The dual diaphragm configuration of the CHEM-FEED MD3 allows this exceptional dosing pump to mimic the best trait of peristaltic pumps — smooth, gentle continuous flow.
When the MD3’s first diaphragm is in the suction phase, the second diaphragm is in the discharge phase. This causes gaseous fluids to be pumped through without causing vapor lock or loss of prime. MD3 is fitted with Blue-White’s exclusive, patented DiaFlex diaphragms which are designed to last the life of the pump.
