KSB has launched their Etanorm SYT pump series in the Indian market that are latest generation of single-stage volute casing pumps. These pumps have been specially developed for applications in modern heat transfer systems and hot water circulation.

The pump sets handle hot water as well as mineral oil based thermal fluids and synthetic thermal oils at tempera¬tures of up to 350 degrees Celsius. They are particularly suited for the rough conditions experienced in heat transfer systems and the stable rib design with reinforced bearings make them resistant to external forces. The increasing use of highly efficient synthetic oils, has made new developments essential in pump technology. Etanorm SYT incorporates technical innovations, like, a new vent design through which gases can be reliably removed during operation. For very critical fluids a variant with double mechanical seal has been introduced. Customers may choose between carbon (standard) or SiC plain bearings.

The pumps are hydraulically optimised and highly energy-efficient. They are supplied with an impeller diameter individually matched to the duty point of the actual system. By selecting the best impeller diameter and pump size from the large range on offer, an ideal combination can be found for the majority of duty points. This allows economical pump operation with the pump always running at or near its best efficiency point.
