The inlet of multistage fire pump is on the inlet section in the horizontal direction, and the discharge outlet is vertically upward. The head can be adjusted by increasing or decreasing the number of pump stages. The product has advanced hydraulic models, high efficiency and wide performance range, smooth running and the low noise. The shaft seal is sealed by soft packing or mechanical seal. The seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick. The shaft is a full-sealed structure, ensuring contact with the medium without corrosion and long service life.

The diesel engine multistage fire pump is installed together with the electrical instrument and other equipment. It has complete functions, high degree of automation, compact structure, automatic fault alarm and receiving start signal. It can complete the start-up procedure by itself and can quickly put into full-load operation. The unit can be equipped with damper, rubber flexible joint and exhaust port with bellows silencer as required. In the case of insufficient fuel, low battery voltage, high lubricating oil temperature, overspeed, etc., an alarm device is provided to ensure diesel engine can start in the low temperature environment. The whole system is safe and reliable and easy to us.

Advantages of diesel engine multistage fire pump:
1. Powerful: The overall crankshaft of the diesel engine unit has high rigidity, high strength and high transmission torque efficiency.
2. Advanced technology: adopt international advanced technology and gantry-type body, sliding bearings, plate-fin type machine cooler, top-mounted heat exchanger, spin-on oil filter and dual cooling system.
3. Superior performance: The smoke and noise indicators reach the national superior products, and the fuel consumption is lower than the national standard superior products of 2.1g/kW.h.
4. High degree of automation: automatic, manual and fault self-check function, monitoring the working condition in the whole process, recovering the fault restart failure automatic restart function, automatic pre-lubrication, pre-heating, making the equipment start safer and more reliable; with central control room remote control functions, also with fieldbus connection (optional feature). The battery adopts automatic floating charge (constant current, constant voltage, turbulent charging) electric mode to ensure that the battery is in standby state at any time.
5. Easy to use: equipped with remote transmission instrumentation, can be connected to the control center according to needs, installation and use, easy maintenance.

The diesel multistage fire pump has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long service life and convenient installation and maintenance. For transporting clean water or other liquids with physicochemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive-containing media by changing the material of the pump's flow-through components, the form of the seal, and adding a cooling system.
