The Stokes Microvac rotary piston pump has set the standard for performance, efficiency, reliability and repairability in the industry for over 80 years. The Stokes Microvac J series rotary piston pump has been improved, upgraded, and fine-tuned to deliver even better dependability and productivity combined with minimal maintenance and process downtime.
The integral oil distribution system eliminates external piping and delivers leak-free operation in a stylised design. A stiffer motor mounting platform cuts flexibility to minimise motor belt wear. A stylised oil reservoir cover and side cover ‘O’ rings improve sealing to eliminate oil leakage. An integral gas ballast valve built into the side cover allows quick adaptation to automatic gas ballast. A wide range of versatile accessories are available along with the ability to integrate with a range of mechanical boosters making the Stokes Microvac easily adaptable to suit your application and pumping requirements.
The Stokes Microvac ESI series (Extended Service Interval) sets the standard for reduced maintenance and extended service intervals in arduous applications. The ESI series incorporates all the time proven design features of the Stokes Microvac 412J while integrating key accessories and features for improved performance in the most demanding applications. The ESI series can be retrofitted with any Microvac and or mechanical booster combination to suit your special application and pumping requirements.
Over 80 years of time tested proven performance with experienced service and technical support. Dependability – low rotational speed enables longest
pump life cycle.
Easy on-site maintenance – robust simple mechanism for high reliability and ease of rebuild.
Configured for you – choice of pumping combinations available with a variety of boosters.
Up to date technology – continued investment in design and technology improvements.
