11. Performance curves

11.1 Guide to performance curves

Each pump setting has its own performance curve. However,
AUTO covers a performance range.
ADAPT
A power curve, P1, belongs to each performance curve. The
power curve shows the pump power consumption in watt at a
given performance curve.

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 ρ = 983.2 kg/m
•
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
•
(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
with other densities, for example hot water, the outlet pressure
is proportional to the density.
• Curves are obtained according to EN 16297-2.
