2. Booster pump - Wikipedia

   en.wikipedia.org/wiki/Booster_pump

   Haskell booster set up for charging rebreather cylinders from premix banks with low pressure compressor. A booster pump is a machine which increases the pressure of a fluid. It may be used with liquids or gases, and the construction details vary depending on the fluid. A gas booster is similar to a gas compressor, but generally a simpler ...

3. Fire pump - Wikipedia

   en.wikipedia.org/wiki/Fire_pump

   Fire pumps are used to increase the pressure of water sourced from a municipal underground water supply piping network, or a static supply (e.g., tank, reservoir, lake). A fire pump is a centrifugal- or positive displacement- pump that has been tested and listed by a third-party testing and listing agency, such as UL or FM Global specifically ...

4. Rotary vane pump - Wikipedia

   en.wikipedia.org/wiki/Rotary_vane_pump

   4. spring. A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases, these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. This type of pump is considered less suitable than other vacuum pumps for ...

5. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Warman centrifugal pump in a coal preparation plant application. A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...

6. Fire hydrant - Wikipedia

   en.wikipedia.org/wiki/Fire_hydrant

   Fire hydrant. A fire hydrant, fireplug, firecock (archaic), [1] hydrant riser or Johnny Pump[2] is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. Underground fire hydrants have been used in Europe and Asia since at least the 18th century.

7. Hydraulic ram - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_ram

   A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to ...
