The Edwards Rotary Vane EM (small) Series pumps are rugged, mechanical oil-sealed pumps with speeds ranging from 0.7 to 28 m3/hr depending on model size and stage. Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit your specific application needs.
These pumps have a well-proven, positive pressure oil lubrication system developed by Edwards to ensure correct lubrication in all operating modes, particularly under high gas loads where oil starvation is a common problem with other pumps.
Integral oil pump ensures an adequate oil flow through the stator/rotor assembly at all times
Only clean degassed oil is supplied to the high vacuum stage on two-stage pumps
System is much less dependent on correct oil levels in the reservoir than other pump designs
Pumps can operate with oil levels as low as 50–70% of the maximum fill level
