The factory setting does not correspond to the output required for the system. The re-
quired pump capacity is determined with the help of the pump curve diagram for the
selected pump type (e.g. from the data sheet).
NOTICE
For water applications, the flow rate value shown in the display or output to the
building management system applies. For other fluids, this value only reflects the
tendency. If no differential pressure sensor is installed (variant ... R1), the pump can-
not indicate a volume flow value.
CAUTION
Risk of material damage!
An inadequate volume flow can lead to damage on the mechanical seal; the min-
imum volume flow depends on the speed of the pump.
• Make sure that the volume flow does not fall below the minimum value Q
min
.
Approximate calculation of Q
min
:
Q
min
= 10 % x Q
max pump
x actual speed / max. speed
