How is the total delivery head defined?

The dynamic total delivery head is also referred to as the "delivery head" or simply as the "total delivery head". In the technical literature, the total delivery head is defined as the work that needs to be performed by the pump to pump the medium with reference to a defined unit of weight. Expressed more simply, the delivery head is equal to the pressure measured at the discharge port minus the inlet pressure applied at the suction port. The delivery head is generally specified in m. Generally speaking, the delivery head is represented together with the flow rate in the form of the QH curve.
