CENTRIFUGAL PUMP

A centrifugal pump has at least one impeller, a pump housing and an electrical motor. The pump has a Q-H pump curve having a head H0 at zero flow and a head Href corresponding to the highest hydraulic power, and that Href is greater than H0. The pump has low energy consumption rate, especially at lo...

Beschreibung
Zusammenfassung:	A centrifugal pump has at least one impeller, a pump housing and an electrical motor. The pump has a Q-H pump curve having a head H0 at zero flow and a head Href corresponding to the highest hydraulic power, and that Href is greater than H0. The pump has low energy consumption rate, especially at low flow corresponding to the conditions in which the pump is operated most of the time. Thus, the pump according to the invention is less energy consuming than the prior art centrifugal pumps.
