Double Motor Drive Foam Pump Proportioning System
The Double Motor Drive Foam Pump Proportioning System is a cutting-edge fire protection system designed to deliver precise and reliable foam concentrate proportioning across a wide range of flow rates and pressures. This system is particularly suited for industrial, marine, and fixed fire suppression installations where accuracy, durability, and adaptability are critical for effective fire control..

Key Components and Functionality
01/
Dual Motor Configuration:
- The system employs two motors (typically electric and diesel-driven) to ensure redundancy and uninterrupted operation. This dual-motor setup enhances reliability, allowing the system to function even if one motor fails, making it ideal for high-risk environments.
- The motors drive positive displacement pumps (e.g., gear or plunger pumps), which are engineered to deliver consistent foam concentrate flow regardless of variations in water pressure or demand
.
02/
Foam Concentrate Pumping:
- The pumps pressurize the foam concentrate from an atmospheric storage tank and deliver it to the proportioning device.
- The system is capable of handling various foam types, including Class A (for ordinary combustibles) and Class B (for flammable liquids), with proportioning ratios ranging from 0.1% to 10%.
03/
Proportioning Device (Ratio Controller):
- A modified venturi device or a precision ratio controller mixes the foam concentrate with water at the predetermined ratio.
- The proportioner is designed to fit into standard piping systems and operates effectively across a wide range of flow rates, ensuring accurate foam induction even under fluctuating conditions.
04/
Pressure Balancing Mechanism:
- The system incorporates a pressure-balancing diaphragm valve that automatically adjusts the pressure of the foam concentrate to match the water supply pressure at the inlet of the proportioner.
- This ensures balanced pressure between the foam and water lines, eliminating the need for manual adjustments and maintaining consistent foam quality.
05/
Control and Monitoring:
- The system is equipped with duplex pressure gauges to monitor the pressures of both water and foam concentrate at the inlet of the proportioner.
- Advanced control systems (e.g., microprocessor-controlled units) allow for automatic operation, real-time monitoring, and adjustments to foam proportioning rates based on water flow fluctuations.
06/
Skid-Mounted Design:
- The entire system is pre-assembled on a structural steel base, making it easy to install, relocate, and integrate with existing water supply infrastructure.
- The skid-mounted design enhances portability and stability, especially in marine or industrial environments.
