2. Hand pump - Wikipedia

   en.wikipedia.org/wiki/Hand_pump

   The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [5] The height to which a hand pump will lift is governed by the ability of the pump and the operator to lift the weight in the delivery pipe.

3. 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

4. Net positive suction head - Wikipedia

   en.wikipedia.org/wiki/Net_positive_suction_head

   If an NPSH A is say 10 bar then the pump you are using will deliver exactly 10 bar more over the entire operational curve of a pump than its listed operational curve. Example: A pump with a max. pressure head of 8 bar (80 metres) will actually run at 18 bar if the NPSH A is 10 bar. i.e.: 8 bar (pump curve) plus 10 bar NPSH A = 18 bar.

5. Suction (medicine) - Wikipedia

   en.wikipedia.org/wiki/Suction_(medicine)

   In surgery suction can be used to remove blood from the area being operated on to allow surgeons to view and work on the area. Suction may also be used to remove blood that has built up within the skull after an intracranial hemorrhage. [2] Suction devices may be mechanical hand pumps or battery or electrically operated mechanisms.

6. Airlift (dredging device) - Wikipedia

   en.wikipedia.org/wiki/Airlift_(dredging_device)

   It is a type of suction dredge. A water dredge or water eductor may be used for the same purpose. [1] Typically, the airlift is constructed from a 3-metre to 10 metre long, 10 cm diameter pipe. A controllable compressed air supply vents into the inside, lower end of the pipe (The input end always being the lower end).

7. Total dynamic head - Wikipedia

   en.wikipedia.org/wiki/Total_dynamic_head

   In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.

8. Hard suction hose - Wikipedia

   en.wikipedia.org/wiki/Hard_suction_hose

   5-inch (13 cm) flex suction hose with Storz fittings, mounted on an engine. Flexible suction hose (Flex suction or suction hose), not to be confused with hard suction hose in U.S., is a specific type of fire hose used in drafting operations, when a fire engine uses a vacuum to draw water from a portable water tank, pool, or other static water source.
