6 Selection information Minimum pressure The minimum pressure p min at the pump suction nozzle serves to avoid cavitation noises at an ambient temperature of +40 C and the indicated fluid temperature T max. 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.
