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.

KSB: Hot water recirculation pump without external cooling

Friday, May 23rd, 2014 von admin

KSB_HPK-L (2)Early in June 2014, KSB will launch a new generation of hot water recirculation pumps for large industrial heating systems as well as forced circulation boilers and district heating systems. The horizontal, radially split single-stage volute casing pumps feature a back pull-out design. Their ratings and dimensions comply with ISO 2858; with regard to handling hot water, organic or synthetic heat transfer fluids, they also meet the technical requirements of ISO 5199.  The HPK-L pump series, which comes in 49 different sizes, can be operated at temperatures of up to 400 °C without any additional cooling devices, and is designed for pressure classes of up to PN 40. This temperature resistance is achieved by means of a generously sized heat barrier which separates the pump set’s hot operating section from the air-cooled mechanical seal chamber.
