Blue-White’s Proseries-M® MD-3 Diaphragm Metering Pump has 2000:1 turndown, and provides smooth chemical dosing with no pulsation dampener required. With 380 strokes per minute, the metering pump provides a remarkably steady flow. The MD-3 is built to provide long service life at high pressures and no pressure regulator is needed. A single model includes all necessary components for installation, and the drop-in-place design of the MD-3, along with conveniently built-in controls, make installation and set-up fast and efficient. The PVDF wetted end fittings allow for more than 14 inlet and outlet configurations.
