General

NPSH valuesThe NPSH values indicated in the characteristic curvescorrespond to a head drop of 3 %.

NPSH values in low-flow conditionsNPSH values for flow rates below Q = 0.3 x Qopt can only bemeasured with intense technical efforts. Evidence of NPSHvalues in the low-flow range cannot be provided.

Density of the fluid handled The indicated heads and performance data apply to pumpedfluids with a density ρ = 1.0 kg/dm3 and a kinematic viscosity ofup to 20 mm2/s max. If the density ≠ 1.0, the performance datamust be multiplied by ρ. For viscosities >20 mm2/s thecorresponding data for cold water has to be calculated and theimpact on the pump's performance has to be determined.

Friction loss For some design variants (reinforced bearings, specific shaftseals) friction losses must be considered and indicated asadditional power requirement in the data sheet.
