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.

Electric fire pumps are widely used in our production and life, such as in water treatment, fire safety and other departments. After the reform and opening up, it is widely used in life and production due to its characteristics of complete sealing, no leakage, and corrosion resistance.

Jockey pumps are smaller pumps that maintain pressure in the fire protection system between tests and activations. They prevent pressure loss in the system and ensure that the fire pump doesn’t start unnecessarily. Jockey pumps are crucial for system reliability.
