Oil Rotary Vane Pumps Two-Stage
Rotary vane pumps are considered wet, positive displacement pumps, with the term “wet” denoting that the gases being pumped are exposed to oil. The significant characteristic of oil sealed rotary vane (OSRV) pumps is the use of oil as a sealant and coolant.
Two-stage rotary vane vacuum pumps use a two stage compression offering high pumping speeds combined with low ultimate pressure. They are widely used in industrial, chemical, pharmaceutical, and food industries.
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.
Features and Benefits
- HIGH QUALITY OILS - with additives to prolong life whilst not impacting vapour pressure.
- LARGE WATER VAPOUR HANDLING CAPACITY - gas ballast valve.
- NO CUSTOMER WIRING - integral IEC connector.
- VISUAL INSPECTION OF OIL LEVEL AND CONDITION - O ring sealed sight glass.
- LOW SURFACE TEMPERATURE - forced air cooling.
- WIDE VOLTAGE MOTORS - all major countries covered with less variants.
