Overview
Technology
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¢Ûªs reputation for quiet operation pumps with a typical noise level of 70 dB(A).
Pumping Systems
The EM pumps, with suitable accessories, can partner a variety of other types of pump in vacuum systems for industry and for research. A special feature of the E2M80 is the central vacuum inlet which enables you to fit a mechanical booster pump with a minimum overhang, to create compact combination pumping systems.
Easy Maintenance
The advanced lubrication system allows the EM pumps to work with wide oil level tolerances, which reduce the need to top-up the oil.
All EM pumps are constructed with internal dowels, which reduce the need for skilled setting of tolerances, when the pump is dismantled. The pumps are designed so that all key components are easily accessible. The exhaust valve seals and oil distributor seals are exposed after the top cover is removed. The shaft seal can be replaced quickly without stripping down the pump.
