This recirculation pump doesn’t need external cooling

Early this month, this company launched 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 that separates the pump set’s hot operating section from the air-cooled mechanical seal chamber. — KSB AG, Frankenthal, Germany
