Fire pumps generally use three driving forces, including diesel engines, gasoline engines and electric motors. Gasoline engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient.

1. Electric fire pump: various end suction pumps and split pumps.
2. jockey pump: vertical, small flow, higher lift than electric or diesel pumps.
3. Control panel: Automatically control the water pump with overload and overcurrent protection.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, flexible expansion joint, pressure switch, pressure gauge, base, etc

The two main starting and control methods for fire pumps are manual starting and automatic starting.

Manual Starting: Manual starting is the simplest and most commonly used method for starting a fire pump. It involves the use of a manual start switch or lever to start the pump motor.

Automatic Starting: Automatic starting is the most reliable method for starting a fire pump. It involves the use of a control panel, which can be programmed to start the pump motor when a drop in pressure is detected. The control panel also monitors the pump’s performance and can be used to shut off the pump if it fails to start or is not performing properly.
