Edwards E2M18 Dual Stage Rotary Vane Pump, Three Phase, 200-230/380-415 V, 50 Hz or 200-230/460 V, 60 Hz, A36310940
Edwards E2M18 Overview:
The Edwards E2M18 Rotary Vane Pump is a vacuum pump that has a pressurized 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.
The EM Vacuum Pump Series range of oil‑sealed 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 single‑phase or three‑phase (four pole) motor.

- Research and development
- Rotary, centrifugal evaporators
- Scanning electron microscopes - SEM
- SEM/FIB (Ion beam repair)
- Solvent recovery
- Surface science instruments
- Turbomolecular backing pumps
- TV manufacturing / light bulb manufacturer
Edwards E2M 18 Dual Stage Rotary Vane Pump Features:
- 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.
- Full height O ring sealed oil sight glass for easy checking of oil level and condition.
- Large sight glass and operating oil range.
- IE3 energy efficient 3 phase motor used with E2M28.
