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]

5. 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.

6. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   These pumps are basically multistage centrifugal pumps and are widely used in oil well applications as a method for artificial lift. These pumps are usually specified when the pumped fluid is mainly liquid. Buffer tank A buffer tank is often installed upstream of the pump suction nozzle in case of a slug flow. The buffer tank breaks the energy ...

7. Circulator pump - Wikipedia

   en.wikipedia.org/wiki/Circulator_pump

   Circulator pumps as used in hydronic systems are usually electrically powered centrifugal pumps. As used in homes, they are often small, sealed, and rated at a fraction of a horsepower , but in commercial applications they range in size up to many horsepower and the electric motor is usually separated from the pump body by some form of ...
