Large Pumps and Pumping Systems8Page276IntroductionEdwards range of industrial dry pumps, oil sealed rotary pumps, oilsealed piston pumps and mechanical boosters are the mostcomprehensive available to the industrial user. Add our extensiverange of accessories and the pumps can be configured for a widerange of applications. The pumps and accessories can be suppliedeither as individual components or as fully systemized, factory testedcombinations.The range consists of:• GXS dry pumps• IDX dry pumps• Drystar ® 80 dry pumps• EM oil sealed rotary vane pumps• Stokes Microvac oil sealed piston pumps• EV oil sealed rotary vane pumps• EH, Stokes Vacuum 6" and HV booster pumpsGXS Dry PumpsEdwards, a pioneer in dry pumping technology, launches a newgeneration of dry pumps for industrial applications.Edwards has over 90 years of experience in harsh process vacuumapplications, including dust and process contaminants handling, withmore than 150,000 dry pumps installed worldwide.The GXS industrial dry screw pump incorporates innovative, patenteddesign features that establish a new standard in dry pumping.Fast - Dry pumping down to 5 x 10 -4 mbar / 3.7 x 10 -4 Torr ultimatevacuum (without purge)Robust - Reliable operation in harsh industrial applicationsCompact - Smaller footprint than pumps of similar capabilitiesEconomical - Affordable capital investment and low cost of ownershipEnvironmental - Smooth, quiet running with low power and utilitiesconsumptionIDX and Drystar ® 80 Dry PumpsThe Drystar ® 80 is based on the well proven Edwards reverse clawmechanism reaching a peak speed of 560 m 3 h -1 / 330 ft 3 min -1 . Thereverse claw mechanism results in short gas paths within theoperating mechanism, providing the ability to handle large amountsof dust and water vapour, when compared to oil sealed pumps,without deterioration of performance.The IDX 1000 and 1300 use the latest double ended screwtechnology to provide a peak speed of up to 1300 m 3 h -1 /767 ft 3 min -1 . Many features are patented and as with the GV rangeare able to handle large amounts of dust and water vapour with littleor no effect on performance.• Low cost of ownership in harsh conditions• High reliability – dry mechanism proven in 100,000 installations• Oil free mechanism – reduced maintenance• Higher dust and water vapour tolerance• Accessories to optimise pump performance to process variables• Fast pump down with Edwards hydrokinetic drive booster pumps.EM Oil Sealed Rotary PumpsEdwards rugged two stage mechanical oil sealed pumps areavailable in sizes from 40 - 275 m 3 h -1 / 30 - 206 ft 3 min -1 . They feature:• Advanced oil lubrication circuit• High reliability• Accessories to match your application needsStokes Microvac Oil Sealed Rotary Piston PumpsStokes Microvac oil sealed piston pumps are available in sizes255 - 1240 m 3 h -1 / 150 - 728 ft 3 min -1 . They feature:• Proven rugged robust design• Internal oil piping to eliminate potential leaks• Oil sight glass and flow indicator to provide easy monitoring of oillevel and flow• O-ring sealed covers to eliminate potential oil leaks• Integral gas ballast valveShop online at www.edwardsvacuum.com
