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.
With a wide range of variants.
Over 80 years of time tested proven performance with
experienced service and technical support.
reliability and simple to use – large diameter shafts, ring feeder keyless gear locking system and dynamically balanced impellers.
Easy to maintain - single mechanical seal. Increased productivity – 5 seal design for optimal process protection.
Bareshaft or direct drive. Vertical or horizontal gas flow with by-pass versions available.

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.
