Suction and Discharge Connections on fire pumps

Diesel engine fire pumps can be widely used in environmental protection, water treatment and fire protection departments to transport various liquids by using their own advantages.

Building occupants should receive training on the location and proper use of firefighting equipment, including fire pumps. Regular drills and educational sessions contribute to increased awareness and preparedness during a fire emergency.

Fire pump refers to a clean water pump used for fire water supply, and a single water pump with a non-corrosive treatment medium temperature below 80°C. The pump unit is a joint operation of multiple fire pumps to ensure the quantity and stability of water supply. The electric motor fire pump set adopts multiple fire water pumps powered by electric motors. The general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption.

Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity or diesel. The pump inlet is either connected to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). This pump provides higher pressure water flow to sprinkler system risers and hose risers.
Our factory can manufacture NFPA20 compliant fire pumps.
Fire pumps can function with electric motors or diesel engines, and if local building codes require electricity independent of the local grid, pumps using electric motors can use the installation of an emergency generator when connected through a transfer switch listed.

It depends on the type of fire pump and the specific design of the system. Generally speaking, most fire pumps should be set to automatic mode in order to ensure that they operate when needed. However, in some cases, manual mode may be more appropriate and necessary.

2. High-rise building partition fire water system, fire and living, production and shared water supply system and buildings, municipal, industrial and mining, boiler water supply and other occasions.
3. Fire-fighting system pressurized water supply, water supply plants, irrigation, drainage pumping stations, power stations, air-conditioning circulating water, industrial water supply systems, fire-fighting systems, shipping industry, oil refining systems, mining and other liquid transportation.
4. Fire water supply and emergency water supply in docks, warehouses, airports, petroleum, chemical, power plants, liquefied gas, textiles, ships, oil tankers, etc.

Electric Pumps:Electric pumps can use vertical in-line pumps,horizontal end-suction pumps,vertical multi-stage pumps,horizontal multi-stage pumps,split casing pumps and so on according to the different flow andhead of customers.

Diesel engine fire pumps can be used for fire water supply in warehouses, docks, airports and other places. We usually choose the appropriate diesel engine fire pump model application according to the head, flow rate, power, medium properties, required materials, etc. provided by the user. In order to avoid mistakes, the loss caused by the installation environment will also be considered comprehensively to ensure stable and reliable efficiency.

What is a jockey pump? While its name may remind you of one of those little guys that tells a race horse where to go, a jockey pump is actually used to maintain a high pressure in a fire suppression system.

The EJ (Electric pump + Jockey pump) Dual Power Fire Pump System is an innovative and reliable fire protection solution. Combining an electric pump for robust water pressure and flow with a top-quality jockey pump for stable pressure maintenance, this system ensures efficient and timely water supply during fires. With advanced automation, remote monitoring, and energy-saving features, the EJ Dual Power Fire Pump System is a trusted choice for commercial, industrial, and residential applications.

This fire pump set is composed of diesel pump and stabilized pump. It adopts IS pump, which has advantages in price and is not affected by mains electricity. It is suitable for warehouses, docks, airports, petrochemicals, power plants, liquefied gas, textiles, ships , oil tankers and other fire-fighting occasions.

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 fire pump unit can be classified according to the following rules:
1 according to the form of power source, it can be divided into:
A) diesel engine fire pump unit
Motor fire pump unit
C) gas turbine fire pump unit
D) gasoline engine fire pump unit
(2) it can be divided into:
A) water supply fire pump unit
Stabilized pressure fire pump unit
C) hand lift motorized fire pump unit
3. According to the auxiliary characteristics of the pump unit, it can be divided into:
A) common fire pump unit
Deep well fire pump unit
C) submersible fire pump unit
The above is the basic classification, but various types can be combined with each other, such as medium and low pressure fire pumps, high and low pressure vehicle fire pumps, ordinary fire pump sets, electric submersible fire pump sets, etc

Single-stage fire pumps have only one impeller, and multistage fire pumps can have two or more impellers. Because the pump core in them is different, the structure is different. The impeller of the multi-stage pump is more than that of the single-stage pump, which can achieve a larger head at the same flow rate. The multi-stage pump is the sum of the single-stage pumps, and the head and outlet pressure can be made very high.

The EJ Dual Power Fire Pump System is an innovative and reliable fire protection solution. Combining an electric pump for robust water pressure and flow with a top-quality jockey pump for stable pressure maintenance, this system ensures efficient and timely water supply during fires. With advanced automation, remote monitoring, and energy-saving features, the EJ Dual Power Fire Pump System is a trusted choice for commercial, industrial, and residential applications.

Fire pumps are often integrated with fire alarm systems to provide automatic alerts in case of pump activation or failure. This integration ensures that building occupants and emergency responders are immediately informed during a fire event.

Floating impeller axial force tone- balancing device
The balancing slice device has two gaps, the radial gap behind the impeller and the axial gap of the balancing slice, because of these two gaps, the balancing slice can automatically acclimate the axial l gap to achieve automatic balance of axial force, and the tableware rotor is in a floating state.

The principle of the balance plate is scattered to the impeller, the impeller back mouth ring radial concurrence below the axial concurrence, this device that’s the same as the balance plate, the conformation of two gaps, only in a different position. Because the impeller has these two gaps to round each other, so that the impeller can also achieve automatic balance of axial forces.

While the primary purpose of fire pumps is firefighting, some systems may incorporate them for other water supply needs, such as industrial processes or water distribution. However, their design and functionality are optimized for firefighting applications.

Diesel engine fire pump is a kind of mechanical and electrical integration equipment that is directly driven by diesel engine fire pump and can start and complete water supply in a short period of time. Diesel engine pumps are driven by diesel and do not need an external power supply. Diesel engine water pumps are suitable for various fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, textiles, etc., especially where there is no electricity, When the power grid is not satisfactory, it is the safest choice to use a diesel engine to drive the water pump.
