CHEM-FEED CD3 Multi-Diaphragm Metering Pump

Continuous Flow for Reliable Chemical Feed

Max Feed: 0.05 – 52.6 GPH (0.19 – 199 LPH)

Max Pressure: 145 PSI (10 bar)

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® Diaphragms last the life of the pump, ensuring virtually maintenance-free chemical feed.

• No loss of prime with gaseous chemicals like Peracetic Acid (PAA) or Sodium Hypochlorite
