Edwards E2M40 and E2M80 Rotary Vane Pumps
Edwards E2M series two stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapor. These direct drive rotary vane pumps are inherently compact and vibration free, and with their finger-proof fan and coupling housings they offer excellent operator protection.
Reliable system protection devices
Every pump has protection devices to prevent oil and air suck-back into the vacuum system if the pump stops while under vacuum. A variety of protection devices are used, depending on the pump size and cost, but emphasis is always placed on reliability and simplicity. When you use gas ballast on some of the pumps, you must use a solenoid operated gas ballast control valve to prevent air suck-back.
Positive Pressure Oil Lubrication
The EM pumps incorporate a well proven positive pressure oil lubrication system which as been developed by Edwards to ensure correct lubrication in all duty modes and particularly to prevent oil starvation with high gas loads.
An integral oil pump ensures that a more than adequate oil flow is pumped throughout the stator/rotor assembly at all times.
This oil lubrication system means that the level of oil in the reservoir is less critical than with other pump designs. All pumps can operate with oil levels as low as 50-70 of the maximum. A full length, easily visible oil level sight glass allows you to conveniently monitor the oil level.
Gas Ballast Facility
The EM pumps have a gas ballast valve. The valve is used to introduce a suitable gas into the stator during the compression stage: this prevents condensation of vapors inside the pump, dilutes and ejects corrosive gases and purges the oil of gases and vapors. Therefore, the use of gas ballast reduces oil degradation and pump corrosion.
Low Noise Levels
The EM pumps maintain Edwards’s reputation for quiet operation pumps with a typical noise level of 65dB(A).
