Wilo Para KSL/7-50/IPWM1 High-Efficiency Circulation Pump for Combi Boilers and Heating Systems

The Wilo Para KSL/7-50/IPWM1 circulation pump is designed to ensure balanced, continuous and efficient circulation of water in the pipework of combi boilers and heating systems. Thanks to the iPWM control mode, it automatically adjusts speed and performance according to signals from the boiler PCB.

Its high-efficiency motor provides low energy consumption while improving the overall efficiency of the heating system. Thanks to its quiet operation, it is a reliable choice in residential combi boiler applications.

It is an original Wilo circulation pump widely used in service work for insufficient heating, radiators heating up slowly, circulation problems or pump failures.
