Gas ballast control knob for XDS and nXDS pumps

Edwards nXDS10ic “Non-Flammable and Non-Toxic Gases”
Edwards nXDS Vacuum Gas Ballast Control Knob, Fits All nXDS Dry Scroll Vacuum Pumps.
No atmosphere to vacuum shaft seals means bearing are completely isolated, which prevents process attack and means the bearings run cooler and last longer

We also do Minor and Major Repairs on ALL Edwards Dry Scroll Pumps.

Max pressure of 1000 psi (69 bar)

Works With Edwards nXDs Series Dry Scroll Vacuum Pumps:
The Edwards Vacuum nXDS series is the next generation in completely oil free, dry scroll pumps and replaces the XDS series. nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise. Gas ballast allows for pumping of condensable vapors including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimized pumping performance globally. nXDS pumps are designed to be completely field serviceable.

Edwards nXDS10i
These Edwards nXDS gas ballast control knobs are used with the nXDS-i “standard” and nXDS-ic “chemical resistant” series dry scroll vacuum pumps. The gas ballast is a control valve that intentional introduces a small room-air leak into the second stage of the vacuum pump, producing a positive flow throughput, and sweeping out vapors from volatile compounds, such as, water and others. When pumping volatile compounds, like water vapor, they are compressed inside the pump and condense into a liquid. When condensation happens the ultimate vacuum pressure of the vacuum pump is now limited to the vapor pressure of the volatile contaminating compound, for example, the room temperature vapor pressure of water is around 23.8 Torr. The gas ballast should be opened while the pump is warmed up to help evaporate and sweep out the volatile vapors. It is often good to leave the pump running overnight with the gas ballast open to rid it of volatile compounds. The gas ballast should not be used when pumping flammable, as the gas ballast introduces air which contains oxygen. The gas ballast should also not be used when pumping toxic compounds, as the gas ballast introduces a leak into the room air, if the pump is turned off, a small amounts of vapors from inside the pump could potentially leak out through the gas ballast port into the room air. These replacement Edwards nXDS gas ballast control knobs have part number A735-01-759.
