ProSeries-M MD-3 chemical metering/dosing pump features dual pump heads that deliver precise chemical dosing to water and wastewater treatment systems.

Pumps with a single diaphragm have a pumping cycle that consists of a suction and discharge phase. The resulting intermittent pumping of chemicals, specifically during the suction phase of the cycle, can cause gas buildup, which in turn causes vapor lock and loss of prime.  

This is where the dual-head configuration of the ProSeries-M MD-3 delivers superior performance: it will not lose prime. When the MD-3’s first diaphragm is in the suction phase, the second diaphragm is in the discharge phase. This causes gaseous fluids to be pumped in a near continuous flow.

The hybrid MD-3 diaphragm/metering pump has an excellent turndown ratio of 2,000-to-1 and provides smooth chemical dosing with no pulsation dampener required. With 380 strokes per minute, the ProSeries-M MD-3 provides a remarkably steady flow.

MD-3 is engineered and built to provide long service life even at high pressures, and no pressure regulator is required. The pump design is also 50 percent more energy efficient than similar units currently available. 

The thoughtfully designed and engineered MD-3 is equipped with sonic welded manifolds to prevent chemical leaks and features a zero-maintenance brushless DC drive.

Ordering is straightforward and all-inclusive: A single model includes all necessary components for installation. The drop-in-place design of ProSeries-M MD-3, along with conveniently built-in controls, make installation and setup fast and efficient.
