Characteristic curves
General
Test class: Characteristic curves to ISO 9906 Class 3B
NPSH values
The NPSH values indicated in the characteristic curves
correspond to a head drop of 3 %.
NPSH values in low-flow conditions
NPSH values for flow rates below Q = 0.3 x Q
opt
can only be
measured with intense technical efforts. Evidence of NPSH
values in the low-flow range cannot be provided.
Density of the fluid handled
The indicated heads and performance data apply to pumped
fluids with a density ρ = 1.0 kg/dm
3
and a kinematic viscosity v
of up to 20 mm
2
/s max. If the density ≠ 1.0, the performance
data must be multiplied by ρ. For viscosities >20 mm
2
/s the
corresponding data for cold water has to be calculated and the
impact on the pump's performance has to be determined.
Correction factors
The characteristic curves apply to pumps with cast iron or
bronze impellers. When using an impeller made of cast steel
materials the efficiency and pump power of the corresponding
pump sizes have to be multiplied by the correction factors
indicated in the characteristic curves.
