Rotary Vane Refurbished Mechanical Vacuum Pump, Edwards E2M18

The E2M18 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. The drive is provided through a flexible coupling by a single-phase or three-phase (four-pole) motor.

The motors are totally enclosed and are cooled by the motor-cooling fan that directs air along the motor fins.
