[Refurbished] Edwards E2M0.7 Vacuum Pump, Dual Stage, Rotary Vane Pump, Hydrocarbon Elite Z oil, 200-230 VAC, A37141919

The Edwards Vacuum E2M 0.7 pumps are two-stage, direct drive, sliding vane pumps. The E2M0.7 pump is oil-sealed and designed for reliable, long-term operation. The pump is a free-standing unit. The drive is provided through a coupling by a single-phase motor.

The motor of this rotary vane vacuum pump is totally enclosed and is cooled by the motor-cooling fan which directs air along the motor fins. The motors are fitted with a thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. The thermal overload device has an automatic reset; when the motor cools down, the device resets and the motor will restart.

An oil pressure system 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 gasballast valve is open.

You can inspect the level and condition of oil in the oil box reservoir through a sight-glass. An oil filler-plug is fitted to the top of the oil box. An oil drain-plug is fitted at the bottom of the oil box. The pump has a carrying handle, inlet-port, outlet nozzle and gas-ballast control. The pump is mounted on a steel baseplate on rubber pads.
