Centrifugal Pumps - Marine Engineering Study Materials

29/04/2014  Centrifugal. Flow through the pump is induced by the centrifugal force imparted to the liquid by the rotation of an impeller or impellers.Centrifugal pumps are not self-priming pumps. These pumps must be primed by gravity or by priming equipment external or internal with the pump.These pumps are basically radial flow, axial flow or mixed flow type.

Pump Sizing - The Effects of Oversizing Centrifugal

15/07/2019  Control valves installed in system featuring centrifugal pumps tend to stay in restrictive valve positions which in turn forces the pump to work against a high back pressure. Since this is higher than the pressure required for the pump to achieve its best efficiency point (see previous blog-post titled “Operating Efficiency of Centrifugal Pumps”), the pump runs inefficiently and at risk of ...
