A horizontal fire pump has its shaft aligned horizontally, making it suitable for installations with more floor space. A vertical fire pump, on the other hand, has a vertical shaft and is ideal for spaces with limited floor area but sufficient vertical space. The choice between horizontal and vertical configurations depends on the available space, system layout, and design preferences.

Diesel pumps can be combined with electric pumps, jockey pumps, etc. to form an automatic water fire-fighting water supply system, and can be linked with the fire control center.

When the pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set to start the motor to start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine to the rated speed . The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the pump set receives a signal that the pressure of the pipeline network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

The fire pump is actually a pump that needs to be used in fire protection. According to different classification methods, it can be divided into different types of pumps.
