Stenner

When your pool needs an exact dose of chlorine or pH balancer, precision matters — and precision is what Stenner Pump Company has delivered since 1957. Founded by Gustav Stenner in Jacksonville, Florida, Stenner pioneered the peristaltic metering pump: a design that moves chemical through a flexible tube, so the liquid never touches moving parts, the pump stays self-priming, and there are no valves to clog. Privately owned since 1995 and veteran-owned, Stenner still manufactures in the USA, building most components from raw materials at its Jacksonville headquarters. Its pumps handle chlorine feeding, pH adjustment, and scale and corrosion control for pools, wells, and water systems across the country. For pool owners who want set-it-and-forget-it chemical automation backed by nearly 70 years of American manufacturing, Stenner is the industry standard.
