nXDS10i Scroll Pumps

Product description: nXDS10i Scroll Pumps

Product introduction

nXDS improves on the original XDS pump technology by offering increased pumping speeds, combined with lower ultimate pressures, low power consumption and reduced noise. The gas ballast allows for pumping of condensable vapours, 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.

nXDS-C has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications involving corrosive substances. This chemically resistant version is fitted with Chemraz® internal valves and stainless steel fittings.

nXDS-R has the gas ballast blanked off so it cannot be accidently opened. This is useful for applications such as rare gas recirculation or gas recovery.
