CHEM-FEED® Multi-Diaphragm Metering Pump
The MD1 Multi-Diaphragm Metering Pump delivers smooth, continuous chemical feed even when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite. The cutting-edge Hyperdrive Technology allows for alternating pumping action between two diaphragms: when one diaphragm is in the suction phase, the other is in the discharge, resulting in a smooth chemical feed profile and minimizing the risk of vapor lock.
The MD1’s exclusive DiaFlex® Diaphragms will last the life of the pump, eliminating the need for expensive rebuild kits.
