2. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   VLOM, meaning Village Level Operation and Maintenance, is a term first used during the UNDP and World Bank Rural Water Supply Hand Pumps Project. This project lasted from 1981 to 1991, and studied the availability and maintenance of hand pump systems. 40 kinds of hand pumps were analyzed in laboratories, and the performance of 2700 hand pumps ...

3. Water pumping - Wikipedia

   en.wikipedia.org/wiki/Water_pumping

   The coil pump, if fitted with a suitable rotating seal, can deliver water to a greater height, typically 5-10m, above their discharge opening. [2] Despite the emergence of new pumps that operate on other principles, the coil pump remains an important tool as some of it other benefits are that they can be built and repaired easily at a very low ...

4. Hydraulic ram - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_ram

   The momentum of the water flow in the inlet pipe against the now closed waste valve causes a water hammer that raises the pressure in the pump beyond the pressure caused by the water column pressing down from the outlet. This pressure differential now opens the delivery valve [5], and forces some water to flow into the delivery pipe [3].

5. Condensate pump - Wikipedia

   en.wikipedia.org/wiki/Condensate_pump

   Small pumps have tanks that range from 2 to 4 liters (0.5 to 1 gallon) and are usually supported using the flanges on their tanks or simply placed upon the floor. A plastic impeller in a molded volute at the bottom of the pump provides the pumping action; this impeller is connected to the motor via a metal shaft that extends downwards from the ...

6. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   The device uses the water hammer effect to develop pressure that lifts a portion of the input water that powers the pump to a point higher than where the water 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 higher in elevation than ...

7. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   A diaphragm type pressurizer on a domestic rainwater system, with the pump and Square D pressure switch in the background. A pressure tank or pressurizer is a type of hydraulic accumulator used in a piping system to maintain a desired pressure. Applications include buffering water pressure in homes. [1]
