Blue-White FLEX-PRO A4 ProSeries Peristaltic Pump
Advanced chemical metering with precise control and durable construction.
The Blue-White FLEX-PRO A4 ProSeries Peristaltic Pump is designed for high-performance chemical metering in industrial applications, offering superior precision and reliability. This pump is self-priming, capable of handling maximum line pressure without the need for by-pass valves, and eliminates vapor lock or loss of prime. Featuring a 30 ft suction lift and gentle low-shear pumping action, the A4 ProSeries pump ensures smooth and consistent operation.
With a modular roller design, tube changes can be made without tools, minimizing downtime. The A4 also supports a wide range of communication protocols, including manual control, 4-20mA input, EtherNet/IP, Modbus TCP/IP, and PROFIBUS, making it highly adaptable to advanced automated systems. Its NEMA 4X (IP66) chemically resistant enclosure ensures long-lasting durability in harsh environments.
