Metering-injection proportional mixing device


Product Overview

A high-precision metering pump injects the foam concentrate, maintaining a constant mixing ratio that is unaffected by flow rate.

Product Details


Product Features: A high-precision metering pump injects foam concentrate, ensuring a constant mixing ratio that remains unaffected by flow rate.

Fire suppression principle: The metering pump delivers a precise liquid dosage, which is accurately blended with the main water flow to form a mixed solution.

Basic components: Metering pumps, controllers, atmospheric-pressure tanks, sensors, and pipeline valves

Application scenarios: Petrochemical facilities, terminals, airports, large-scale foam fire suppression systems, and high-precision proportioning areas

Product Advantages: Extremely precise mixing ratio, flow‑rate self‑adaptation, long service life, and simple maintenance.
