Blue-White’s exclusive hyperdrive technology ensures the multi-diaphragm CHEM-FEED MD3 will deliver smooth, precise and dependable chemical feed with no vapor lock and no lost prime. With MD3, when the first diaphragm is in the suction phase, the second diaphragm is in the discharge phase of the cycle. This results in near-continuous feed and gaseous fluids being constantly pumped through the head and out. Choose MD3 for smooth, quiet and consistent chemical dosing.
