2. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   Hand-powered force pump, with an air chamber to smooth out variations in flow rate. Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities.

3. Stirrup pump - Wikipedia

   en.wikipedia.org/wiki/Stirrup_pump

   A stirrup pump is a portable reciprocating water pump used to extinguish or control small fires. [1] It is operated by hand. The operator places a foot on a stirrup-like bracket at the bottom of the pump to hold the pump steady, the bottom of the suction cylinder is placed inside a bucket of water. [2]

4. Treadle pump - Wikipedia

   en.wikipedia.org/wiki/Treadle_Pump

   A treadle pump is a human-powered suction pump that sits on top of a well and is used for irrigation. [1] It is designed to lift water from a depth of seven metres or less. The pumping is activated by stepping up and down on a treadle, which are levers, which drive pistons, creating cylinder suction that draws groundwater to the surfa

5. Reciprocating pump - Wikipedia

   en.wikipedia.org/wiki/Reciprocating_pump

   Simple hand-operated reciprocating pump. The simplest example is the bicycle pump, which is used ubiquitously to inflate bicycle tires and various types of sporting balls. [1] Power-operated deep well reciprocating pump; By mechanism. Single-acting reciprocating pump consists of a piston of which only one side engages the fluid being displaced. [2]

6. Pump - Wikipedia

   A minimum flow protection system ensures that the pump is not operated below the minimum flow rate. The system protects the pump even if it is shut-in or dead-headed, that is, if the discharge line is completely closed. [44] The simplest minimum flow system is a pipe running from the pump discharge line back to the suction line.

7. Airlift (dredging device) - Wikipedia
