Factory setting: Intermediate proportional-pressure curve,
referred to as PP2.
7.1 Proportional-pressure curve (PP1, PP2 or PP3)
Proportional-pressure control adjusts the pump performance to
the actual flow rate demand in the system, but the pump
performance follows the selected performance curve, PP1, PP2
or PP3. See fig. 21 where PP2 has been selected. For further
information, see section 8. Fault finding the product.
Fig. 21 Three proportional-pressure curves/settings
The selection of the right proportional-pressure setting depends
on the characteristics of the system in question and the actual
flow rate demand.
7.1.1 Adjusting the proportional pressure using Grundfos GO
The set point of the proportional pressure curve can be adjusted
using Grundfos GO.
