MD3 CHEM-FEED® Multi-Diaphragm Metering Pump

The MD3 CHEM-FEED® is a multi-diaphragm metering pump engineered for precise, reliable chemical dosing in municipal and industrial water treatment systems. Its multiplexed diaphragm design delivers smooth, low-pulsation output while minimizing vapor lock and loss of prime — common failure points in single-diaphragm pumps. Built with Blue-White's DiaFlex® diaphragm technology, the MD3 resists chemical degradation and extends service life even in demanding dosing applications. Hyperdrive Technology provides high turndown and accurate flow control across a wide range of feed rates, giving operators confidence in consistent, repeatable dosing. A NEMA 4X-rated enclosure protects internal components in wet or corrosive environments, while 4-20 mA input supports seamless integration into SCADA and automated control systems. Whether dosing disinfectants, coagulants, or pH adjustment chemicals, the MD3 is built to perform reliably in continuous-duty water and wastewater operations.
