Edwards nXDS Ballast Blank-Off Adapter Kit, Converts Standard nXDS-i Pumps into The nXDS-ir Version. Edwards Vacuum Part Number PN: A735-01-806. These Edwards nXDS gas ballast blank adapters are for the nXDS dry scroll vacuum pumps. This adapter kit allows you to convert a standard nXDS-i pump into an nXDS-ir version. The nXDS-ir series pumps are designed for special applications, such as gas recirculation, rare gas pumping and recovery, or other applications where the dilution of the pumped gas is undesirable, or where sealing is integral to minimizing potential gas loss. These Edwards nXDS gas ballast blank adapters are often used to replace the standard gas ballast control knob, so that the gas ballast cannot be accidentally opened, the advantage is improved leak tightness at the ballast location. They have Edwards part number A735-01-806.Works With Edwards nXDs Series Dry Scroll Vacuum Pumps: Edwards nXDS6i Edwards nXDS10i Edwards nXDS15i Edwards nXDS20i Edwards nXDS6ic Edwards nXDS10ic Edwards nXDS15ic Edwards nXDS20ic

Edwards nXDS Dry Scroll Pump Gas Ballast Purge Adapter, Fits nXDS-i and nXDS-ic Dry Scroll Vacuum Pumps. Edwards Vacuum Part Number PN: A735-01-809. These Edwards nXDS gas ballast purge adapters may be fitted in place of the original gas ballast control knob and used to supply an inert purge gas, such as nitrogen. They are commonly used with the nXDS-i standard and nXDS-ic chemical resistant series dry scroll vacuum pumps. It is important to replace the gas ballast control knob with this purge gas adapter when you are using the nXDS pump on chemical applications, please read below. The gas ballast is a control valve, that intentionally 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 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 compounds, 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 amount of vapors from inside the pump could potentially leak out through the gas ballast port into the room air. These Edwards nXDS gas ballast purge adapters have part number A735-01-809.

Edwards nXDS Dry Scroll Vacuum Pump Tip Seal Kit, For Minor Rebuild Service, Fits All nXDS Series Pumps. Edwards Vacuum Part Number PN: A735-01-801. These Edwards nXDS series dry scroll pump tip seal kits are used when a minor rebuild service is required. This is typically needed 2-years after the pump is placed into service, often required between 12,000 and 16,000 operating hours. The pump will start to lose its ability to reach the lowest ultimate pressure as the tip seals become worn out. The base pressure for a new nXDS pump is often measured at 10 mTorr or less when evacating a good clean leak-tight vacuum chamber. If you notice that your base presure is now only getting to 25 mTorr then the tip seal will likely need to be replaced. Please see the instructions shown in the tip seal replacement manual in our Downloads section below.Works With All Edwards nXDs Series Dry Scroll Vacuum PumpsEdwards nXDS6i Edwards nXDS10i Edwards nXDS15i Edwards nXDS20i Edwards nXDS6ic Edwards nXDS10ic Edwards nXDS15ic Edwards nXDS20ic Edwards nXDS6ir Edwards nXDS10ir Edwards nXDS15ir Edwards nXDS20ir
