Edwards XDS35i Oil-Free Dry Scroll Vacuum Pump, 100-240 VAC, 21.0 CFM. Edwards Part Number: A73001983. This Edwards XDS35i dry scroll roughing/backing pump has a pumping speed of 21.0 cfm (35.0 m3/hr), and an ultimate vacuum of 0.008 Torr (0.01 mbar). The pump has a KF-40 (NW40) inlet with inlet strainer, and a KF-25 (NW25) outlet port. It requires 100-240 VAC single phase power and has a C19 power connector. The XDS35i draws 10.6A@120 VAC (6.6A@240 VAC). The pump has a run/standby switch, a high/low voltage switch, an hour meter, and an onboard inverter which can be controlled remotely via its DB15 logic interface. This Edwards XDS35i dry scroll pump has part number A73001983. The Edwards XDS35i scroll pump has a patented bearing shield designed to isolate the vacuum environment from all forms of lubricant. This feature ensures that the bearing remains totally dry, as well as protecting it from any process gases. The adjustable gas ballast allows vapor to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps. This Edwards XDS35i pump is designed for pumping condensable vapors, and uses materials selected for compatibility in a wide range of laboratory applications.

Edwards XDS35iC Corrosive Version Oil-Free Dry Scroll Vacuum Pump NEW A73006983 This Edwards Corrosive Version (C) XDS35iC has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications using corrosive substances. The C version is fitted with Chemraz internal valve pads and stainless steel exhaust port. The XDS35iC Oil-Free Dry Scroll Vacuum Pump has a patented bearing shield designed to isolate the vacuum environment from all forms of lubricant. This feature ensures that the bearing remains totally dry, as well as protecting it from any process gases. The adjustable gas ballast allows vapor to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps.The XDS35iC is optimized for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar making it ideally suited for LCMS and ICPMS applications requiring a higher pumping speed than that offered by the XDS35i. Recent improvements in tip seal technology have lead to reduced tip seal wear therefore giving a longer time between service interventions. Pumping displacement for this pump is 25 CFM at 60hz. With the purchase price a manufacture warranty is included. Parts and accessories for this pump are available on this website.

Edwards XDS35i E Enhanced Oil-Free Dry Scroll Vacuum Pump With Gas Ballast. PN: A73003983 100-230 VAC 1 phase (With Gas Ballast) The XDS35iE Enhanced is being introduced to be sold alongside the existing XDS35i family of pumps. The Enhanced pump features patented double start and by pass valve technology to enable it to address applications beyond the operating envelope of the standard XDS35i pump (such as pumping down large chambers). This will open up more opportunities for our customers to benefit from XDS Scroll pump technology. For a quick history lesson, the XDS35i was launched in 2002 and continues to be very successful with over 20,000 pumps produced. The pump is well suited to many applications but evacuation of large chambers and regular cyclic duties have been beyond its typical operating envelope. We are delighted to say that the Enhanced pumps address this opportunity and will be offered in Standard, No Gas Ballast and Chemical versions to complement the current XDS35i family. The Enhanced pump versions (XDS35iE and XDS35iCE) are equipped with patented technology which prevents over-compression within the scroll mechanism at high operational pressure and large throughput applications. Twin by-pass valves release sufficiently compressed gas directly to the pump exhaust, increasing pump efficiency, lowering power consumption and enhancing pumping speed. Valve operation occurs at inlet pressures greater than 300mbar meaning the pump is tailored towards applications which dwell at higher pressure. The elimination of over-compression at high operational pressure, reduces power consumption and diminishes bearing loads, extending bearing life. Consequently, the E enhanced versions are capable of operation without limitations to the both the size of vacuum chamber, or the frequency of pump-down on cyclic duties. There is one note we want to bring to your attention. The pump modifications within the E Enhanced version have a small adverse effect on the ultimate vacuum achieved, however the pump has a larger tolerance to operating altitude and ambient temperature. There are details of this within the attached data sheet .pdf to the side of Downloads. Service Intervals are going to be very low, similar to the existing scroll pumps range.
