2. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Centrifugal pumps with an internal suction stage such as water-jet pumps or side-channel pumps are also classified as self-priming pumps. [10] Self-Priming centrifugal pumps were invented in 1935. One of the first companies to market a self-priming centrifugal pump was American Marsh in 1938. [citation needed]

3. Centrifugal pump selection and characteristics - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump_selection...

   While centrifugal pumps impart momentum to the fluid by motion of blades, positive displacement pumps transfer fluid by variation in the size of the pump’s chamber. Centrifugal pumps can be of rotor or propeller types, whereas positive displacement pumps may be gear-based, piston-based, diaphragm-based, etc. As a general rule, centrifugal ...

5. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

6. Net positive suction head - Wikipedia

   en.wikipedia.org/wiki/Net_positive_suction_head

   The Required NPSH (NPSH R): the head value at the suction side (e.g. the inlet of a pump) required to keep the fluid away from cavitating (provided by the manufacturer). NPSH is particularly relevant inside centrifugal pumps and turbines , which are parts of a hydraulic system that are most vulnerable to cavitation.
