Selection information
Minimum pressure
The minimum pressure pmin at the pump suction nozzle serves
to avoid cavitation noises at an ambient temperature of +40 °C
and the indicated fluid temperature Tmax.
The indicated values are applicable up to 300 m above sea
level. For installation at altitudes > 300 m, an allowance of
0.01 bar / 100 m must be added.
Minimum pressure pmin [bar] specified for the fluid temperature [°C]
