Selection information Selection example Requirements: Specified duty point at: Flow rate: 4 m³/h Head: 5 m Solution: 1. Subtract the inlet pressure of 1 bar (approx. 1 m) from the head. ð This results in a required head of 4 m. 2. Transfer the values to the selection chart to select the corresponding pump. ð Here, it is a KSB Delta Compact 1 / 44-DE.
