The HPk type hot water circulation pump adopts patented technology of low specific speed centrifugal pump, which is developed on the basis of absorbing and digesting advanced foreign technology, and has the characteristics of high efficiency, energy saving, and reliable operation. Suitable for the transportation of hot water circulation or organic exchange media in pipelines or closed circuits in metallurgy, power plants, textile, chemical, heating, and waste heat utilization systems. For pumps that transport heat exchange media, the medium and pump are at high temperatures, but the system pressure is not high. Transporting high-temperature water below 280 ° C without particles, with heat exchange medium ≤ 400 ° C. The HPK type hot water pump is made of cast steel, 304 stainless steel, and 316L stainless steel. Its rotor bearings are imported SKF bearings, which can meet the requirements of different customers and have good performance.
