• Pump for handling hot water and also organic or synthetic heat transfer fluids in piping or tank systems.
• Also Heating systems
• Forced circulation boilers
• Also District heating
• Heat transfer systems

HPK-L KSB Benefits

• Low temperature in the mechanical seal chamber; also no cooling water required thanks to air-cooled bearing bracket with heat barrier.
• Also Increased operating reliability of versions for heat transfer applications by an optional two mechanical seals preventing leakage.
• Higher efficiencies than the previous HPK-L model by continued development of the flow passage within the hydraulic system.
• Also Optimised venting of mechanical seal chamber by patented VenJet profile.
