Hot Water Recirculation Pump

摘要

KSB offers 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 temp of up to 400°C without any additional cooling devices, and is designed for pressure classes of up to PN 40.. A fan impeller fitted at the pump shaft end generates a continuous flow of air between the large cooling fins surrounding the mechanical seal chamber.
