Fire Pump

A fire pump is a reliable water pressure boosting device designed for fire protection systems, increasing water flow and pressure to ensure sufficient water supply for sprinklers, fire hydrants, and other firefighting equipment. Used when the existing water supply cannot meet required fire protection demands, fire pumps are widely applied in commercial buildings, industrial facilities, high-rise buildings, and municipal fire water supply systems.

How Does a Fire Pump Work?

A fire pump works by using an electric motor or other power source to drive the impeller inside the pump. As the impeller rotates, it converts mechanical energy into hydraulic energy, increasing the pressure and flow of incoming water. The pressurized water is then delivered through the fire protection pipeline to equipment such as sprinklers, fire hydrants, and standpipe systems. Fire pumps provide reliable pressurized water supply for emergency firefighting applications when additional flow and pressure are required.

Common Types of Fire Pumps

Among these fire pump types, ATO offers vertical single stage fire pumps designed for clean water fire protection applications. The available models cover power ratings from 2 HP to 50 HP, with flow capacities from 6.5 m³/h to 70 m³/h and head ranges from 32 m to 128 m. Featuring a vertical inline structure, ATO fire pumps are suitable for applications requiring reliable pressurized clean water supply in residential, commercial and industrial fire protection systems.

• Vertical Single Stage Fire Pump: Uses one impeller to increase water pressure and provide stable flow for fire protection systems. It is commonly selected for applications requiring moderate pressure performance, compact installation and reliable water supply.
• Vertical Multistage Fire Pump: Uses multiple impellers arranged in series to generate higher pressure output. It is suitable for applications requiring greater head performance, such as high-rise buildings, long pipeline systems and projects with higher hydraulic resistance.
• Electric Motor Driven Fire Pump: Uses an electric motor as the driving source and is widely used in fixed fire protection systems where a stable electrical supply is available.
• Diesel Engine Driven Fire Pump: Used in applications where independent operation or backup power capability is required, especially when electrical power availability is limited.

Fire Pump Applications and Selection Guide

• Residential and Commercial Fire Protection: Fire pumps are widely used in apartment buildings, residential complexes, hotels, shopping centers and office buildings to provide sufficient water pressure and flow for sprinkler systems and fire hydrant networks. For these applications, pump selection mainly depends on building height, fire protection layout and required water demand.
• Industrial Fire Protection Systems: Factories, warehouses, manufacturing plants and industrial facilities often require fire pumps to support large-scale sprinkler systems and fire water networks. Selection should consider the required flow rate, pressure level, pipeline length and operating conditions.
• High-Rise Buildings: High-rise buildings usually require higher pressure performance due to elevation differences between the pump location and upper floors. Fire pump selection should include accurate calculation of static head, pipeline friction loss and required outlet pressure.
• Infrastructure Applications: Large facilities, utility projects and municipal fire protection systems use fire pumps where reliable emergency water supply is required. The selected pump should match the overall system capacity and operational requirements.
• Key Selection Factors: When selecting a fire pump, consider the required flow rate, pressure head, power source, installation space and system design requirements. The correct pump type should be determined through hydraulic calculation rather than by flow capacity alone.

FAQ

Q: When is a fire pump required?
A: A fire pump is required when the available water supply cannot provide the pressure or flow required by the fire protection system. It is commonly used in buildings where elevation, pipeline distance or system demand affects available water pressure.
Q: Can a fire pump run automatically during a fire emergency?
A: Yes. Fire pumps can be integrated with automatic fire protection control systems to start when the system detects a pressure drop or firefighting water demand.
Q: What is the difference between a standby fire pump and a duty fire pump?
A: A duty fire pump is the primary pump responsible for supplying water during firefighting operation, while a standby fire pump provides backup support to improve system reliability when the primary pump is unavailable.
