HPK-S, HPK-SY, and HPK-Y hot water circulation pumps are mainly used for transporting hot water circulation or organic heat 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, and the system pressure is not high. HPK pumps are single-stage single suction horizontal hot water centrifugal pumps, with a horizontal suspension, radial part, rear door, and center support structure, suitable for transporting high-temperature and clean media. The product complies with GB5656-1994 "Technical Conditions for Centrifugal Pumps (Class II)" and GB3215 "General Technical Conditions for Centrifugal Pumps Used in Refineries, Chemical and Petrochemical Processes"

1. Efficient and energy-saving: CFD computational fluid dynamics is used to analyze and calculate the relationship between pressure distribution and velocity distribution inside the pump, optimize the flow channel design of the pump, ensure that the pump has an efficient hydraulic profile, and improve the efficiency of the pump. 2. High temperature resistant structure: The pump body adopts a central support method, which solves the problem of stress concentration caused by inconsistent thermal expansion of the pump unit under high temperature and changes in the center of the coupling when transporting high-temperature media. The pump bracket, pump cover, suspension body (bearing part), and machine seal cover all have cooling chambers, which can be cooled with cooling water or air at different temperatures.

3. Bearing: The bearing is equipped with cylindrical roller bearings and two angular contact bearings, lubricated with thin oil, which significantly improves the load-bearing capacity. Bearing design life

25000 hours.

4. Shaft seal: Optional soft packing seal and mechanical seal.

5. Coupling: Adopting elastic column end coupling, with high transmission accuracy.

6. Auxiliary piping: configured according to API 610 8th edition requirements.

7. Pressure bearing: The design pressure is 4.0MPa, with high pressure bearing capacity.
