Edwards E2M28 Two Stage Rotary Vane Pump, PFPE 200-220/380-415 V, 3-ph, 50 Hz or 200-230/460 V, 3-ph, 60 Hz IE2 A37341940

The EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - has become the industry standard laboratory and light industrial applications. 
The E2M28 pump is a two-stage, direct drive, sliding vane pump. The pump is oil sealed and designed for reliable, long-term operation in both laboratory and industrial environments. 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 exhaust flanges rather than the Nozzle that is supplied as standard with hydrocarbon pumps.

Fomblin® must be purchased separately for PFPE pumps.
