The key idea is a dosing system designed specifically for hypochlorite solutions. When the equipment includes a solution tank to hold the liquid chlorine and a positive-displacement pump to meter a precise amount of that chemical into the water, you’re dealing with a hypochlorinator. The positive-displacement pump provides consistent, fixed-volume dosing with each stroke, which is essential for maintaining a stable chlorine residual. The tank supplies the hypochlorite solution to be dosed, completing the system.

Other terms describe parts or broader concepts. A chlorine feeder is a general term for any device that adds chlorine, not necessarily a complete tank-and-pump dosing system. A chlorinator can refer to equipment that generates chlorine or injects chlorine in different forms, not specifically a liquid hypochlorite solution with a tank and a positive-displacement pump. A dosing pump denotes just the pump component, not the full apparatus that includes the chemical reservoir.
