Blue-White’s® NEW FLEXFLO® A1F peristaltic metering pump will not lose prime, overheat in warm climates and does not require continuous maintenance. The A1F is ideal for use when metering off-gasing chemicals, such as sodium hypochlorite and peracetic acid. It maintains smooth chemical feed and will never loose prime. There are no check valves that could clog. The 1,000:1 turn-down ratio allows the user to standardize on one pump for all chemical feed applications. The large turn-down ratio capability is due to the energy-efficient, brushless DC motor. The motor runs cool and reduces power usage for a high-energy efficiency rating. Other features include: feed rates to 5.60 GPH (21.19 LPH), pressures to 100 PSI (6.89 bar), sealed weather-proof enclosure, patented Tube Failure Detection, wall- and shelf-mount brackets, heavy-duty, weather-proof display shield, self-adjusting power supply and a three-year warranty.
