The Flexflo A3 peristaltic metering pump (photo) is designed to deliver smooth and gentle chemical feed for industrial water treatment without damaging long-chain polymers. In chemical treatment applications for industrial wastewater, the pump will accurately and consistently dose off-gassing chemicals, such as peracetic acid (PAA) and sodium hypochlorite (NaClO) with no vapor lock and no loss of prime. Additional A3 features include a 5-in. intuitive touchscreen display, which will respond even when the operator is wearing work gloves. The extra-large icons are easily recognizable and highly responsive. Because of the A3’s broad feed range and turndown ratio, users may be able to standardize operations on just one feed pump for all chemical dosing needs. Control methods for the pumps include manual, remote analog/digital, EtherNet/IP, Modbus TCP/IP and Profibus. — Blue-White Industries, Ltd., Huntington Beach, Calif.
