Our DUOSEAL® Welch vacuum pump has many applications such as degassing oils, plastics, epoxies, refrigeration service, dehydration, backing pump for diffusion pumps, vacuum ovens and furnaces. The DUOSEAL® Welch vacuum pump is stable with high efficiency pumping below 1 Torr. Using lower pump RPM reduces internal wear compared to high speed direct-drives, as well as cool running cuts down on maintenance requirements. With many models to choose from and fewer moving parts than our competitors’ products this Welch vacuum pump has an increase in durability.
