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 ...
Two models were listed, the smaller 120/220GPM model claimed 140 imperial gallons per minute (640 L/min) at 100 psi (690 kPa) with a ten-foot (three-metre) lift, the larger model was the 500GPM claiming 520 imp gal/min (2,400 L/min) at 100 psi (690 kPa) with a 10 ft (3 m) lift.
High volume pumps are also part of the New Dimension scheme. They carry a submersible pump, supplying water from any open source to the fireground; a pump that pumps up to 8,000 litres (1,800 imp gal) per minute (twice as much as a standard fire engine); a hose box module; and ancillary equipment.
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. One of the first companies to market a self-priming centrifugal pump was American Marsh in 1938. [citation needed] Centrifugal pumps that are not ...
A quintuple combination pumper or quint is a fire-fighting apparatus that serves the dual purpose of an engine and a ladder truck. “Quintuple” refers to the five functions that a quint provides: pump, water tank, fire hose, aerial device, and ground ladders. [1] Tillers and tractor-drawn aerials also have quint features, and are dubbed ...
The fire pump was reinvented in Europe during the 16th century, reportedly used in Augsburg in 1518 and Nuremberg in 1657. A book of 1655 inventions mentions a steam engine (called a fire engine) pump used to "raise a column of water 40 feet [12.2 m]", but there was no mention of whether it was portable.
The first fire extinguisher patent was issued to Alanson Crane of Virginia on Feb. 10, 1863. [12] The first fire sprinkler system was patented by H.W. Pratt in 1872. But the first practical automatic sprinkler system was invented in 1874 by Henry S. Parmalee of New Haven, CT. He installed the system in a piano factory he owned.
