The EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - has become the industry standard laboratory and light industrialapplications.
The E2M28 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 pump is a freestanding unit with the drive provided through a flexible coupling by either a single-phase or three-phase (four-pole) motor.

Technology

 

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 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 two oil drain-plugs to allow either gravity oil drain or pressure oil drain.
