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.

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 equipment is suitable for fire water supply and emergency water supply in various occasions such as warehouses, docks, airports, petroleum, chemical, factories, power plants, liquefied gas, textiles, ships, cruise ships, etc.

Yes, fire pumps can operate in high-altitude locations, but their performance may be affected due to reduced atmospheric pressure, which can impact water flow and engine performance. It’s essential to select pumps specifically designed or adjusted for high-altitude use, ensuring they meet the required pressure and flow rates.

Fire pumps are necessary to maintain adequate water pressure for firefighting, especially in high-rise buildings, large industrial facilities, or areas with insufficient water supply.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, it can also be equipped with other diesel engines as power machines according to the needs of users.

Fire pumps are rated based on their capacity and pressure performance. The two key ratings are:

Gallons Per Minute (GPM): This rating indicates the pump’s flow capacity and how much water it can deliver per minute. It is essential to ensure that the fire pump can meet the specific flow requirements of the fire protection system.

Pressure (PSI): The pressure rating specifies the force with which the pump can deliver water. Sufficient pressure is critical for effectively propelling water through the fire sprinklers and hoses.

Understanding these ratings is vital when selecting a fire pump for a facility, as it ensures that the pump can meet the specific needs of the fire protection system.
