2. Booster pump - Wikipedia

   en.wikipedia.org/wiki/Booster_pump

   The engine needs a fuel tank and an automatic controller that will start the booster pump when it is needed. A small auxiliary electrically-powered booster pump (called a "jockey pump") is often included in the system to maintain the sprinkler pipes at sufficient pressure, without requiring startup of the large diesel engine.

3. Diving air compressor - Wikipedia

   en.wikipedia.org/wiki/Diving_air_compressor

   Most high pressure diving air compressors are oil-lubricated multi-stage piston compressors with inter-stage cooling and condensation traps. Low pressure compressors may be single or two-stage, and may use other mechanisms besides reciprocating pistons. When the inlet pressure is above ambient pressure the machine is known as a gas booster pump.

4. Gas blending for scuba diving - Wikipedia

   en.wikipedia.org/wiki/Gas_blending_for_scuba_diving

   At this pressure and normal temperatures, air departs from linearity by about 5%, e.g. a 10-litre cylinder filled to 230 bar with air only contains about 95% of the expected 2300 litres of free air. Above this pressure, the composition of the final mix is difficult to predict using simple equations but needs the more complex Van der Waals equation.

5. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   The pressure switch turns the water pump on when it senses a pressure that is less than P lo and turns it off when it senses a pressure greater than P hi. While the pump is on, the pressure tank fills up. The pressure tank is then depleted as it supplies water in the specified pressure range to prevent "short-cycling", in which the pump tries ...

6. 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 ...
