Water treatment is a chemical-intensive industry. Every process node relies on precise chemical dosing, ranging from coagulation and sedimentation at municipal water plants, acid-alkali neutralization in industrial wastewater stations, to scale inhibition and sterilization for reverse osmosis (RO) membrane systems. However, conventional metering pumps often fail to cope with the following harsh operating conditions:
▸ Highly corrosive chemicals: Strongly corrosive media including sodium hypochlorite, sulfuric acid, sodium hydroxide and hydrochloric acid impose stringent material requirements on pump bodies. Diaphragm rupture and premature aging of diaphragms are recurring failures.
▸ Stringent dosing accuracy: Scale inhibitors are typically dosed at merely 2~5 ppm, while PAM flocculants are prepared at a concentration of 1~5‰. Minor flow deviations will either trigger excessive effluent pollutant levels or cause massive chemical waste.
▸ Wide viscosity range: Viscosity of polymer PAM flocculant solutions can reach hundreds of mPa·s, whereas sodium hypochlorite solutions are nearly water-thin. A single pump model rarely covers both extremes.
▸ Reliability for non-stop operation: Water treatment facilities run 24/7 without interruption; any pump shutdown results in process breakdown, demanding outstanding durability and extended maintenance-free service cycles.
▸ Tightening environmental compliance standards: The National 14th Five-Year Plan for Energy Conservation and Emission Reduction has raised higher bars for industrial water efficiency and pollutant discharge. Chemical dosing accuracy directly determines stable compliance with discharge limits.
All these challenges point to one common demand: the water treatment sector requires a fluid transfer solution with superior metering precision, stronger corrosion resistance and longer maintenance-free lifespans.
