Edwards Vacuum Pumps

Edwards vacuum scroll pumps    

The XDS pumps are an innovative new design which use a patented bearing shield to isolate the vacuum environment from all forms of lubricant, not only making it totally dry, but hermetically sealed. The shield also protects the bearing from any process vapors.

Adjustable gas ballast allows vapor to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps.

The XDS pumps are designed for pumping condensable vapors and use materials selected for a wide range of laboratory wet chemistry applications.

Edwards EM Series (small) Rotary Vane pumps

The EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapor - has become the industry standard for industry and laboratory applications.

The E2M28 pump is a two-stage, direct drive, sliding vane pump. The pump is oil sealed and designed for reliable, long-term operation in both laboratory and industrial environments. 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.

Edwards vacuum RV Series Oil pumps

To meet demands for high throughputs with high ultimate vacuum, Edwards have developed a new concept in vacuum pumps - the world's first dual-mode vacuum pump.

This allows the user to easily configure the unit to pump very high gas loads and achieve excellent vacuum - from a single pump.

This is matched by design features such as a fully-featured Edwards motor and a fast-acting inlet valve to seal the pump for suck-back protection. Also, Edwards research into drive train and motor noise means the RV series delivers a high performance pump and broad performance envelope that's quiet and easy to maintain.

Turbomolecular Pumps

The range of EXT turbo molecular and compound molecular pumps and EXC Controllers uses state-of-the-art technology to provide reliable, hydrocarbon-free, high and ultra high vacuum.

A turbo molecular pump (TMP) is a multi-stage axial-flow turbine in which high speed rotating blades provide compression by increasing the probability of gas molecules moving in the pumping direction. The turbo molecular pump is optimized for molecular flow conditions and requires a suitably sized two stage rotary vane pump or an oil free scroll pump to exhaust to atmosphere.
