pump down time significantly.

1.590 - 6.630 m³/h

With a wide range of variants.

Robust

Over 80 years of time tested proven performance with experienced service and technical support.

Increased lifetime

reliability and simple to use – large diameter shafts, ring feeder keyless gear locking system and dynamically balanced impellers.

Reliable

Easy to maintain - single mechanical seal. Increased productivity – 5 seal design for optimal process protection.

Versatile

Bareshaft or direct drive. Vertical or horizontal gas flow with by-pass versions available.

Industry staple for over 100 years

For over 100 years, the Stokes mechanical booster pumps have offered time-tested, proven performance with experienced service and technical support you can rely on.

Configured for your needs

You can choose between bare shaft and direct drive with a range from 1800-3600 rpm. Depending on your industrial process you can opt for the vertical or horizontal gas flow orientation. The bypass variants eliminates the need of pressure switches making it one of the most versatile and flexible range of boosters.

Optimised design

These boosters are simple, reliable with increased lifetime. The ring feeder timeless locking elements allows for superior timing retention. The Process Isolation version comes with five mechanical seal design on the Stokes 6” provides optimal process protection from any dust and particulate contamination in your process.

Easy to maintain

The mechanical shaft seal leads to improved life and ease of serviceability. The larger sight glass and magnetic drain plugs facilities easy viewing of oil and prolongs life.
