Edwards E2M28 Vacuum Pump, 380/400V 50HZ or 230/460V 60HZ, three phase A37333940
The Edwards 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.
Supplied with: Ultragrade 19 oil, NW25 O-ring and centering ring.
