2BE3 and P2620Liquid Ring Vacuum Pumps and CompressorsNASH 2BE3 and NASH P2620: A Wide Application RangeNASH 2BE3 and NASH P2620:Reliable and EfficientThe liquid ring vacuum pumps and compressors of the NASH2BE3 and NASH P2620 series manufactured by Gardner DenverNash meet the rigorous needs of such industries as pulp andpaper, mining, geothermal, sugar, chemical process industries,and many others.Each model of the NASH 2BE3 and NASH P2620 series pumpsand compressors is equipped with an industry proven polyiso-prene-lined pump casing to help protect it against corrosionand erosion. The unique inlet and discharge configuration ofeach pump offers flexibility in piping and the top dischargecapability of the NASH 2BE3 models eliminates the need for atrench and minimizes floorspace. Each pump is 100% factoryperformance tested prior to shipment and is backed by a twoyear warranty against materials and workmanship.NASH P2620NASH 2BE3Process industriesPulp and paper industryMining IndustryNASH 2BE3 and NASH P2620: Superior PerformanceCFM 0 5 000 10 000 15 000 20 000 25 000m3/h 0 8 500 17 000 25 500 34 000 42 500 Capacity RangeP26202BE3 722BE3 672BE3 622BE3 602BE3 522BE3 502BE3 422BE3 402BE3 322BE3 30AlternateDischargeInletAlternate DischargeInletNASH 2BE3 NASH P2620DischargeDischargeAlternateInletPump Model A1 A2 B C D ESuction Flange /InletDischarge Flange /OutletP2620 1694300802030792005369009.825016 in.

The advantage of thisis significant, because it allows the use of fewer vacuumpumps–which saves space and installation costs. Quiet operation and easy maintenanceDespite their size and capacity, the NASH 2BE3 and NASHP2620 series pumps are amazingly quiet during operation.Sound levels of 72 to 85 dBa (measured at a distance of1 meter (3.3 ft) from the source) have been recorded foreven the largest of the pump models. Internal inspectionsare easily performed either through large inspection portslocated in the pump heads or through unused dischargeconnections. No dismantling of the pump is required.Robust, reliable and readyBecause the internal components rotate without makingcontact, liquid ring vacuum pumps are practically wear andmaintenance free. The standard polyisoprene lining on thepump body resists aggressive process gases and liquids toprovide exceptional corrosion resistance. The polyisoprenelining also saves you energy. Tests have shown that, overtheir lifetimes, pumps with our polyisoprene liningconsume less energy than the equivalent unlined pump.For added corrosion resistance, stainless steel internalcomponents are available in certain models. Double-rowtapered roller bearings extend pump life in both gear anddirect drive applications. Installation flexibilityDue to the design of the pump heads, the NASH 2BE3 andNASH P2620 models offer many options for connectingboth the inlet and discharge piping in order to simplifyinstallation in both new facilities or existing facilities whereheadroom and space is limited.Self-recirculation capability The NASH 2BE3 models help minimize water consumptionthrough their ability to internally recirculate seal water –without the need for circulating pumps or externalcontrols. The design of the internals also allows the pumpto draw water from an atmospheric tank without an exter-nal pumping source, eliminating the need for expensivepumps and control systems.2BV Compact liquid ring vacuum pumps built for serious cost savings Use up to 50 percent less water than other liquid ring pumpsMonoblock and pedestal designs availableCapacity of 4 to 350 CFM with vacuum to 29+’’ HgVCapacity of 7 to 595 m3/h with vacuum to 33 mbar absTC/TCMGAROCompressorsVectraSizes range from one-inch (25 mm) to 78-inch (2 meters) inletsCapacities range from 20 CFM to 20,000 CFMCapacities range from 34 m3/h to 34,000 m3/hMulti-stage system pressures as low as 0.001 HgAIntegral 2 stage liquid ring pumps with improved performance at vacuum levels down to 0.8’’ HgA / 27 mbar absDesigned to handle large amounts of liquid carryover without difficultyCapacity of 100 to 2,200 CFM with vacuum to 0.8’’ HgACapacity of 170 to 3,740 m3/h with vacuum to 27 mbar absLiquid ring vacuum pumps and compressors Available in feature rich budget designs (XL or GL)Designed to handle high back pressure requirementsCapacity of 115 to 2,860 CFM with vacuum to 29’’ HgVCapacity of 195 to 4,860 m3/h with vacuum to 31 mbar absHighly rugged and reliable compressors that can handle highly toxic, explosive and corrosive gasesSpecifically developed for applications such as flare-gas, chlorine and Vinyl Chlorine Monomer (VCM) recoveryCapacity of 2,200 SCFM with pressure to 200 PSIGCapacity of 100 to 3,400 m3/h with pressure to 15 bar absSingle and two stage models availableSteam JetEjectorOrder-No.: LRP:B-PB106-A1-EN©2006 All Rights ReservedGardner DenverLiquid Ring Pump Division9 Trefoil DriveTrumbull, CT 06611 U.S.A.phone: 1 800 553 NASH+ 1 203 459 3900fax: + 1 203 459 3988nash@gardnerdenver.comGardnerDenverNash.comOther NASH ProductsGardner Denver Nash is a division of Gardner Denver, Inc.
