What Is a Fire Pump?

Fire pump is a kind of pump equipment specially used for fire fighting system, its main role is to provide sufficient water source and water pressure for fire fighting equipment to ensure that the fire can be quickly and effectively controlled and extinguished when the fire occurs.

Definition of fire pump

The fire pump is a special pump installed on the fire truck and fixed fire extinguishing system, which is used to transport liquid fire extinguishing agent such as water or foam solution.

What Is A Fire Pump?

Fire pump working principle

Through the diesel engine or other means to generate power, drive the transmission shaft operation, and then drive the impeller inside the pump to rotate at high speed, the external water or foam solution and other liquid fire extinguishing agent pressurized to the fire pipe network or directly transported to the fire source, to achieve rapid fire extinguishing effect.

Application of fire pump

Fire pump is widely used in all kinds of buildings, petroleum, chemical industry, mines, ports, ships and other places of fire water supply system.

Importance of fire pump

Fire pump is an important part of fire fighting system, its performance and reliability directly affect the effect of the whole fire fighting system.

Fire pump can provide stable water source and water pressure for fire fighting equipment, support the normal operation of fire fighting equipment, improve the efficiency of fire fighting, and reduce the loss of fire to personnel and property.

Features of fire pump

  • Fully sealed
  • No leakage
  • Corrosion resistance
  • Stable operation in complex and harsh environments
  • Different head and flow rates available

Classification of fire pump

Fire pump according to the application scenario and flow, head, there are generally some of the following categories;

Motorless fire pump

A fire pump without a power source that relies on the rotation of an impeller to transfer energy to a liquid.

Vehicle fire pump

An unpowered fire pump mounted on the chassis of a fire engine.

Marine fire pump

Fire pumps installed on ships, offshore work platforms, and water working environments.

Engineering-oriented fire pump

Fire pump for fire hydrant system, water spray fire extinguishing system, foam fire extinguishing system and other engineering sites.

Low pressure fire pump

Fire pump with rated pressure not greater than 1.6MPa.

Medium pressure fire pump

Fire pump with rated pressure between 1.8MPa and 3.0MPa.

High pressure fire pump

Fire pump with rated pressure not less than 4.0MPa.

Low and medium pressure fire pump

A fire pump capable of providing both medium and low pressure.

High and low pressure fire pump

A fire pump capable of providing both high and low pressure.

Water supply fire pump

Fire pump for fire water supply engineering.

Pressure maintaining fire pump

Engineering fire pump for stabilizing pipe network pressure.

Deep well fire pump

Engineering fire pump with vertical deep well pump.

Submersible fire pump

Engineering fire pump with submersible pump

Long shaft fire pump

The long shaft fire pump system is composed of a single or multiple centrifugal or mixed-flow impeller and guide shell, lifting pipe, transmission shaft, pump seat, motor and other components.
