Nash - Model 2BV5 - Monoblock Liquid Ring Pump - Brochure

2BE5Liquid Ring Vacuum Pumpsand CompressorsAn upgrade of Nash's 2BE3 and 2BE4 vacuum pump series, the 2BE5 series offers capacities ranging from 1,500 to 19,000 CFM (2,500 to 33,000 m³/hr).This is achieved by modifications to the shaft bearings and through optimization of the port plates and the impeller. Improvements to internal flow channeling reduce the energy requirements by 6 to 8%. Optimization of the shaft bearings increases pump flexibility in the event of operational malfunctions and, ensures better lubrication, which extends the service life. An optional connection for rinsing the housing is also available. This feature improves cleaning and the service life. to 100 mbar abs./Vacuum Range to 3 in Hg abs Single, double (on request), Mechanical Seals stuffing boxDifferential pressure ~ 1.2 bar / 17.4 psicapability Compressor pressure > 2 bar abs. / 15 psig Ductile iron, stainless steel, Construction material combination of both materialsBasic Specifications2BE5 602BE5 502BE5 40CFM 0 5000 100003m /h 0 8500 170002BE5 30NASH 2BE5 Benefits include:• improved efficiency• higher vacuum levels• built-in ECO-FLO™ water saving technology with patent pending gas scavenging• drop in replacement for 2BE3 and 2BE4• removable bearing brackets for easier maintenance• improved sealing due to bolted casing joints• elimination of tie rods• polyisoprene liningNASH - Division of Gardner Denverphone: +1 800 553 NASH ·+1 724 239 1500 · fax: +1 724 239 1503 · email: nash@gardnerdenver.com GDNash.com© 2014 All Rights Reserved2BE5Liquid Ring Vacuum Pumpsand CompressorsDesigned to operate in demanding environments like the paper, power, mining and chemical process industries, these pumps offer durability and reliability at a low cost of operation. Each model is equipped with an application-proven polyisoprene-lined body for added corrosion & erosion resistance.The unique inlet configuration allows for both top and side inlet arrangements to accommodate low headroom installations. In installations where space is limited, the top discharge capability of the 2BE5 allows the use of a top mounted discharge separator that saves floor space and eliminates the need for a trench.All dimensions are approximateDimensionsmm in blue Pump A1 A2 B C D E Inlet Outlet 65.4 73.8 38.2 35.6 18.7 4.3 6 in.

When equipped with a center shroud, split vacuum operation up to 12 in. Hg (400 millibar) differential can be achieved. Large inspection ports allow easy access to pump internals for inspection and maintenance.For more aggressive applications, stainless steel, stainless steel clad and epoxy coated components are available.2A1A BECDInletOutletNASH - Division of Gardner Denverphone: +1 800 553 NASH ·+1 724 239 1500 · fax: +1 724 239 1503 · email: nash@gardnerdenver.com GDNash.com© 2014 All Rights Reserved
