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 ...
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.
He took out two patents for fire engines in 1721 and 1725 (Royal Patent Office 1721 patent #439 and 1725 patent #479) and soon dominated the fire engine market in England. [1] The engine had two single-acting pistons and an air vessel placed in a tank which formed the frame of the machine. The pump was worked by people at the long cross handles.
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.
Variable Speed Fire Pump Controllers were invented and released with a UL Listing for fire pump service in 2003 by Master Control Systems, Inc. [1] [2] Paragraph 10.5.5 in the 2003 edition of NFPA-20 recognized Variable Speed as an accepted method for operating the fire pump. Then in the NFPA-20 2007 edition, section 10.10 was added to clarify ...

By 1938 large numbers of the Coventry trailer pumps were being purchased by fire brigades, and demonstrated to ARP staff and members of the Auxiliary Fire Service. The "Coventry Climax trailer pump" was described as being capable of delivering 250–300 imperial gallons per minute (1,100–1,400 L/min).
Where it is necessary to raise water to a height above that to which a suction or lift pump will operate effectively (about 7 metres), or to raise the pressure so that it will exit a nozzle with a strong force, such as through a fire hose, a force pump may be used. As with a suction pump, in its manual form it relies on an operator to pump a ...
