The Coupled Water-turbine Driven Pump Proportioning Equipment is a hydraulically driven foam proportioning device that requires no external power source. It is specifically designed for accurate proportioning and mixing of foam concentrate and water in foam fire suppression systems.
When fire water flows through the proportioner, the built-in water turbine is driven by the hydraulic energy of the water stream. Through a mechanical coupling, the turbine drives the foam concentrate pump, which draws foam concentrate from the storage tank and injects it under pressure into the water stream. This process ensures continuous, stable, and accurate foam proportioning over a wide range of flow conditions.
With its compact construction, fast response, and high proportioning accuracy, the mechanical pump proportioner is widely used in fixed foam fire suppression systems and foam spray systems, and is recognized internationally as a mature and reliable foam supply solution.

• Required – Enhanced System Reliability
The system operates solely on hydraulic energy from the fire water supply and does not require electrical or pneumatic power, making it ideal for fire protection systems with extremely high reliability requirements.
• Stable Proportioning Over a Wide Flow Range
Through optimized matching of the water turbine and foam pump characteristics, the system maintains a consistent foam proportioning ratio across significant variations in water flow.
• Compact Design and Small Footprint
The integrated skid-mounted configuration facilitates transportation, installation, and maintenance, and is especially suitable for pump rooms or equipment rooms with limited space.
• Rapid Response and Instant Foam Supply
Foam concentrate delivery starts immediately with water flow, ensuring rapid formation of effective foam during the early stages of a fire.
• Proven Engineering Technology for Global Applications
The system is based on well-established technology and is easily integrated into internationally accepted foam system designs and standard engineering solutions.
The operating sequence of the Coupled Water-turbine Driven Pump Proportioning Equipment is as follows:
The fire protection system is activated and water enters the proportioning unit
The flowing water drives the internal water turbine
The turbine transmits mechanical power through a coupling to the foam concentrate pump
The foam pump draws foam concentrate from the foam storage tank
The foam concentrate is pressurized and injected into the fire water pipeline
Foam concentrate and water are mixed at the preset proportion to form a foam solution
The foam solution is delivered to discharge devices such as foam nozzles or foam generators for fire suppression
The entire process is fully automatic, requiring no manual intervention, and provides continuous and accurate foam proportioning.
