Refurbished Edwards E2M1.5 Vacuum Pump, Dual Stage, Rotary Vane Pump, Hydrocarbon Elite Z oil, 100-120VAC, A37132902
The E2M1.5 pumps are two-stage, direct drive, sliding vane pumps. The 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 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.
Unit is fully rebuilt and comes with a FULL 6-MONTH WARRANTY!
