Edwards Stokes Booster

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

The 6” Series are 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. Also By-pass variants are available which eliminate the need for pressure switches making the 6” Series one of the most versatile and flexible boosters.

Product Features

PERFORMANCE

Faster pump down time due to unique hydrokinetic drive. Larger displacement than equivalent competitor models.

SIMPLICITY

Continuous operation at all pressures. Simple installation with no need for pressure switches, bypass lines or variable frequency drives.

RELIABILITY

Automatic overload protection and reliable shaft seal design.

ROBUST OPERATION

Up to date technology – continued investment in design and technology improvements. 

NO OIL SEAL RESERVOIR

No need to monitor and top up an external oil reservoir to protect the pump and ensure Atex compliance.

ATEX & FOMBLIN

Wide range of options available for every application.
