Stenner Pump 85mfl5a1suaa Metering Pump 85 Gpd 120V

Product Description

The STENNER PUMP 85mfl5a1suaa is a fixed-rate, single-head peristaltic metering pump rated at 85 gallons per day (GPD) and 25 psi, operating on 120 volts. It belongs to the Classic Series line and is designed for precise, repeatable chemical dosing in water treatment and pool sanitization applications. The motor and pump head are two separable components that detach without tools, simplifying inspection and routine service. ETL tested and conforming to ANSI/NSF Standard 50 when paired with listed controllers, this pump delivers a consistent feed rate suited to both residential and commercial aquatic environments. Licensed plumbers, pool service technicians, and water treatment professionals are the primary installers.

This pump is well suited for commercial and residential pool sanitization systems, pH regulation, oxidation, corrosion inhibition, and scale control. It is designed to pair with a compatible controller to form a complete chemical feed and sanitization system. The fixed single-speed pump head delivers a steady output rate, making it appropriate for applications that require consistent chemical injection without variable-speed adjustment. Pool Type noted in supplier data is listed as Commercial Pool, indicating suitability for higher-demand aquatic environments where dosing accuracy and uptime are critical.

Compatibility

Designed for use in commercial and residential pool water treatment systems. ETL listing and ANSI/NSF Standard 50 conformance apply when operated with compatible listed controllers. Suitable for chemical feed applications including chlorination, pH adjustment, and oxidation treatment.

Installation Notes

Installation should be performed by a licensed pool service technician or qualified water treatment professional familiar with chemical metering equipment. Shut off power to the system and isolate chemical supply lines before servicing the pump head or motor. Follow applicable local codes and NSF Standard 50 requirements when integrating into a pool sanitization system. Use only chemically compatible tubing and fittings rated for the solution being dosed.
