11. Performance curves
11.1 Guide to performance curves
Each pump has its own performance curve.
A power curve, P1, belongs to each performance curve. The
power curve shows the pump power consumption in watt at a
given performance.
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
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 EEI values obtained according to EN 16297 part 3.
