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
- as long as 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 adjacent figures illustrate three
possible conditions of hydraulic stability.
