2. Humphrey pump - Wikipedia

   en.wikipedia.org/wiki/Humphrey_Pump

   Water enters the pump through sprung inlet valves below the combustion chamber. A distinctive feature of the Humphrey pump, compared to others, is that the water only has to flow through this single set of valves: there are no non-return outlet valves, only the inertia of the delivered water within the outlet pipe is used to control its flow.

3. Metering pump - Wikipedia

   en.wikipedia.org/wiki/Metering_pump

   [2] Although metering pumps can pump water, they are often used to pump chemicals, solutions, or other liquids. Many metering pumps are rated to be able to pump into a high discharge pressure. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of discharge (outlet) pressure.

4. 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 ...

5. 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].

6. Lake bifurcation - Wikipedia

   Meanwhile, part of the lake's water naturally flows south through the Everglades into the Florida Bay. As a result of this artificial trifurcation, the Eastern Continental Divide of North America terminates at the lake rather than further south near Miami.

7. Gatehouse (waterworks) - Wikipedia

   en.wikipedia.org/wiki/Gatehouse_(waterworks)

   The Kinzua Dam in Pennsylvania, with outlet works releasing water. A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very ...
