7.2 Constant-pressure curve (CP1, CP2 or CP3)
Constant-pressure control adjusts the pump performance to the
actual flow rate demand in the system, but the pump performance
follows the selected performance curve, CP1, CP2 or CP3. See
fig. 22 where CP1 has been selected. For further information, see
section 8. Fault finding the product.
Fig. 22 Three constant-pressure curves/settings
The selection of the right constant-pressure setting depends on
the characteristics of the system in question and the actual flow
rate demand.
7.3 Constant curve (I, II or III)
At constant-curve operation, the pump runs at a constant speed,
independent of the actual flow rate demand in the system. The
pump performance follows the selected performance curve, I, II
or III. See fig. 23 where II has been selected. For further
information, see section 8. Fault finding the product.
