2. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   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] Centrifugal pumps that are not designed with an internal or external self-priming stage can only start to pump the fluid after the pump has initially been primed with the fluid.

3. Slurry pump - Wikipedia

   en.wikipedia.org/wiki/Slurry_pump

   Centrifugal, positive displacement, and vortex pumps can be used for slurry. Centrifugal slurry pumps can have between bearing-supported shafts with split casing or rubber- or metal-lined casing. Configurations include horizontal, vertical suspended and submersible. Slurry is usually classified according to the concentration of solids ...

4. 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. Fire pump - Wikipedia

   en.wikipedia.org/wiki/Fire_pump

   A fire pump is a centrifugal-or positive displacement-pump that has been tested and listed by a third-party testing and listing agency, such as UL or FM Global specifically for fire service use. The main standard that governs fire pump fixed-place installations in North America is the National Fire Protection Association 's NFPA 20 Standard for ...

6. Rotodynamic pump - Wikipedia

   en.wikipedia.org/wiki/Rotodynamic_pump

   By type of case split: Axial split: In these types of pumps the volute casing is split axially and the split line at which the pump casing separates is at the shaft's centerline. They are typically mounted horizontally due to ease in installation and maintenance. Radial split: The pump case is split radially, the volute casing split is ...

7. Volute (pump) - Wikipedia

   en.wikipedia.org/wiki/Volute_(pump)

   Pump and volute casing. A volute is a curved funnel that increases in area as it approaches the discharge port. [1] The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the ...
