A fire pump is required when the available pressure from the water system is insufficient to supply adequate pressure to all of the sprinkler heads in the structure at the required flow. The required flow is based on heads activating in a given area, which is determined by the hazard to be protected. Fire pumps are more commonly needed in taller buildings, but can also occur in shorter buildings in hilly locations.

Fire pump room design is vital for system functionality, accessibility, and safety. This article delves into the key considerations when designing a fire pump room, such as space requirements, ventilation, and fire suppression. It emphasizes the importance of a well-designed pump room to ensure optimal pump performance and personnel safety.

Stationary Pumps for Fire Protection: The diagram illustrates for a diesel-driven horizontal End suction fire pump assembly, electric fire pump as duty, a diesel drive pump as the backup.

Fire pumps are often required to have backup power sources, such as diesel generators or uninterruptible power supplies (UPS), to ensure they function during power outages.

Fire pumps have a wide range of uses. In addition to providing water for fire-fighting piping systems, they can also be used for industrial water delivery. Fire pumps can also be used for water supply and drainage systems in cities. There are other relatively long-distance water delivery tasks, such as heating boilers, hot and cold water circulation pressurization of bathroom boilers, etc., which can all be completed by means of fire pump systems.

Fire pumps used in different fields have different professional characteristics. For example, fire pumps in the general sense are installed on professional fire trucks or other special fire-fighting facilities, and are used to transport water and foam solutions for fire-fighting Pump.

A fire pump is designed to provide adequate water pressure to a sprinkler system during a fire emergency. It is usually powered by an electric motor or diesel engine and is capable of pumping water at a much higher pressure than a domestic water pump. A domestic water pump is designed to provide water pressure to a regular plumbing system for everyday use. It is usually powered by an electric motor and is capable of pumping water at a lower pressure than a fire pump.

After receiving the fire/pipe network pressure/power failure/other start signals, the diesel engine fire pump can automatically start and enter full load operation within 5 seconds. The battery can be automatically charged by the main power supply or the diesel charging motor to ensure the smooth start of the equipment; automatic alarm protection for low oil pressure, high water temperature and other faults of the diesel engine, overspeed alarm and shutdown; the diesel engine fire pump is in a hot engine standby state to ensure emergency work. The diesel engine fire pump adopts the direct connection technology between the diesel engine and the water pump. Through the elastic coupling, the failure points are reduced, the start-up time of the unit is greatly shortened, and the reliability and emergency performance of the unit are improved.

1. The performance of the fire pump should meet the flow and pressure requirements of the fire water supply system.
2. The power of the driver equipped with the fire pump should meet the requirements of the power required for operation at any point on the performance curve of the selected pump’s flow and lift.
3. When a motor-driven fire pump is used, a dry-installed fire pump with the motor should be selected.
4. The fire pump should be installed dry, and the pump should be placed outside the pool, and the submersible pump cannot be directly placed in the water for water absorption.
