Optimale Entscheidungen in OrganisationenBearings support the rotating elements of the pump and keep them in proper position relative to other parts and the driver. Failure of a bearing may change the position of the rotating elements, which will cause interference between the stationary and moving parts of the pump, and may lead to fractures or seizing of parts.

Rotodynamic PumpsThe term . refers to a class of devices that use rotating blades to increase the head of the pumped liquid, by altering its state of motion. This class of pumps includes the following: Axial flow, Centrifugal and mixed-flow, Regenerative pumps.

RecirculationFor many years, recirculation was regarded as some sort of mysterious factor responsible for every problem that could not be explained. As such, it had no exact definition suitable for analytical discussion. This sometimes led to inaccurate or misleading conclusions, as shown by the case history presented here.

Pumping System LayoutThe size and geometry of a sump, tank, or container from which liquid enters the suction line has enormous effects on pump performance. In particular, the choice of these parameters may be critical when the dimensions of the source where the pump gets its liquid is compared to the handled flow rate.
