Precision chemical feed just got easier.

Brushless motor-driven. Fast prime. 150 PSI. The new MD1 CHEM-FEED Multi-Diaphragm Pump from Blue-White is the one-pump solution for municipal water & wastewater treatment. Its broad feed range allow standardization on one pump, simplifying your operations.

Perfect priming – even with hypo.

No more leaking chlorine pumps. With dual diaphragm hyperlink drive technology, the MD1 will not lose prime – even when pumping chemicals that off-gas, like peracetic acid and sodium hypochlorite.

Smooth chemical feed

The MD1 mimics the best traits of peristaltic pumps – smooth, gentle, continuous flow – with the first diaphragm is in the suction phase and the second in the discharge phase.

Unlike a peristaltic pump, the MD1 does not rely on a tube assembly that will wear out and need replacement. The patented DiaFlex diaphragms are designed to last for the entire life of the pump.

We are proud to partner with Blue-White to provide our customers with quality solutions for a wide variety of water and wastewater treatment applications. I’m confident that together, we’ll be able to help our customers in their mission of providing safe, clean, high-quality water to every home and business in their service area.
