There are several types of fire pumps, each designed for specific applications. Two common categories are centrifugal and positive displacement pumps.

Centrifugal pumps are widely used in fire protection systems due to their simplicity and reliability. They work by imparting kinetic energy to the water, which then exits the pump under pressure. These pumps are well-suited for maintaining consistent water pressure for fire suppression.

Positive displacement pumps, on the other hand, use a different mechanism. They trap water in a chamber and then force it into the discharge piping, creating pressure. Positive displacement pumps are typically used in situations where high pressure or low flow is required.

The choice of pump depends on the specific needs of the fire protection system and the facility it serves.

ZJBetter provide three types of fire pump system, such as diesel engine fire pump set, electric driven fire pump set, EDJ fire pump set.

Standardized open-frame diesel fire pump units have the advantages of open structure, convenient installation, simple maintenance and independent power, and are suitable for industrial and building fire protection systems to ensure stable water supply in emergency situations.

A fire pump starts when the pressure in the fire protection system drops below a set threshold, indicating water flow caused by sprinkler activation or manual use of a fire hose. The pressure drop is detected by pressure-sensing devices, triggering the fire pump to activate and provide adequate water pressure.

Double power fire pump is mainly composed of electric fire pump, diesel fire pump and regulator pump, in no power supply or power supply (mains) is not normal will start the diesel fire pump, to ensure the fire water supply in these unexpected circumstances.
