Stokes Microvac
The most efficient rotary piston pump in the industry
Suitable for a broad range of industrial processes
If you have a harsh general industrial application, the Stokes Microvac remains a perennial favourite. It services a wide range of applications including heat treatment, metallurgy, automotive, PET processing, pharmaceuticals and general applications.
A proven, robust machine
For over 100 years, the Stokes Microvac has been delivering robust, reliable operations with maximum uptime. A large part of this is due to the efficient design that includes minimal moving parts.
Ready-to-install pump saves space
