Question: How is a circulator pump regulated using differential pressure regulation?

The pump reacts to changing volume flows in the system by changing the speed. When thermostat valves and control valves are opening, the volume flow rises and the pump increases the speed. When valves are closing, the pump reduces the speed. This also reduces power consumption. In order for this type of control to function reliably, it is necessary to perform a hydraulic balancing of the pipe network.
