Product: Series e-HSC

Description: Featuring advanced hydraulics for powerful performance and best-in-class efficiency, this product has a compact design to aid in installation and maintenance. The line is suitable for commercial buildings such as hospitals, shopping centers and malls, hotels and resorts, sports arenas, office buildings, and airports, or for systems that require chillers, cooling towers, distributive pumping, district heating and cooling, primary and secondary pumping, or process application. A new volute design — either single- or dual-volute, based on the hydraulic constraints — extends bearing life and reduces shaft deflection within the preferred operating range (POR) of the pump, from 70 to 120 percent of the best efficiency point. When running within the POR of the e-HSC, bearing life expectancy will exceed 100,000 hours (L10). The product is designed with large “efficiency islands” within the POR as well, which help to increase efficiency at partial loads using variable-frequency drives.
