Overview

 

The EM range of oil-sealed rotary pumps - renowned fortheir 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 E2M18 pump is a two-stage, direct drive, sliding vane pump. The pump is oil sealed and designed for reliable, long-term operation. 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.

 

Features and Benefits

    • The pump is designed for reliable, long-term operation.
    • Thermal overload device prevents overheating (single phase only).
    • 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.
    • Pressure die cast oil box with integral oil seals prevents oil leaks
    • Gas ballast valve for large water vapour handling capacity.
    • Externally approved to EN61010, CSA, C22.2 and UL61010.
    • Large O-ring sealed oil sight glass allows oil condition and level to be easily inspected.



Technology


This is a single stage oil sealed rotary vane pump which has a pressurised oil system that 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 an oil drain-plug to allow either gravity oil drain or pressure oil drain.
