A fire pump is an essential part of a fire protection system. A fire pump is a component of the water supply for a fire sprinkler system and it is powered by electricity or diesel. The public underground water supply piping or a static water source both are connected to the pump intake (e.g., tank, reservoir, lake). The pump delivers water to the sprinkler system risers and hose standpipes at a higher pressure. Electric motors, diesel engines, or occasionally steam turbines power fire pumps. When the pressure in the fire sprinkler system falls below a certain level, the fire pump turns on. When one or more fire sprinklers are exposed to heat above their design temperature, the sprinkler systems pressure significantly decreases, and the sprinklers open, releasing water. A pressure drop in the fire fighting main may also result from the opening of additional fire hose reels or other fire fighting connections.
Diesel fire pumps also referred to as booster pumps, are utilized to increase water pressure from sources that fall short of the requirements for sprinkler system operation. A fire pump may be connected to a tank, reservoir, or city water main used for fighting fires. The efficiency of the pump’s operation affects the fire protection system’s dependability. In some cases, a secondary source of water (like a tank or pond) may exist, and the pump is essential to the operation of that system. Where there may be an issue with the local electric grid’s dependability, diesel fire pumps are frequently used. For large, highly valued facilities, diesel fire pumps frequently serve as a secondary water pumping source to a primary electric pump.
In fire sprinkler systems, electric fire pumps, also referred to as “booster pumps,” raise the water pressure. If the water supply does not have enough pressure to operate a sprinkler system, think about using booster pumps. A city water main, water tank, reservoir, or pond that is aimed for use in fighting fires is connected to fire pumps. The efficiency of a fire protection system is dependent on the pump’s performance. Sometimes it’s necessary to have a backup water supply. Additionally, the system is typically powered by a fire pump with an electric motor.
Offshore production platforms like FPSOs and conventional ones use fire protection, which is typically provided by a firewater pump and a high-pressure firewater ring main.
Firewater pumps are typically vertical line-shaft, conventional pumps powered by a diesel engine through a 90° gearbox. However, this solution necessitates extensive upkeep. Sulzer Pumps offers several affordable improvements to this important application through its unique hydraulic drive fire pump design.
A fire pump is a crucial component of a fire sprinkler system because it gives the system access to high-pressure water and boosts water flow.
It’s necessary to understand what a fire pump is to understand how it functions. A fire pump is made up of the motor, also known as the driver, and the controller in addition to its namesake, the pump, which is an essential component of the system. A fire pump that is a component of a fire sprinkler system draws water from an underground water source, a water tank, a lake, or a reservoir, and is powered by either electricity or diesel fuel. Water is distributed through the sprinkler system and hose standpipes using the pump’s high pressure.
The horizontal split case, vertical split case, vertical in-line, and vertical turbine are typical fire pump designs.
Horizontal split case fire pump – The horizontal split case fire pump is the most popular model. For applications requiring higher flows, these pumps are the most cost-effective and are simple to service. They are even more well-liked due to their lengthy lifespans and size availability.
Vertical split case fire pumps – They require less space due to their vertical design, which also shields the pump from potential flooding damage; vertical split case fire pumps and horizontal split case fire pumps have many similarities.
Vertical in-line fire pump – The vertical in-line pump is a single-stage centrifugal pump intended for vertical installation, as the name suggests. This pump is perfect for small spaces because the suction and delivery ports are parallel to one another, ensuring a smooth flow of water throughout the system. For any repairs or maintenance, the pump must be removed due to the design.
Vertical turbine – A centrifugal pump called a vertical turbine was created for use in fire pump applications when the water source is underground. There are various variations of this fire pump, including water- and oil-lubricated open-line-shaft pumps. The installation of both types is intended for drilled wells, lakes, streams, open swamps, and other subsurface sources.
The installation and upkeep of any fire system should be handled by fire safety experts, just like the choice of pump and system. Numerous factors must be taken into account following the frequently updated International Building Code (IBC) and National Fire Protection Association (NFPA).
The monthly, annual, and subsequent inspections and maintenance should be carried out by qualified staff, including factory-trained and certified experts, professionals certified by a nationally recognized fire protection organization, or registered staff. Weekly inspections may be carried out by trained personnel on-site.
A fire pump is an essential fire and life-safety equipment in many buildings. Before installing any unit, there are a lot of conditions and factors to take into account. To guarantee a well-planned and legal final installation, the building owner, architect, engineer, local fire marshal, and fire protection provider should all take part in the discussion for the pump and system. Safety Line supplies certified fire pumps that comply with the highest international standards. Fire pumps are a crucial part of a fire sprinkler system and will form an important part of your building’s fire protection system.
