3 Function

The hydraulic separator allows to equalize
the pressure and the flow rate in heating
installations with one (or more) pumps in
the boiler circuit and one or more pumps in
the consumer circuits, without that the
circuits hydraulically affect each other -
when the pressure loss in the hydraulic
separator is insignificant.
When a hydraulic separator is used, each
circuit (the primary and the secondary
circuit) must be equipped with a pump!
Thus, a boiler circuit/primary circuit can be
provided with constant throughput and a
consumer circuit/secondary circuit can be
provided with variable flow. These are the
typical functioning conditions for modern
heating and air conditioning systems.
The example on the left side shows three
possible conditions of hydraulic stability.
