The Chloritrol®

Valveless Chlorine Injection Pump System
The Pump That Never Loses Prime!

The Chloritrol® is a valveless metering system for accurate, maintenance-free injection of sodium and calcium hypochlorite for purification of municipal drinking water. Totally new patented technology & field tested, perfect for high and low demand applications, including Ultra Low Volume.

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.

In addition to the sanitizing of drinking water, the Chloritrol® is an excellent choice for accurate sodium hypochlorite addition for municipal swimming pools, water parks, resorts, food processing plants, and waste treatment applications.See what our customers are saying about our water and wastewater pump system  Bethpage Water District in Long Island.
