Density
The density is an important fluid property that depends on the temperature. The density of the pumped medium has a direct influence on the power requirement of the pump.
The mechanical power requirement of a centrifugal pump (shaft power) is directly proportional to the density of the pumped medium.
P 2 ~ ρ
P 2 = shaft power
ρ = density of the pumped medium
In contrast, the throttle curve of the pump H (Q) and the efficiency η (Q) are independent of the density.
These relationships are automatically taken into account by the pump selection software.
