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. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   Deep well hand pumps are used for high lifts of more than 15 m. The weight of the column of water is too great to be lifted directly and some form of mechanical advantage system such as a lever or flywheel is used. High lift pumps need to be stronger and sturdier to cope with the extra stresses.

Note that modern pumps have an area contact between rotor and stator (and not a line contact). 1. pump housing 2. rotor 3. vanes 4. spring. A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In ...

   If rotary pumps are operated at high speeds, the fluids cause erosion, which eventually causes enlarged clearances that liquid can pass through, which reduces efficiency. Rotary positive-displacement pumps fall into five main types: Gear pumps – a simple type of rotary pump where the liquid is pushed around a pair of gears.

6. High-density solids pump - Wikipedia

   en.wikipedia.org/wiki/High-density_solids_pump

   The rotary circulation pumps includes eccentric screw pumps, centrifugal pumps, and squeezed tube (peristaltic) pumps. Reciprocating pumps include plunger, diaphragm, and piston pumps. The high-density solids pumps which can be used in the widest range of situations are piston (or reciprocating) pumps.

7. 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.
