Best flow rate

The liquid to be pumped (pumped medium) has a fundamental influence on the selection and configuration of a pump.

Decisive for the design is the expected wastewater discharge.

The precipitation values are climatically conditioned and regionally very different. Depending on their frequency, the rainfall donations that occur are differentiated into:

The affinity law describes the speed dependency of the delivery parameters of centrifugal pumps. It can be derived from the general similarity relationships as a special case.

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 pump performance chart is a summarized diagram containing multiple pump performance curves.
