• 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

Clean and Overhaul

Regular cleaning of the vacuum pump to remove process deposits and replacement of the seals to prevent oil and vacuum leaks is essential to maintaining high performance of the product, as well as a clean, safe operating environment. A clean and overhaul kit contains all the parts needed for routine cleaning of your pump

Accessories

If accessories are fitted to your pump, they too will require regular checks and maintenance. A blocked dust filter, for example, can significantly reduce the efficiency of a pump.

Blade (vane) replacement

Blades (vanes) on a rotary pump will wear during normal operation. Edwards recommends replacing them every 30,000 hours (40 months), or as your process conditions dictate. A blade kit contains a full set of blades and typically is used in conjunction with a clean and overhaul kit.

Act responsibly and safely

Edwards cares about the health and safety of people and the environment. Please remember to dispose of used or contaminated oil, cleaning solutions and components responsibly and safely.

Technology

The Edwards E2M18 Vacuum Pump is a single stage oil sealed rotary vane pump which 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.
