Blue-White Industries FLEXFLO High Pressure Metering Pump with Analog Timer 115V 60HZ | A1N20A-7T

Description

Delivers precise chemical dosing up to 76.1 gallons per day without the mechanical check valves that routinely clog or fail in conventional metering pumps. The Blue-White Industries FLEXFLO A-100NA (A1N20A-7T) pairs a fixed 45 RPM continuous-duty motor with a tactile analog dial, giving operators direct, repeatable control over feed rates for commercial pools, spas, and industrial water treatment lines.

Rather than relying on moving seals, this peristaltic design compresses a 7/16-inch Flex-A-Prene 7T pump tube to push fluid forward. The valve-free architecture eliminates vapor lock, maintains prime against backpressure, and securely handles working pressures up to 50 PSI. If the tube reaches end-of-life, integrated failure detection instantly cuts motor power to prevent uncontrolled chemical release.

Running on standard 115V AC/60Hz power, the unit operates behind a weather-resistant NEMA 3R / IP23 housing. Adjusting output simply requires rotating the timer base to set any pump-on duration between 3 and 60 seconds within each repeating sixty-second cycle, translating cleanly to a 3.976.1 GPD range (maximum 3.17 GPH / 200 mL/min). The system lifts chemicals suction-side up to 30 feet and safely processes fluids rated to 130F and 5,000 cP viscosity.

This configuration replaces aging diaphragm units in chlorine and acid feed applications where consistent injection timing matters. Confirm your exact daily dosage requirement, maximum system pressure, and vertical lift before connecting; ensuring full chemical compatibility between the pump tube, fittings, and storage tanks extends component life significantly. The manufacturer supports the A1N20A-7T with a one-year limited warranty when installed following published electrical and plumbing specifications.
