General Description:

The E2M28 pump is a two-stage, direct drive, sliding vane pumps. The pump is oil-sealed and designed for reliable, long-term operation in both laboratory and industrial environments. The pump is a free-standing unit. The drive is provided through a flexible coupling by a three-phase (four pole) motor.

The motor is totally enclosed and are cooled by the motor-cooling fan which directs air along the motor fins.
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 air 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 gravity oil drain.

The pump has an inlet-port, outlet nozzle and gas-ballast control. The pump is mounted on an aluminium alloy baseplate.

To pump high vapour loads, gas-ballast is delivered into the pump to prevent condensation of the vapour carried by the pumped gases. Air (or another gas) can be introduced into the low vacuum stage through the gas-ballast control. The gas-ballast control is a multi-turn valve which you can adjust, as required, between closed and fully open.
