Flowrox Chemical Metering Pumping Systems
Flowrox Chemical Metering Pumping Systems™ has engineered pump packages designed for easy installation and startup.

Flowrox Packaged Chemical Feed Systems are designed for water and wastewater treatment facilities. They are equipped with simple site connections to ensure ease of installation and start-up on site. They combine Flowrox metering pumps with thermoplastic containment skids. The system is packaged and tested with integral piping, valves, fitting, gauges, and connection fittings.
Chemicals are added at a controlled rate with positive displacement hose (peristaltic) pumps. Flowrox package chemical metering systems have revolutionized chemical dosing by providing pre-engineered and fully customizable packaged systems.
Water treatment uses include disinfection, injection of peracetic acid, fluoride treatment, sodium bisulfite metering, sulfuric acid dosing, sodium hypochlorite systems, polymer dosing, sodium hydroxide feed, potassium permanganate dosing, coagulation & flocculation, hydrochloric acid metering, alum feed, neutralization, and anti-scaling chemicals.
Wastewater uses include disinfection, sodium hypochlorite feed, polymers, coagulants, flocculants, defoaming chemicals, filter aids, odor control chemicals, neutralization, sludge conditioners, activated carbon, lime slurries, oxidizing and reducing agents, ferric chloride, ferric sulfate, calcium chloride, aluminum chloride, aluminum sulfate, soda ash, caustic soda, etc.
Wall mount packaged systems maintain minimal space requirements while providing easy inlet and discharge connections. It ensures improved safety with an integrated spill containment basin built into the packaged system. The wall-mounted packaged pumping systems provide reliable dosing operation using peristaltic (hose) pumps.
The Flowrox chemical metering pumping systems are available in simplex (one pump), duplex (two pumps), triplex (three pumps), or quadruplex (four pumps) configurations with a wide range of pump options, piping arrangements, and materials. Our technical expertise in engineered system design will help you develop easy-to-install solutions for your chemical dosing applications.
