E2M18 / A36315903 Overview:
The Edwards E2M18 / A36315903 vacuum pumps are direct drive, sliding vane pumps. The E2M18 is a dual-stage vaccuum pump.
The Edwards E2M18 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 single-phase or three-phase (four pole) motor. The motors are totally enclosed and are cooled by the motor-cooling fan which directs air along the motor fins.
This pump has been rebuilt with Hydrocarbon oil.
The Edwards single-phase motors have 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. The single phase motors have an on/off switch.
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 gasballast 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. It also has an inlet-port, outlet nozzle and gas-ballast control. The pump is mounted on an aluminium alloy baseplate on rubber pads.
When you use the pump with high vapour throughputs, you should use the gas-ballast facility to prevent condensation of the vapours inside the pump. The condensates will contaminate the oil, will cause performance to deteriorate and may cause corrosion of the pump mechanism.
