Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.

The diesel engine fire pump can deliver clean water below 80°C without solid particles or liquids with physical and chemical properties similar to water. Under the premise of meeting the fire protection conditions, the requirements of living and production water supply conditions are taken into account. The products can be used not only in independent fire-fighting water supply systems, but also in fire-fighting and living shared water supply systems, as well as in construction, municipal, industrial and mining, water supply and drainage, ships, field operations and other occasions.

Assess the water supply: Ensure availability and capacity of your building’s water source.
Identify the fire protection system needs: Consider sprinkler systems, standpipes, or hydrants.
Understand NFPA 20 standards: Choose UL-listed or FM-approved pumps for compliance.
Select the appropriate pump type: Electric, diesel, or jockey pump depending on power reliability and application.
Consider the building size and use: High-rises or industrial facilities require higher-capacity pumps.

Mechanical seals are commonly used on fire pumps to ensure reliable and long-lasting operation. These seals are designed to create a tight, reliable seal between the pump shafts, and the fire pump’s motor. Mechanical seals are typically composed of stationary and rotating components that move against each other with minimal friction, to form a mechanical seal that can withstand the stresses of the fire pump’s operation. In addition to preventing leaks, mechanical seals can help improve pump efficiency, reduce wear and tear on motor components, and increase the life of the fire pump.

There is a combination equipment that uses diesel as fuel for firefighting, but it is usually used as a backup firefighting facility, because it can only be started automatically when the firefighting signal comes, and the electric water pump fails or the power supply is cut off, that is, the diesel engine firefighting pump set. It is very different from the electric fire pump in that it has its own independent power supply and storage system.

The fire pump is mainly used for water delivery in the fire protection system. As an indispensable tool for the fire protection system, the fire pump has the characteristics of simple structure and stable performance. Due to these advantages of high performance and low energy consumption, the safety and efficiency of the fire pump are far ahead of the pipeline tools of the same purpose.

The minimum fire rated pressure of small fire fighting package set water supply equipment is 3 bar, and the minimum fire rated capacity is 25 GPM. ED small fire fighting package set water supply equipment includes at least two power or power source driven pumping units, pressure tanks, pipes, valves and accessories, measurement and control instruments, control cabinets, outdoor rain cover, etc.

CDL stainless steel vertical multistage pump is especially suitable for boiler feed water, and can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation, fire pressurization, hydraulic flushing, food, brewing, medicine, chemical industry, aquaculture , environmental protection, chemical process and machine tool supporting industries, as the power equipment for water supply and drainage.

A fire pump is installed to ensure an adequate and pressurized water supply for firefighting systems, such as sprinklers, standpipes, and hoses, in case of a fire emergency.

With the continuous progress of the times, the application of diesel engine fire pumps is becoming more and more extensive. Diesel engine fire pump is a common and necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. Diesel engine fire pump is installed together with electrical instruments, with complete functions, compact structure, automatic fault alarm, receiving start signal, and can automatically complete the start-up procedure and fast full-load operation. , Enough to ensure that the diesel engine fire pump is started in a low temperature environment, the whole system of the diesel engine fire pump is safe, reliable, and easy to use.

As a fixed firefighting equipment, diesel engine fire pumps are widely used in firefighting and shunting operations, especially when there is no power supply or no power supply (main power supply).
Diesel fire pumps can also be equipped with other diesel engines as power engines according to user needs. It is mainly composed of diesel engine, fire pump, connection device, fuel tank, radiator, battery, intelligent self-control panel, etc. The crankshaft of diesel engine fire pump has high overall rigidity, high strength and high torque transmission efficiency. Adopt international advanced technology, sliding bearing, plate-fin cooler, upper heat exchanger, rotary oil filter, double cooling system. Diesel engine fire pump performance, smoke and noise indicators meet national standards.

The fire pump set includes a main pump connected to the electric motor, a backup pump connected to the diesel engine, jockey pump, pressure vessel, controller for manual or automatic operation of the system and standard accessories mounted on the base.

The electric fire pump set is a fire pump powered by an electric motor, and generally consists of a set of fire pumps, electric motors, control cabinets and auxiliary devices. Because the electric motor fire pump set is composed of these parts, it forms a powerful fire protection and power effect, and provides a strong water source support for various fire hydrant systems and sprinkler systems in the building.

Fire pumps are the key to supplying fresh pressurized water to fire protection systems. They do not produce water per se, but add the energy needed to effectively extinguish a fire. These pumps can be connected to sprinkler systems or other external water sources near the emergency situation. Some may actually be connected to a well, reservoir or water body.

Choose the installation location: Ensure it’s a clean, ventilated, and non-flood-prone area.
Prepare a solid foundation: Use a robust concrete base to minimize vibration.
