Hydraulic separators or compensators are able to make each pump or circulator work exclusively for its circuit.
Hydraulic separators therefore make it possible to avoid actions of mutual disturbance between the pumps that work for different circuits: actions that occur very often in traditional systems and can:
to make the pumps "burn", forcing them to work out of range;
"Stealing" motive power from the pumps themselves, making them unable to provide the required performance;
generate eddy currents that keep the terminals warm even when the pumps are stopped; operate the plants in conditions different from those planned and different from the optimal ones.
