Water Driven Pump Proportioner

The Water Driven Pump Proportioner mixes foam concentrate into a firefighting water stream, using the water flow itself to power the dosing pump. As water passes through, it drives an internal piston that draws concentrate from a supply tank and injects it at a set ratio. This removes the need for a separate engine or motor to run the proportioning system. Additionally, the mixing ratio adjusts through a dial, matching concentrate use to the fire type and foam specification.

Fire departments in Pakistan use this proportioner during structure fires where foam improves suppression on flammable materials. Similarly, industrial fire brigades at refineries rely on the device for rapid foam application during fuel or chemical fires. Airport fire and rescue teams also use proportioners during aircraft incident response, where foam plays a central role. Furthermore, municipal water tankers equip these units to support foam operations at sites without a fixed hydrant.

The unit connects between the hose line and discharge nozzle, so crews add foam capability to an existing setup. As a result, departments upgrade water-only equipment without a new pump system. A bypass valve lets crews switch back to plain water mid-operation if foam runs out. Consequently, firefighting continues without a pause to reconfigure equipment.

Tactical Supply Pakistan supplies this proportioner to fire departments, industrial safety teams, and airport rescue services nationwide. In contrast to powered proportioning systems, the water-driven design needs no separate fuel or electrical supply. Finally, its rugged construction withstands repeated use during emergency response operations.
