The Duosealï¿½ high vacuum belt drive pump offers stable, high efficiency pumping below 1 Torr. Its lower pump RPM reduces internal wear compared to high-speed direct drives, and its cool running lowers maintenance requirements. This pump has less moving parts to increase pump durability, with a high contamination tolerance. It is excellent for degassing oils, plastics, epoxies, etc. Other uses include refrigeration service, dehydration, backing pump for diffusion pumps, and vacuum ovens and furnaces. This pump should not be operated continuously at pressures above 10 Torr. CFM 0.9, 25 L/min,Pump RPM 580, 1/3 Horsepower.
