9. Guide to performance curves
Each pump setting has its own performance curve
(Q/H curve). A power curve (P1 curve) belongs to each
Q/H curve. The power curve shows the pump power
consumption (P1) in Watt at a given Q/H curve.
The P1 value corresponds to the value that can be
read from the pump display. See fig. 14.
