Overview 

 

Edwards E2M175 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 vapour. 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.
This pump is suitable for most duties and is safe to handle non-flammable gases and vapours within the normal operating parameters of the pump.
Supplied with Ultragrade 70 Oil. Fomblin® must be purchased separately for PFPE prepared pumps E2M40FX, E2M80FX, and E2M175FX.

 

 

Features and Benefits of Edwards E2M175




    • Advanced pressurised oil circuit to give effective lubrication even under high gas loads
    • When the pump is switched off, the spring loaded distributor valve provides oil and air suck-back protection
    • Gas Ballast control to assist in handling high water vapour loads
    • Industrial roller bearings on drive shaft for ultimate reliability and long, trouble free life
    • Full height oil sight glass for easy checking of oil level and condition
    • Easy change oil filter, with oil filter condition gauge on larger models
    • Central inlet port to allow easy mounting of mechanical booster pump if required
    • Easy to maintain, with convenient service kits and international customer support.
    • A wide range of accessories to match your application needs
    • The pumps and accessories can be supplied either as individual components or as fully systemised, factory-tested combinations.

Technology


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 E2M175 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 75 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 E2M175S 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.
