An efficient and accurate method of pumping fluoride into a municipal water treatment distribution system.  Tube life averages 9500 hours in this low pressure application.
Water fluoridation is the controlled addition of fluoride to a public water supply to reduce tooth decay as specified by the Center for Disease Control and Prevention. It is estimated that about two-thirds of the US population uses water that has been fluoridated from our municipalities. In stark contrast, only about 6 percent of the world’s population drinks fluoridated water.

The precise control of fluoride levels is paramount to health and safety of the public. Even with slightly above average recommended amounts of fluoride, though not considered dangerous, can lead to discoloration, unpleasant odor and taste in the city’s water supply. In the United States the optimal level of fluoridation ranges from 0.7 to 1.2 mg/L (milligrams per liter, equivalent to parts per million), according to the Center for Disease Control and Prevention. Depending on the average maximum daily air temperature; the optimal level is lower in warmer climates, where people drink more water, and is higher in cooler climates.

The World Health Organization cautions that fluoride levels above 1.5 milligrams per liter can increase the risk of fluorosis. Consumption of water exceeding 10 mg/L fluoride has been shown to lead to pathological changes in bone structure, and skeletal fluorosis. It is critical that the injection of fluoride be as precise and consistent as possible.
