Small Pumps and Pumping Systems 1 Page 2 To meet the diverse needs of applications ranging from analytical instrumentation, wet chemistry, R & D to light industrial, Edwards offers a comprehensive range of different pumping technologies. Refer to the application and accessory guide to select pumps and accessories for your application. Oil Free Scroll Pumps Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The innovative XDS pumps in particular use a bearing shield to isolate the vacuum environment from all forms of lubricant not only making them...

Small Pumps: Application and Accessory Information Use the information in the list below to select the best pump and accessories for your application. The information is given as a guide only; the optimum set-up may depend on your specific method of operation. Note that you need to buy the accessories separately, unless otherwise stated. ATEX and Flammable Gases The following standard pump models have an internal ATEX classification of II 3 G c IIB T4: • • • • Load Locks, Fume Hoods and Glove Boxes Recommended pump: nXDS/XDS or Rotary pumps. Suggested accessories for rotary pumps: Mist filter,...

Small Pumps and Accessories: Frequently Asked Questions 1 Page 4 Oil Mist Question: What accessory do I use to trap oil mist (which all oil sealed pumps emit during pump down or with gas ballast)? Answer: To meet regulations and preserve pump oil, fit a recommended Edwards oil mist filter (EMF) to the pump outlet, and connect the exhaust to an exhaust line. Question: If I operate an RV pump continuously or with high inlet pressure, what accessories do I need? Answer: Fit an Edwards mist filter (EMF) and a gas ballast oil return (GBOR) kit. Then the pump can be operated with the mode switch open...

nXDS6i Scroll Pump The nXDS6i is the next generation in completely oil free, dry scroll pumps and replaces the XDS5. 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 vapours 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....
