Two Stage Rotary Vane Pumps, Edwards E2M18, NEW

One Stage, Two Stage Rotary Vane Pumps, Edwards, E1M18/E2M18, NEW
E2M18 115/200-230V, 1-ph, 50/60Hz with IEC60320 connector A36317984
The EM range of oil-sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications.
The E1M18 and E2M18 pumps are direct drive, sliding vane pumps. The pump is oil sealed and designed for reliable, long-term operation. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single-phase or three-phase (four-pole) motor.
