Rotary Piston Vacuum Pumps are legendary for their ruggedness and reliability, thanks to their slow rotational speed and robust, but simple design. Invented in the early 20th century, these type of pumps are still in use today and are popular in metallurgy, space simulation and vacuum drying applications. Trillium US Inc. manufactures the Univac line of Piston Pumps, which are based on the tried and true Stokes H-10/11 series pumps. As a bolt-for-bolt drop in replacement for the Stokes 412, 212 and 148, the Univac 400, 200 and 100 are a competitive alternative with much shorter lead times.
The Trillium Rotary piston vacuum pumps have managed to maintain their popularity in many industries, especially those requiring the evacuation of large manually loaded vacuum chambers. Due to their rugged design and large internal clearances, piston pumps have the unique ability to ingest debris and continue to operate. In addition, their simple design makes it possible for on-site maintenance from valve deck changes to full overhaul.
