Overview                                                                                                                                      

The Edwards nXDS dry scroll rotary pumps provide 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. 

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 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.

The nXDS model is offered in three variations: The standard version (Just "i" o n the end) , the "C" version and the "R" version. Now if you are not sure about the "C" or "R" versions, just order the standard "i"version i.e. The model part number with just the "i" on the end. Here is a summary of the "C" and "R' versions: 

nXDS-C has been modified so that it is more suitable for use on vapor 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 accidentally opened. This is useful for applications such as rare gas recirculation or gas recovery.
