Fluid Metering (USA) is proud to have received a patent for their NEW Chloritrolâ„¢ valveless metering system for accurate, maintenance-free injection of sodium hypochlorite for purification of municipal drinking water.
Accurately metering liquid sodium hypochlorite presents a unique challenge because of the fluid’s tendency to out-gas. Many conditions including elevated temperatures, exposure to UV radiation, and cavitation, in addition to, contact with metallic and organic impurities, tend to increase sodium hypochlorite out-gassing.
The resulting gas bubbles present a condition known as “gas lock†which adversely affects the efficiency and accuracy of the injection pump’s output. This, in turn, can significantly reduce the amount of chlorine added, and in the worst case, cause the pump to completely lose prime.
The Chloritrolâ„¢ System is a unique valveless duplex pump design. The first pump head is high pressure and injects the sodium hypochlorite directly into the water main. The second pump head functions to remove out-gas bubbles from the inlet side of the high-pressure pump head.
