Metering-injection proportional mixing device
Category:
Product Overview
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.
