Defined as the effective mechanical force exerted by the pump onto the pumped fluid and expressed as unit of weight at the local gravitational constant.
It is, at constant speed and constant flow, independent of the density of the fluid, but dependent on its viscosity.
The static head means that part of the system H-Q curve that is unrelated to the flow.

Decisive for the design is the expected wastewater discharge.

The pumping performance of a centrifugal pump is expressed in the form of an H-Q curve, depicting the Flow Q (e.g. in m³/h) and the Head H (e.g. in m) of the pump.

The system H-Q curve depicts the dependency of the total head Hsystem on the Flow Q.

The system H-Q curve is essentially a parabolic curve representing the relation between the head (pressure) required to handle the respective rate of flow within a pipe system.
