Any Fire Fighting Pump station should always have Three important pumps :
1. One Electrical pump (Which is the main or Duty pump)
2. One Diesel Pump (Which is the Standby pump)
3. Jockey pump.
Types of Fire Fighting Pumps
The different types of fire fighting pumps are water jet, jet chain, blower, water and oil, fire pump and so on.
The water and oil type of pump is manufactured in various sizes and capacities. Most of the water and oil fire fighting pumps are manufactured in 300 and 500 gallons capacities, however the fire pumps in larger capacities such as 1000 gallons capacity are manufactured mostly in China.
The demand for the fire fighting pumps has been driven by the development of the construction industry and the increase in the number of fires caused by various reasons such as homeless fires and cooking fires.
Some of the notable market players in the fire fighting pumps market include- Xylem Inc., Legrand SA, ABB Ltd., RMR Group Inc., Pentair plc, General Electric, Siemens AG, Honeywell International Inc., Thomas & Betts Corporation, and DOXA Fire & Safety.
Inline Fire Fighting Pumps
Inline fire fighting pumps are designated Type (P), Type (B), Type (C), Type (E), Type (F), Type (G), Type (H) or Type (I) depending on the hose width or pneumatic pressure rating (HP) of their pump.
They are fitted with a trigger control for fighting fires in conjunction with a fire fighting hydrant.
The earliest types of fire pump were hand operated.
The first modern electrical fire pump was invented in 1899 by Elmer E. Grover, professor of hydraulics at the University of Wisconsin–Madison.
It used high pressure vacuum pipes for water supply, a hand pump for operating the pump, and a manual feed from the hydrant.
This pump used an electrical generator and transformer.
In 1920, the first electrically operated manual pump was developed by Elmer Grover and Alfred A. Cleary.
In 1926, the Phillips Company, based in North Tonawanda, New York, introduced a pneumatic fire pump that was driven by a motor.
The first electrically operated manual pump with an integral water supply system was also developed at the Phillips plant in 1927.
By the early 1930s, the number of companies manufacturing fire pumps had grown considerably.
During World War II, the demand for fire fighting pumps exceeded the capacity of the Phillips plant, and the company was contracted to manufacture the pumps for the United States Navy.
At that time, the pumps were installed in fire stations around the nation.
The War Production Board recommended that manufacturers only produce the necessary number of pumps to meet demands.
This resulted in numerous manufacturers lowering their prices to the war effort.
The smaller pump manufacturers, such as the Phillips Company, grew very quickly, but these companies began to experience significant problems.
One of the major problems with many of the smaller companies was the cost of equipment.
End Suction pumps
End Suction Fire fighting pumps operating at 30Hz, 100Hz and 1,000Hz to increase the pump horsepower and to reduce the frequency of back-to-back operations. An end suction fire pump is similar in operation to a single speed pump in that it is powered by a motor and is directed to operate on the 1,000 Hz mode. The 1,000 Hz mode produces much more pressure than a conventional 100 Hz pump and works much more effectively at high volumes. In terms of efficiency, end suction fires are slightly more expensive to run than the 50 Hz pumps with the difference narrowing the further up the efficiency scale you go. Suction fires are often used for narrow or closely spaced channels, thus they are not ideal for use in a pipeline and require the contractor to add a limiter to them.
Exhaust Liquid Pressure is Directed to the Fire for Efficiently Combustion
End suction fire pumps use a special nozzle that releases air from a tube within the pump which leads directly to the fire. This method of delivering water through the fire significantly reduces the water consumption and therefore the pressure that is applied to the fire, while reducing its fuel consumption, thereby increasing the efficiency and effectiveness of the water feeding the fire. Exhaust Liquid Pressure (ELP) is measured in Litres per Second (LPS), and is delivered at a flow rate of 1,500 LPS per pump per second. Each pump has two outlets which have to be connected by an outlet valve to the fuel supply line. The other two outlets can be used for the return of the water, or to link a number of pumps together in an array. A full service centre usually has a number of existing outlets for each pump and this is done by simply removing the outlet valves from the tanks to make each individual pump available as an outlet valve.
Vertical Turbine Fire Pumps
Vertical Turbine Fire Fighting Pumps are manufactured from high temperature copper alloys and are capable of operating in extreme environments and provide uninterrupted power even in continuous supply at normal flow conditions. These fire pumps are fitted with diamond like inclusions to enhance their hydraulic characteristics. These pumps ensure minimal friction and provide excellent absorption of heat. These fire pumps are suitable for application in various industries such as chemical, construction, petrochemical, pharmaceutical, oil & gas, paper and pulp, and other application segments.
Vertical Turbine Fire Fighting Pumps Market: Dynamics
The increasing adoption of these pumps in various end-user industries is projected to fuel the growth of the global vertical turbine fire fighting pumps market over the forecast period. The rising adoption of these pumps is due to their ability to function under extreme conditions and the ability to operate continuously in a continuous supply mode. The increasing adoption of these pumps is one of the primary factors projected to boost the growth of the global vertical turbine fire fighting pumps market during the forecast period.
Vertical inline pumps
Vertical Inline fire fighting pumps are based on the axial flow principle.
They are a specialised fire pump with the specific aim of protecting adjacent buildings from the spread of a fire.
They work best in enclosed buildings, with confined spaces and/or very high pressure water supplies.
Some models are designed for multiple user and centralised control (user operated), others work as pumps alone.
These are particularly useful in areas which are prone to industrial fires, as they pump in a single direction and can work on a continuous fire, yet at very high pressure (600 bars at .
The fire fighting piston is the point that sits directly on the fire, and this allows very high pressure water to be continuously pumped.
The fire pump consists of a cylinder of copper alloy, the water tank and a piston.
Horizontal Split case fire pumps
A Horizontal Split case pump is a special sort of outward centrifugal pump whose casing is separated into two different chambers, which is not quite the same as inline or end Suction type of Fire Pumps that are collected with the suction nozzle, discharge nozzle, and casing, all in one chamber.
Contingent upon your particular application, you can decide on either the single stage Horizontal Split Case pump with a head of up to 550 feet at 140,000 gallons per minute, or the multi-stage Horizontal Split Case pump with a most extreme head of 2.200 ft, worst case scenario. working pressure of 740 psi, and stream scope of up to 2,000 gallons per minute, which is appropriate for hard core, high pressure applications.
