2. 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 ...

3. Rotodynamic pump - Wikipedia

   en.wikipedia.org/wiki/Rotodynamic_pump

   A rotodynamic pump is a kinetic machine in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor, in contrast to a positive-displacement pump in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge. [1]

4. Slurry pump - Wikipedia

   en.wikipedia.org/wiki/Slurry_pump

   A self-priming slurry pump is operated from land, and a hose is connected to the pump's intake valve. The self-priming pump draws the slurry to the pump then discharges the material from there. Flooded Suction The flooded suction slurry pump is connected to a tank or hopper and uses gravity to move slurry and liquid from the enclosure.

5. 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 ...

6. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [ 5 ]
