Operating principle
When a single system contains a primary production circuit, with its
own pump, and a secondary user circuit, with one or more distributions
pumps, operating conditions may arise in the system whereby the pumps
interact, creating abnormal variations in circuit flow rates and pressures.
The hydraulic separator creates a zone with a low pressure loss, which
enables the primary and secondary circuits connected to it to be
hydraulically independent of each other; the flow in one circuit does
not create a flow in the other if the pressure loss in the common
section is negligible.
In this case, the flow rate in the respective circuits depends
exclusively on the flow rate characteristics of the pumps,
preventing reciprocal influence caused by connection in series.
Therefore, using a device with these characteristics means that the flow
in the secondary circuit only circulates when the relevant pump is on,
permitting the system to meet the specific load requirements at that time.
Three possible hydraulic balance situations are shown below.
Gprimary = Gsecondary
Primary Secondary
Gp Gs

Gprimary > Gsecondary

Gprimary < Gsecondary

When the secondary pump is off, there is no circulation in the secondary
circuit; the whole flow rate produced by the primary pump is by-passed
through the separator.
With the hydraulic separator, it is therefore possible to have a primary
production circuit with a constant flow rate and a secondary distribution
circuit with a variable flow rate; these operating conditions are typical of
modern heating and cooling systems.
