Oil Rotary Vane Pumps Two-Stage
Because the gases being pumped are exposed to oil, rotary vane pumps are classified as wet positive displacement pumps. The use of oil as a coolant and sealer is a key feature of oil sealed rotary vane (OSRV) pumps.
Two-stage rotary vane vacuum pumps combine low ultimate pressure with high pumping rates with a two-stage compression mechanism. The food, chemical, pharmaceutical, and industrial sectors all make extensive use of them.
E2M Two Stage RVP
EM series pumps are rugged mechanical oil-sealed pumps with speeds ranging from 0.7 to 275 m3/hr (30 to 206 CFM). Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit specific application needs. EM products serve two major application sectors. In scientific and laboratory applications, the E2M0.7-2.5 and E2M18/28 are the ideal partners for your turbomolecular pump. In Industrial applications, E2M18/28, E2M40/80 and E2M175/275 offer very robust solutions in demanding applications.
