KSB Etanorm series New versions of an old favourite offer improved efficiencyEngineering
Mississauga, ON, April 2013 – Responding to a worldwide need to conserve valuable energy resources, KSB has introduced a new, efficiency-optimized generation of its popular Etanorm family of centrifugal pumps.
KSB’s engineering team began their quest for improved efficiency by refining the hydraulic contours inside the pump through a combination of advanced computational fluid dynamics (CFD) analysis and laboratory testing. This effort also resulted in improvements to intake suction and NPSH, with the result that cavitation under difficult operating conditions is reduced and pumps will run more smoothly and reliably. Finite-element stress analysis was used to strengthen pump casings so that the new models can withstand higher mechanical loads from piping systems. Other refinements that improve durability and maintainability include enlarged space around seals and more effective gaskets.
KSB recognizes that one of the most effective ways of ensuring economical pump operations is to closely match pump capabilities to application requirements. For this reason, Etanorm pumps come in 43 sizes. Special alloys are available for use with aggressive fluids, oils etc. The Eta series is the global best-seller among standardized water pumps. Since 1936 more than 1.5 million Eta pumps have been placed into service worldwide.
