11. Performance curves
11.1 Guide to performance curves
Each pump setting has its own performance curve. However,
AUTO
ADAPT
covers a performance range.
A power curve, P1, belongs to each performance curve. The
power curve shows the pump power consumption in watt at a
given performance curve.
The P1 value corresponds to the value that you can read from the
pump display. See fig. 35.

7. Control functions
11.2 Curve conditions
The guidelines below apply to the performance curves on the
following pages:
• Test liquid: airless water.
• The curves apply to a density of 83.2 kg/m
3
and a liquid
temperature of 60 °C.
• All curves show average values and must not be used as
guarantee curves. If a specific minimum performance is
required, individual measurements must be made.
• The curves for speeds I, II and III are marked.
• The curves apply to a kinematic viscosity of 0.474 mm
2
/s
(0.474 cSt).
• The conversion between head H [m] and pressure p [kPa] has
been made for water with a density of 1000 kg/m
3
. For liquids
with other densities, for example hot water, the outlet pressure
is proportional to the density.
• Curves obtained according to EN 16297.
