XDS10C 115/230V, 1-ph, set to 230V for Europe



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-C range are designed for pumping condensable vapors and use materials selected for a wide range of laboratory wet chemistry applications.
A suitable electrical supply cable for your country should be ordered with this product.


Scroll pumps use intermeshing fixed and orbital scrolls to form non-contacting, crescent shaped gas pockets that are continuously compressed by the orbiting action. This means that, unlike oil-sealed rotary pumps, there is no sealant or lubricant required in the swept volume of the pump.
On the C-model (corrosion resistant) pumps, the turbine parts are protected from corrosion by a special coating. The pump may be further protected by purging with an inert gas; this will protect the bearings and motor from chemical corrosion.
