2. Diaphragm pump - Wikipedia

   en.wikipedia.org/wiki/Diaphragm_pump

   The basic working principle of an air-operated double diaphragm pump. Cross-section sketch of diaphragm fuel pump Air-operated double diaphragm pump. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve ...

   The air passes through a filter and the air hose to the diver's demand valve. Small 12 volt diaphragm compressors are used for recreational hookah, with a delivery of around 1.8 bars (26 psi), which severely limits the depth to which air can be supplied. The rubber diaphragm pump usually requires no oil lubricant and delivers oil-free air. [30]

4. Diaphragm (mechanical device) - Wikipedia

   A diaphragm pressure tank is a tank which has pressurant sealed inside on one side of the diaphragm. It is favored in certain applications due to its high durability and reliability. This comes with a downside, as the vessel needs to be replaced in the case of a rupture of the diaphragm. [2]

   The total pressure may have gravitational, static pressure and kinetic energy components; i.e. energy is distributed between change in the fluid's gravitational potential energy (going up or down hill), change in velocity, or change in static pressure. η is the pump efficiency, and may be given by the manufacturer's information, such as in the ...

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 ...

7. High-density solids pump - Wikipedia

   en.wikipedia.org/wiki/High-density_solids_pump

   Seat valve pumps are suitable for an especially even pumping of media with a solids content of up to 50% and for the high-pressure pumping of paste-like industrial media such as sludges. Since valves are used in this two-cylinder pump. it is limited to grain sizes of 8 mm at most.
