Hydraulic separator DN 25 (1")
Description
Hydraulic separators are used when there are simultaneously one or more heat
generator circuits/primary circuits with an own pump and one or more
consumer/secondary circuits with a distribution pump in an installation. The
hydraulic separator causes a hydraulic separation of the connected circuits. It is
thus possible to make the connected primary and secondary circuits work
independently in terms of the hydraulics. The flow in one circuit does not cause a
flow in the other circuit when the pressure drop in the hydraulic separator is
insignificant.
When a hydraulic separator is used, each circuit (the primary and the secondary
one) must be equipped with a pump. Thus, a heat generation 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 figures on the adjoining side show three possible conditions of hydraulic
stability.
