You can find traditional Edwards XDS pumps for sale on the LabX marketplace. Edwards now produces a new nXDS model that offers increased pumping speeds and lower ultimate pressures, lower power consumption and lower noise. These scroll pumps are an alternate option to rotary vane pumps where oil free pumping is desirable. If you are in the market, find the pump you need below and contact sellers for a price quote.
XDS pumps are an innovative design:
A bearing shield isolates 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.
An 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.
