CHEM-FEED® C3 Diaphragm Metering Pump

The CHEM-FEED® C3 delivers accurate, quiet chemical feed against high system pressures for industrial dosing applications. An easy-to-read backlit LCD interface with optional 4-20 mA, pulse, and frequency input gives operators the power and flexibility to take control of their fluid management process. Exclusive DiaFlex® diaphragms are designed to last the life of the pump, eliminating the need for expensive rebuild kits. Feed rates range from .3–40 GPH (1.1–154 LPH) at pressures up to 150 PSI (10.3 Bar), with a 100:1 turndown ratio for accurate metering. Signal inputs include 4-20 mA, pulse, and remote start/stop, with signal outputs supporting relay, open collector, and 4-20 mA — all compatible with Blue-White's Flow Verification Sensor (FVS) system for SCADA-ready integration. Patented Diaphragm Failure Detection (DFD) senses diaphragm rupture without false triggering, and a NEMA 4X, chemically resistant powder-coated enclosure supports reliable operation in harsh environments. Backed by a 2-year warranty.
