Edwards E2M18 Dual Stage Rotary Vane Pump, Single Phase, 115/200-230 V, 50/60 Hz, A36317984

The Edwards E2M18 Rotary Vane Pump is a vacuum pump that has a pressurized oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil suckback unless the gas ballast valve is open.

You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.

The EM Vacuum Pump Series 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 pump is a freestanding unit with the drive provided through a flexible coupling by either a single‑phase or three‑phase (four pole) motor.
