2. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   Uses of pneumatic pressure switches include: Switch a household well water pump automatically when water is drawn from the pressure tank. Switching off an electrically driven gas compressor when a set pressure is achieved in the reservoir; Switching off a gas compressor, whenever there is no feed in the suction stage. in-cell charge control in ...

3. Water pumping - Wikipedia

   en.wikipedia.org/wiki/Water_pumping

   Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in Asia. [1] The coil pump was built as an alternative to the Archimedean screw. Unlike the Archimedean screw ...

4. Hydraulic ram - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_ram

   The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination ...

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. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   A chain pump is a type of water pump that uses a chain to move water from one place to another. It works on the principle of a continuous loop of chain moving through a series of sprockets, with attached buckets that lift water as the chain passes over the top sprocket and discharge it as the chain reaches the bottom.

7. Sump pump - Wikipedia

   en.wikipedia.org/wiki/Sump_pump

   Automatic vs. manual operation – pump may be controlled automatically by a level switch. Power – Sump pump motive power will vary from 1/4 horsepower to multiple horsepower. Head pressure – The hydraulic head pressure of a sump pump describes the maximum height to which the pump will move water. For instance, a sump pump with a 15 feet (4 ...
