differential head?
Thread Content
It is the reference in the centrifugal pump data sheet. The unit is 75 m. I wonder if it means "differential pressure head"?
Kingsoft PowerWord has it: Unequal pressure head
You can find a book related to centrifugal pumps. Differential head literally means head difference, which refers to the difference between the total head at the outlet of the centrifugal pump and the total head at the inlet. It can be considered as the theoretical head measured by the centrifugal pump test. For example, install a pressure gauge at the import and export.

It should mean the pressure head, which is equivalent to the lift. This post was last edited by beileim1 on 2009-2-19 12:41 ]
Just translate it directly into "differential pressure head".
