Customizable 1.5kw Cast Iron Fire Fighting Sprinkler System Booster Pump

Daily pressure stabilization:

The fire-fighting network will cause the pressure to slowly drop due to micro-leakage of valves (such as 1%-3% of water leakage per day)1. When the pressure drops to the lower limit (such as P3=0.26MPa), the fire-fighting booster and pressure-stabilizing pump automatically starts to replenish the pressure; it stops 410 after rising to the upper limit (such as P4=0.31MPa).
The air pressure tank acts as a "pressure buffer": the internal rubber diaphragm isolates the air from the water, and the air bag expands to squeeze out the water to replenish the pressure when the network is depressurized, reducing the frequent start and stop of the pump (≤15 times per hour)15.

Fire emergency:

When a fire occurs, the fire hydrant uses a large amount of water, causing the pressure to drop sharply. When the pressure drops to the starting value of the fire main pump (P2=0.16MPa), the equipment instantly sends a signal to start the fire main pump, and the pressure-stabilizing pump stops at the same time. The 300L of water (about 30 seconds of use) stored in the air pressure tank ensures that the fire water is sprayed out as soon as possible to extinguish the golden fire
