1. Characteristics of diesel fire pump
The biggest difference between a diesel fire pump and an electric water pump is that diesel pump has its own independent power supply system - the battery. Therefore, the start and operation of the diesel fire pump can be completely disconnected from the mains.

Diesel engine fire pumps are usually used as backup facilities, only when the fire signal comes, and the electric water pump fails or the power is cut off, the pump will start automatically. When there is a device with ultra-low pressure can start the pump, the matched electric water pump controller matched should also have a device with ultra-low pressure start pump, and the lower limit of the pump start should have a certain pressure difference. Of course, we can also design a control system that is more suitable for the customer's requirements.
