ABSTRACT:
A centrifugal pump with its impeller arranged beside the main media current in the pump housing (Vortex impeller pump) is provided with an inner part of resilient material which part forms the inlet of the pump. When a certain maximum volume goes into the pumphousing, the inlet edges fold inwards thus diminishing the inlet area and preventing the volume current from increasing over a certain value.
