Overview

The EM range of oilsealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a singlephase or threephase (four pole) air cooled 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 after the pump stops. The pumping chambers are air-tight, so this arrangement also prevents 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.
