2. Water pumping - Wikipedia

   en.wikipedia.org/wiki/Water_pumping

   The Archimedean screw must be tilted at an angle. The spiral pump, if fitted with a suitable rotating seal, can deliver water to a greater height than the coil pump, typically 5-10m, above their discharge opening. Its main drawback is that the output is small - an output proportional to the volume of the largest coil being moved each revolution ...

3. 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 ...

4. Circulator pump - Wikipedia

   en.wikipedia.org/wiki/Circulator_pump

   This avoids one of the principal challenges faced by the larger, two-part pumps: maintaining a water-tight seal at the point where the pump drive shaft enters the pump body. Small- to medium-sized circulator pumps are usually supported entirely by the pipe flanges that join them to the rest of the hydronic plumbing. Large pumps are usually pad ...

   Built-in small storage water reservoir as part of heat exchanger (typically between 2 US gallons (7.6 L; 1.7 imp gal) to 20 gallons) Dual activation: flow sensing and thermostat control; Hybrid water heaters can be gas-fired (natural gas or propane), or be electrically powered using a combination of heat pump and conventional electric heating ...

6. Hydraulic ram - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_ram

   The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally 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 ...
