This vertical pipeline fire pump, designed for industrial and civil fire protection projects, features a compact vertical structure and efficient hydraulic design. It boasts rapid start-up, stable operation, high head, and continuous water supply capacity, making it suitable for fire hydrant and sprinkler fire protection systems and meeting the fire water supply needs of various buildings.

1. Diesel pump: the flow rate is the same as that of the electric pump. It connects pump sets with highly elastic couplings or universal joints.
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.

High-lift fire pumps possess powerful high-pressure water supply capabilities and excellent operational stability, specifically designed for high-rise buildings, industrial facilities, and long-distance water transmission systems. Their high-efficiency impeller structure, corrosion-resistant materials, and intelligent control system ensure a continuous and stable fire water supply.

The full name of diesel engine fire pump is engineering diesel engine fire pump set, which can be automatically charged, automatically started, and has the functions of automatic alarm and automatic preheating. The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

There are many types of fire-fighting equipment, fire hydrants and fire extinguishers are a common category, and there is also a category of fire pumps, which can be described as the heart of the fire-fighting system and play an important role in pressurising the water supply for the fire-fighting system. Among the many fire pump products, fire pumps can be divided into multi-stage and single-stage fire pumps.

Multi-stage pumps have high efficiency, corrosion resistance, reliable operation and other properties, strong bearing capacity of the pump body, strong resistance to overload and more sensitive start. Ltd. introduces you to the relevant features of multi-stage pumps. First of all, Shanghai Xizhiquan multi-stage pumps have a compact structure, with small spacing between parts and small volume. The equipment runs smoothly, has a long service life and produces less vibration during operation, so the practical life of the equipment is correspondingly long.

With its unique structure, the direction of the water inlet and outlet can be adjusted according to different needs, so it is suitable for various place environments. The direction of the inlet and outlet is horizontal, which reduces the number of bends in the pipeline connection, thus simplifying the pipeline connection and greatly enhancing the efficiency of the fire fighting system.

The efficient operation of the multistage pump is used in many larger, more demanding fire-fighting locations. Its role is mainly to play a role in the fire fighting pipeline system to pressurise and send water, multi-stage pumps are not only suitable for all kinds of fire fighting systems, but also for industrial drainage, high-rise building water pressure supply, long-distance water delivery, water circulation pressure and other occasions.
