With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features, the nXDS dry scroll pump is the best performing pump in its class.
The nXDS pumps use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry but also protecting the bearing from any process gases

nXDS improves on the original XDS 5 and 10 pump technology by offering an increased range of pumping speeds, combined with lower ultimate pressures, low power consumption and reduced noise. The gas ballast allows for the pumping of condensable vapors, including water, solvents, dilute acids and bases. nXDS pumps feature the very latest in tip seal technology, giving a significantly longer life between tip seal changes.

MSE Supplies is an authorized distributor of Edwards vacuum pumps.
