The Flexflow A1F peristaltic metering pump (photo) is designed for metering off-gassing chemicals, such as sodium hypochlorite and peracetic acid. The pump offers a smooth chemical feed without risk that it will overheat or lose its prime. Furthermore, the pumps do not require continuous maintenance and do not include any check valves that could potentially clog. A large turndown ratio (1,000:1) allows users to standardize on one pump for all chemical-feed applications. Feedrates up to 5.6 gal/h (21.19 L/h) and pressures up to 100 psi (6.89 bars) are achievable. Other features include a sealed weatherproof enclosure, a patented tube-failure-detection functionality, mounting brackets and a self-adjusting power supply. — Blue-White Industries, Huntington Beach, Calif.
