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 ...
A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...
Fire hydrant in Charlottesville, Virginia, United States. 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 ...
Fire hose. Indoor fire hose with a fire extinguisher. A fire hose (or firehose) is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine, fire hydrant, or a portable fire pump. [1] Indoors, it can permanently attach to a building's standpipe or ...
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.
Firefighter from Warsaw wearing equipment for breathing in smoke ca. 1870. The history of organized firefighting began in ancient Rome while under the rule of the first Roman Emperor Augustus. [1] Prior to that, Ctesibius, a Greek citizen of Alexandria, developed the first fire pump in the third century BC, which was later improved upon in a ...

A Variable Speed (VFD) Fire Pump Controller is a fire pump controller that is able to vary the speed of the motor depending on the demand of the fire pump, resulting in the ability to hold a constant discharge pressure. It differs from other industrial variable speed control devices because it is now considered a life safety device, and so must ...
