Stenner 45MFL4A3SUAA Classic 45 Fixed Output Pump – 35 GPD, 25 PSI, 120V

45MFL4A3SUAA — Stenner Classic 45 Series Single Head Fixed Output Metering Pump, 35 GPD, 25 PSI, 120V.

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 45 Series Fixed pump runs at a single, non-adjustable output set by its motor speed and pump tube size, which makes it a dependable choice for proportional feed installations activated by a water meter or controller, or for pool sanitation systems where ANSI/NSF 50-listed dosing is required. 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.
