A jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or ...

To the right of the turret was a selection lever, which would allow the turret to output foam or water depending on the turret operator's selection. A diagram of the MB-5's front hose reel. The handline was designed by Ardmore Mfg Co and was fed by a 150 pounds per square inch (1,000 kPa) centrifugal pump (built by Waterous Pump Co). [3]
rigid interlocking end-pieces on fire hose; used for connecting hose to hydrants or fire engine pumps and other hose appliances (nozzles, wyes, manifolds, strainers, etc.); standardized sizes and threads or other (non-threaded) pressure-sustaining interlocks (e.g., "Storz" or other "quarter-turn" connectors); lugs, cams, or pins are used to ...

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.
Self-priming pumps have to be capable of evacuating air from the pump suction line without any external auxiliary devices. Centrifugal pumps with an internal suction stage such as water-jet pumps or side-channel pumps are also classified as self-priming pumps. [10] Self-Priming centrifugal pumps were invented in 1935.
The air compressor also provides energy, which, gallon for gallon, propels compressed air foam rather than aspirated or standard water nozzles. It is proven that CAFS attacks all three sides of the fire triangle simultaneously. The foam blankets the fuel, thereby reducing the fuel’s capacity to seek a source of oxygen.
