Common types of fire pumps include the following:

Centrifugal fire pump: This is one of the most common types of fire pumps. They generate centrifugal force by rotating the impeller, suck the water source into the pump and throw it out at high speed to provide water source and boost pressure.

Diesel fire pump: A fire pump equipped with a diesel engine, usually used far away from power supply or in places where backup power is needed. They are suitable for emergency firefighting in the field or in case of power outage.

Electric fire pump: a fire pump driven by an electric motor, commonly used in fire protection systems in urban and industrial areas. They are reliable, stable, and easy to connect to urban power sources.

Water tank fire pump: usually installed in a water tank or pool, used for storing water and providing a fire extinguishing water source in the event of a fire. They are usually used in conjunction with the automatic control system of the fire protection system.

High pressure fire pump: a fire pump with a high pressure output, suitable for firefighting scenarios that require long-distance water supply or overcoming high resistance.

Foam fire pump: a fire pump used to spray foam extinguishing agent, suitable for special scenarios such as oil fire extinguishing, oil tank fire, etc.

Fire water gun pump: used to drive the fire water gun and directly spray it towards the fire point to extinguish the fire.

These fire pumps are usually selected and configured based on specific needs and application scenarios. The selection of fire pumps depends on factors such as fire extinguishing requirements, water supply conditions, site characteristics, and budget.
