CD3
CHEM-FEED® Multi-Diaphragm Metering Pump
The CD3 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 CD3’s exclusive DiaFlex® and Flex-A-Prene® diaphragms for superior chemical resistance and maximum durability.
