Boost Your Fire Protection with EDJ FIRE PUMP SET

Water hammer in fire pump systems with high flow rates is mitigated by incorporating surge suppressors, check valves, and properly designed piping configurations. These measures prevent sudden pressure changes and protect pump components.

In fire protection systems, various types of fire pumps are used. Fire pumps are classified as horizontal split case, vertical split case, vertical in-line, vertical turbine, or end suction. These fire pumps may be powered by an electric motor, a diesel engine, or on rare occasion powered by a steam turbine.

Our company’s fire pump equipment is widely used in state agencies, various residences, pressurized pump stations, hotels, schools, hospitals, etc. due to its outstanding features such as environmental protection, energy saving, and safety.

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.

In order to match the service cycle of the fire pump, the inspection of the diesel engine and the fire pump should be regularly checked, and the parts to be replaced or repaired should be adjusted and corrected in a timely manner. We need to check the fuel tank reserves and oil quality of the diesel engine fire pump every day; the usage of the battery; the cooling system, etc., the pump shaft, impeller, bearing, and the wear of the water pipe and filter screen of the water pump. (Diesel engines of different brands may be different, and should be checked and maintained according to the specific model and structure of the diesel engine).

Electric fire pump: It is an important part of the fire water supply system. Divided into ordinary type and foam type. The ordinary type is used for general fire water supply; the foam type is equipped with an adjustable proportion mixer and a cam pump, which can deliver the mixed liquid to various foam launching devices to extinguish various oil fires. The electric fire pump consists of two parts, the motor and the pump. The pump and the motor are coaxial. The pump structure includes pump body, rotor, pump cover, mechanical seal and other components.

The EDJ fire pump unit consists of a fire pump, a double-shaft motor and a diesel engine. One end of the output shaft of the double-shaft motor is connected to the input shaft of the fire pump, and the other end of the output shaft of the double-shaft motor is connected to the One end of a clutch is connected, and the other end of the clutch is connected with the output shaft of the diesel engine. The fire water pump, the double-shaft extension motor, the clutch and the diesel engine are all fixed on the base. The double shaft extension motor, the clutch and the diesel engine are respectively electrically connected with a control circuit through an action drive circuit. With dual-power fire pumps, there is no need to configure a second fire pump, which reduces floor space and saves manufacturing costs.

In cold climates or areas prone to extreme weather, fire pumps face unique operational challenges that require careful design and maintenance. Freezing temperatures can cause water to freeze in the pipes, potentially damaging the fire pump and other components of the fire suppression system. To mitigate this, fire pumps may be installed in heated enclosures, and antifreeze solutions or dry-pipe systems are often used to prevent freezing. Jockey pumps help maintain system pressure, but in extreme weather, they must be monitored closely to ensure they don’t overcompensate for changes in pressure caused by temperature fluctuations. High winds, flooding, or snow accumulation can also impact the performance of fire pumps, especially in outdoor or exposed installations. Ensuring that fire pumps have robust weather protection, backup power supplies, and regular winterization procedures is critical for maintaining their reliability in harsh conditions. Additionally, these pumps should be designed with durable, weather-resistant materials to withstand long-term exposure to extreme environmental factors while still delivering dependable fire protection.

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.
