170JL4A1STAA Stenner 170DM4 Double Head Adjustable Pump 120V

Stenner 170JL4A1STAA Double Head Adjustable Output Chemical Injection Pump, 25PSI, 120GPD, 120V, 60 Hz,1/4W Santoprene If requiring more output than the Classic single head pump offers, especially with 25 psi installations for larger commercial swimming pools, then the double head pump may be your answer. Similar to the other models in the Classic series, the pump will dose solutions such as sodium hypochlorite, acid, polyphosphates, biocides for common water treatment applications that include disinfection, pH control, corrosion and scale control, oxidation and sanitization. Also utilized in water and wastewater treatment plants, the pump can inject two compatible liquids at the same ratio. The Classic Series double head fixed pump is built the same way as the single head fixed with the addition of another pump head that doubles the output. The pump runs at 100% fixed rate and can be installed to an ORP type controller to manage the output. The output is determined by three factors; the rpm of the motor gears, the setting on the feed rate control and the pump tubes in both heads. The feed rate control has an external dial ring that is labeled L to 10 offering an adjustable output of 5% to 100% in 2.5% increments.
