Types of fire pumps

The horizontal split case fire pump offers high flow capacity, double-suction design, low noise, and easy maintenance—making it the ideal solution for stable fire protection in modern buildings, industrial zones, and municipal projects. Discover its structure, performance, and wide-ranging applications.

The diesel engine fire pump and the electric fire pump are “one standby and one use”. The control boxes of the diesel engine fire pump and the electric fire pump should be kept independent of each other, and the diesel engine fire pump must be used as the backup pump of the electric fire pump, and cannot be used as backup for each other.

The pump start signal in the fire extinguishing system is directly connected to the electric fire pump control box, and it is not suitable to be connected to the diesel engine fire pump control box at the same time. The pump start fault signal of the electric fire pump control box and the pump start signal in the fire extinguishing system are used as the automatic start pump start signal of the diesel engine fire pump control box, and the line is connected to the control box of the diesel engine fire pump. The pump start failure signal of the diesel engine fire pump control box received an alarm from the fire control center. After receiving the alarm, the authorized personnel rushed to the pump room to force the diesel pump to start in an emergency.

Multistage centrifugal fire pump units enhance firefighting efficiency with high head performance, ideal for high-rise buildings, industrial zones, and long-distance water supply. Featuring high flow, energy efficiency, and smart monitoring, they ensure stable and reliable fire protection.

Diesel engine fire pumps are widely used in firefighting equipment due to their various advantages. Most firefighting equipment will choose to use this equipment, which has various automation functions and can be connected with other equipment according to customer needs. It is a kind of equipment with good starting characteristics, strong overload capacity, compact structure, convenient maintenance, simple use, and a high degree of automation.

Diesel engine fire pump sets are mainly suitable for fire water supply systems in petrochemical, natural gas, power generation, cotton and linen textiles, warehouses, airports, docks, high-rise buildings and other industries. It can also be used in occasions such as water ships, offshore oil tankers and fire fighting ships. The unit adopts imported diesel engine and fire pump. It has the characteristics of quick start, reliable water diversion, reasonable power reserve, stable operation, wide range of pressure and flow, etc. It is an advanced and reliable fire-fighting equipment.

As the core component of a fire protection system, the performance of fire pumps directly affects fire suppression efficiency. To ensure optimal performance, we maintain strict control over every stage, from design and manufacturing to installation and maintenance.

In the design phase, we utilize advanced fluid dynamics technology to optimize the pump structure, minimizing energy loss and maximizing water flow efficiency. The carefully designed impeller and flow channels enable the pump to maintain stable operation under high pressure while reducing noise and vibration, thereby extending its service life.

During the manufacturing process, we select high-strength, corrosion-resistant materials such as stainless steel and ductile iron to ensure durability in harsh environments. Precision machining and rigorous quality inspections guarantee that every fire pump meets industry standards before leaving the factory.

Proper installation is equally critical. Our professional team develops the best installation plan based on the site environment, ensuring tight pipe connections, smooth water flow, and stable electrical control system operation. The integration of intelligent control systems allows for automatic start-stop functions and remote monitoring, significantly improving response speed and operational convenience.

Finally, regular maintenance and inspection are essential for long-term efficiency. Our comprehensive after-sales services include routine inspections, spare parts replacement, and remote troubleshooting, ensuring the pump remains in peak condition.

Through scientific design, high-quality manufacturing, expert installation, and thorough maintenance, our fire pumps provide reliable fire protection solutions, helping to build highly efficient and secure fire suppression systems.

Efficient horizontal electric fire pump with compact design and stable performance, ideal for high-rise and commercial building fire protection systems.

Fire pumps have a wide range of uses. In addition to providing water for fire-fighting piping systems, they can also be used for industrial water delivery. Fire pumps can also be used for water supply and drainage systems in cities. There are also other relatively long-distance water delivery tasks, such as heating boilers, hot and cold water circulation pressurization of bathroom boilers and multi-stage fire pump furnaces, etc., can all be completed by means of fire pump systems.

Vertical long-shaft fire pumps are known for their high head, large flow rate, and stable performance, making them suitable for high-rise buildings, industrial parks, chemical plants, ports, and deep well water intakes. They feature a compact structure, small footprint, stable operation, corrosion resistance, and easy maintenance. They can also be driven by either electric or diesel engines to ensure continuous water supply, making them an ideal choice for ensuring the efficient and safe operation of fire protection systems.

The ED Dual-Power Fire Pump System combines electric and diesel engine pumps to ensure uninterrupted fire protection and a reliable water supply. In the event of power outages or electrical failures, the diesel engine pump seamlessly takes over, guaranteeing continuous operation of the fire protection system. This dual-power configuration offers both reliability and flexibility, providing comprehensive coverage for fire safety needs.

Diesel fire pumps offer distinct advantages over other types of fire pumps, such as electric or jockey pumps. Unlike electric pumps, which rely on grid power and may be vulnerable to power outages, diesel fire pumps can operate independently, making them suitable for use in areas with unreliable electricity or during emergencies. Jockey pumps, on the other hand, are typically used to maintain pressure in fire sprinkler systems but may not provide the same flow rates or firefighting capacity as diesel fire pumps.

A fire pump system typically includes the pump itself, a driver (usually an electric motor or diesel engine), a controller, and various accessories like suction and discharge piping, check valves, and pressure gauges.

The application of fire pumps is not only in fire protection systems, but a variety of fire pumps are gradually showing their superior strength in industrial production and urban construction. This includes the implementation and expansion of high-end technologies for industrial and urban water supply and drainage, and high-rise water supply under pressure.

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.
