Description
EDWARDS E2M28 ROTARY VACUUM PUMP 220-240V 50HZ Dual Stage A37315903. The E2M28 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 single-phase motors have a thermal overload device. Product Overview The Edwards E2M28 Rotary Vane 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 E2M28 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. The 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 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 aluminum alloy baseplate on rubber pads.
