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 DJ Fire Pump Set is a combination system consisting of a diesel engine pump and a jockey pump, designed for fire safety in the construction and industrial sectors. This system utilizes the powerful power output of the diesel engine pump, ensuring reliable operation even in the event of a power outage. The jockey pump maintains a constant water pressure, optimizing the performance of the fire suppression system. The DJ Fire Pump Set offers a reliable and efficient solution for prompt response to fire incidents, making it an essential component for protecting property and ensuring occupant safety.

The dual power fire pump is composed of a fire water pump, a double shaft extension motor and a diesel engine. One end of the output shaft of the double shaft extension motor is connected to the input shaft of the fire pump, and the other end of the output shaft of the double shaft extension motor is 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 driving circuit. With dual-power fire pumps, there is no need to configure a second fire pump, which reduces floor space and saves manufacturing costs.

Electric fire pumps are driven by electric motors, and are divided into horizontal, vertical and many other structural varieties. The electric fire pump set has a small footprint, light weight, low noise, and good start-up and operation performance. Although electric fire pumps have the advantages of simple operation and maintenance, most fire protection system design specifications stipulate that when electric fire pumps are used, they should have the conditions for dual-circuit power supply, and diesel engine fire pumps are usually used as backup pumps.

Jockey pumps help extend the lifespan of fire pumps by maintaining system pressure and preventing unnecessary cycling of the main fire pump. By handling minor pressure fluctuations and small leaks, jockey pumps reduce the wear and tear on fire pumps, which would otherwise start and stop frequently to maintain pressure. This reduced cycling minimizes mechanical stress on the fire pump’s components, such as bearings, seals, and impellers, thereby prolonging its operational life. Additionally, jockey pumps consume less power and operate more quietly than fire pumps, leading to energy savings and reduced noise pollution in facilities. By ensuring that fire pumps only operate during actual emergencies, jockey pumps contribute to the long-term reliability and efficiency of the fire protection system.

A fire pump is a critical component of a fire protection system. It is designed to increase the pressure and flow of water to ensure an adequate water supply for firefighting.

Fire pump is a general term for special pumps involved in water supply of various fire systems. The fire pump model is XBD. Fire pumps must be tested and approved by relevant national units before they can be used in various fire protection systems in buildings, such as: fire hydrant system, sprinkler fire extinguishing system, foam fire extinguishing system, large space high-altitude water cannon, water mist fire extinguishing system, rain shower fire extinguishing systems, water curtains, etc.

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.

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 an ultra-low pressure start-up device, the matching electric water pump control cabinet should also have an ultra-low-pressure start-up device, and the lower limit of the two pumps should have a certain pressure difference. Of course, according to customer requirements, design a control system that is more suitable for customer needs.

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.
