Innovations In Diaphragm Metering Pump Technology Enhance Performance

Despite their popularity in chemical metering, traditional diaphragm pumps can suffer from pulsation, vapor lock, and frequent maintenance needs. Recent innovations, however, are transforming their reliability and efficiency. Blue-White Industries’ CHEM-FEED MD1 Advanced Performance Diaphragm Metering Pump incorporates dual-diaphragm Hyper-Drive technology, enabling continuous, smooth chemical dosing by alternating suction and discharge strokes. This design virtually eliminates vapor lock and ensures consistent flow, even at extremely low turndown ratios. The pump also features a brushless DC (BLDC) motor, which provides precise control over speed and torque for steady dosing and reduced energy consumption. Additional enhancements—such as the long-life DiaFlex diaphragm, mistake-proof one-way cartridge valves, and improved sealing with a six-screw head design—extend durability and minimize downtime. Capable of pressures up to 180 psi and turndown ratios of 10,000:1, the MD1 sets a new performance standard for municipal and industrial chemical metering. With plug-and-play installation, robust construction, and simplified maintenance, it delivers long-term operational efficiency and reliability.
