Stenner 170JH2B4STAA Classic 170 Double Head Adjustable Pump – 34 GPD, 100 PSI, 220V

170JH2B4STAA — Stenner Classic 170 Series Double Head Adjustable Metering Pump, 34 GPD, 100 PSI, 220V.

Stenner's Classic Series is the pump line that built the company's reputation: a simple, electromechanical peristaltic design that has been in continuous production for decades because it works and it's easy to service. The patented roller-and-tube pump head keeps the solution completely isolated from the motor and gearing, so there are no seals, valves, or check balls to wear out or clog. The pump is self-priming against full working pressure, won't lose its prime or vapor-lock on off-gassing chemicals like sodium hypochlorite, and can run dry without damage. The 170 Series is Stenner's highest-capacity double-head Classic pump, pairing two independent heads on one motor for up to 170 gallons per day of combined output or matched dual-chemical dosing. An external feed-rate dial adjusts both heads together from roughly 5% to 100% of rated capacity. It's the standard choice for well water chlorination and disinfection, pH correction, iron and manganese oxidation ahead of a filter, corrosion and scale control, and commercial pool and spa sanitation, and is also widely used in cooling towers, irrigation, animal health, and industrial process water.
