The reliable and versatile dry screw vacuum pump alternative for heat treatment and metallurgy industry processes.

The Stokes 212DRY-412DRY dry screw vacuum pumps offer the familiar reliable operation and performance, just as Stokes 212J and 412J pumps you have grown to rely on. With the Stokes DRY series you can improve your process operations, increase uptime and reduce maintenance at a minimal cost.

A robust rotary vane vacuum pump designed to deliver reliable performance with minimal hassle thanks to an integrated exhaust filter that operates at an optimal temperature to eliminate corrosion risks and prevent performance loss caused by external factors.

Built for continuous, long-lasting performance, the Microvane Series offers up to one year of maintenance-free operation, reduced oil consumption, and ultra-quiet performance as low as 52 dB(A). With advanced sealing and lubrication technology, internal wear is minimized, leading to fewer service interruptions and lower total cost of ownership. Less interruptions means a more dependable vacuum with minimal environmental impact and maximum uptime.

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. When coupled with one our pumps, the Stokes 6″ mechanical boosters increase pumping speed at working pressures and significantly reduce pump down time.

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