Fire pumps are necessary when the water supply available does not generate the necessary hydraulic pressure required to meet demand of a fire protection system such as automatic sprinklers and standpipes, or even foam systems.

A multistage pump is a multistage centrifugal pump in which two or more impellers are installed on the pump shaft and connected in series to work together. A horizontal multistage centrifugal pump refers to a multistage pump in which centrifugal pumps with two or more impellers are combined. The multistage centrifugal pump is characterized by high efficiency and energy saving, wide range of use, special purpose, stable operation, long service life, convenient installation and maintenance, etc.

500gpm, 5bar fire fighting pump, export to Greece.Duty pump is electric fire pump, diesel engine fire pump as standby.

Fire pumps work by drawing water from a water source (such as a storage tank or a dedicated water supply) and then increasing the pressure to deliver water through the fire sprinkler system or hoses. They are typically powered by electric motors or diesel engines.

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.

A typical firefighting pump system consists of the pump itself, intake and discharge hoses, nozzles, strainers or filters to prevent debris from entering the pump, and sometimes additional accessories like foam injection systems for enhanced fire suppression capabilities.

25≤Q≤100GPM
30≤H＜120m

The minimum fire rated pressure of EDJ small fire fighting package set water supply equipment is 3 bar, and the minimum fire rated capacity is 25 GPM. EDJ 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.
This pump machine unit is very sutitable for fire fighting or pressure-stablized purpose for house or small building.

Fire pumps are more expensive than ordinary water pumps because they must meet specific fire protection standards and are built to handle high temperature and pressure water. They also have additional features, such as larger motors, to rapidly provide the necessary flow rate to meet fire protection requirements.

The biggest problem in the event of a fire is to ensure continuous fire-fighting power. If the fire is not extinguished in time due to insufficient supply of raw materials, it will cause huge economic losses. Therefore, high-quality fire pumps must be selected to avoid quality problems. , resulting in irreparable damage.

The diesel engine fire pump set has the characteristics of good starting characteristics, strong overload capacity, compact and reasonable structure, convenient maintenance, simple and reliable use, etc. The unit is equipped with protection functions such as overspeed, low oil pressure, three start failures, high water temperature, low oil level, and low battery voltage. At the same time, it can be connected with the customer’s automatic fire alarm device or the fire control system control cabinet produced by our factory to realize the function of remote monitoring.

While firefighting pumps are specifically designed for extinguishing fires, they can sometimes be adapted for other applications, such as irrigation or water transfer, depending on the pump type and specifications.

A fire pump is part of the water supply for a fire sprinkler system and is powered by electricity, diesel or steam. It uses water from an external source to increase water flow and pressure. The pump inlet is either connected to a public groundwater supply line or to a static water source. The pump provides higher pressure water flow to the sprinkler system risers and hose risers. Fire pumps must be tested monthly and annually to ensure they are operating as designed. These two different tests are called the monthly “churn” test and the annual flow test.
