CHEM-FEED® MD3 Multi-Diaphragm Metering Pump
Max Feed: .03 – 52.6 GPH (.11 – 200 LPH)
Max Pressure: 145 PSI (10 bar)
The MD3 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 eliminating the chance of vapor lock and loss of prime.
The MD3’s exclusive DiaFlex® Diaphragms will last the life of the pump, eliminating the need for expensive rebuild kits.
