EXAMPLE:
For a ∆T 20K, of a MODULEX 900, the maximum
water ow rate required is 36,289 l/h.
The graph of the boiler pressure drops shows that
the pump must ensure a head of at least 1.6 m/H

NOTE:
It is always advisable to use a hydraulic separator (*) between
the boiler circuit and the system.

2.4.2 - DETERMINATION OF THE PRIMARY CIRCUIT PUMP OR BOILER PUMP
The pumps must be determined by the installer
or designer according to the boiler and sys-
tem data.
The boiler pump must have head that is able to ensure the
pump's ow rates according to the circuit's ∆t.
The pump is not an integral part of the boiler.
It is recommended to select a pump with a ow rate
and head of approximately 2/3 of its characteristic
curve.
