500GPM @ 70m DJ Fire Pump Set

These pumps ensure that a building’s fire protection system operates effectively during an emergency, providing the necessary water pressure and flow to control or extinguish fires, thereby protecting lives and property.

The fire pump unit 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 water pump, and the other end of the output shaft of the double shaft extension motor is connected to a One end of the 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.

The pump will start to work when the pressure in the fire extinguishing system pipeline of EDJ small Fire Fighting water supply equipment drops suddenly. The first triggered pump is the jockey pump(pressure stabili-zation pump). The pressure stabilization pipeline of the jockey pump is allowed to start frequently within a certain range. In general, the pressure of the jockey pump is 1-1.5 bar higher than that of the main pump.

The diesel engine fire pump is suitable for unmanned emergency water supply system.

The ED Dual-Power Fire Pump System combines electric and diesel engine pumps to ensure uninterrupted fire protection and a reliable water supply. In the event of power outages or electrical failures, the diesel engine pump seamlessly takes over, guaranteeing continuous operation of the fire protection system. This dual-power configuration offers both reliability and flexibility, providing comprehensive coverage for fire safety needs.

Diesel engine fire pumps are suitable for use in high lift and high flow fire water supply environments or as backup fire water supply pumps. The reason is that the diesel engine has strong power and can be used with large flow fire deep well pumps, and the diesel engine fire pumps have the characteristics of self-starting when power is off. Emergency water supply is available, so a diesel engine fire pump is a good choice.

For diesel-driven fire pumps, environmental considerations include proper fuel storage and spill containment measures. It’s important to adhere to environmental regulations to prevent pollution and ensure the safe operation of the pump.

Diesel pumps are suitable for fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, and textiles. Especially in the case of no electricity and dissatisfaction with the grid, choosing a diesel engine-driven water pump is the safest choice.

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.
