Rotary Piston Pumps
Vacuum rotary piston pumps are positive displacement pumps that use two or more intermeshing rotors to compress gases and vapors. They are commonly used in a wide range of industrial applications, including vacuum distillation, vacuum drying, and vacuum packaging. These pumps offer high pumping speed and high ultimate vacuum, and they are suitable for both rough and high vacuum applications. They also have a simple design and require minimal maintenance, making them a reliable and cost-effective solution for vacuum pumping.
Stokes Microvac RPP
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.
The Stokes Microvac rotary piston pumps set the standard for performance and reliability as the industries most efficient, space saving design. The design has been improved, upgraded and fine tuned to deliver even better dependability and productivity combined with minimal maintanance and process downtime.
