Product Features:
Adopting high-strength steel frame structure design to ensure stable and reliable equipment
Configure an independent pressure sensing system, with dedicated pressure sensing lines for each controller
Unique suction pipeline design, without filter to ensure smooth flow path
Configure efficient check valve and butterfly valve combination to ensure precise fluid control
Strictly follow NFPA 20 standard to ensure the safe operation of the pump unit under various working conditions

Working Principle:
This system adopts intelligent pressure control mode:
When the system pressure drops to the set value, the pressure switch triggers a signal
Start the spare pump immediately and run continuously for 10 minutes to restore system pressure
If the pressure continues to decrease, the main pump will automatically start and put into operation
When the system pressure cannot be maintained, the backup pump will take over the operation to ensure the continuous supply of pressure to the system

Application Scenario:
This series of fire pumps is widely used in:
High rise building fire protection system
Petrochemical plant
Large public facilities such as airports and stations
Factory enterprise fire protection system
Urban fire water supply system
