KSB: New impeller combines reliability and efficiency

Monday, March 14th, 2016 von admin

KSB_DFmax-Laufrad_01The newly developed free-flow impeller for waste water pumps will be the trade fair highlight showcased by KSB at this year’s Ifat in Munich. The F-max impeller now incorporates different distances between its blades, which are arranged in groups with two small and two large distances. Thanks to this asymmetrical blade arrangement, the F-max offers impressively wide free passages ensuring that even larger rigid solids pass easily and are reliably handled by the pump.

A further focus for KSB’s engineers when designing the blades was their ability to create a swirl in the hub area. This swirling effect shifts fibres away from the impeller hub and transports them to the outside.

Mechanical Solutions Inc. (MSI), headquartered in Whippany, New Jersey, specializes in fluid machinery design, fluid dynamic analysis, mechanical design and analysis. In the energy industry, MSI focuses on analysis, testing and troubleshooting of all kinds of rotating, reciprocating and turbomachinery, using sophisticated analysis and testing tools. These specialists are using Star-CCM, an industry-leading simulation package to tackle design challenges in water pumps.

Major design challenges of water pumps include the unsteadiness of the flow, cavitation and rotating machinery. Star-CCM offers features that can successfully tackle these difficult physics while offering a streamlined, robust numerical design process. Geometry generation, meshing, solving, post-processing and optimization can all be done in an efficient workflow.

Features like the unsteady flow solver, unsteady cavitation model, Rigid Body Motion (RBM) for rotating domains, automated unstructured meshing for complex geometry and parallel processing capability offer the ability to explore multiple water pump designs in an economical manner. The system allows designers to easily predict pump performance at design and off-design points and avoid damaging effects of cavitation and erosion.

KSB: New generation of the world’s best-selling standardised water pump

Tuesday, February 19th, 2013 von admin

Global Pump, Etanorm,

Actually KSB is launching the latest generation of its Etanorm series, which has been produced non-stop since 1936. The type series of the new generation comprises 43 pump sizes, which can be driven by either 2-pole or 4-pole motors. The selection chart has been extended by additional pump sizes, so that sizes can be selected even closer to the best efficiency point. The Eta type series is the global best-seller among standardised water pumps. Since 1936 more than 1.5 million Eta pumps have been produced worldwide.
