The CHEM-FEED® C2 & C3 – Diaphragm Metering Pump
Description
Meet the Updated C2 & C3 CHEM-FEED® Diaphragm Metering Pumps
The C2 and C3 CHEM-FEED® Diaphragm Metering Pumps have been trusted in chemical feed applications for years — delivering accurate, quiet performance in demanding treatment environments.
Now, they’re even better, with expanded control options and new NSF 61 certification for potable water and regulated applications.
C2 & C3 Performance
Both pumps are designed for accurate chemical feed, even in high-pressure applications, and feature:
- NEMA 4X, IP66 enclosure
- Backlit LCD interface
- Patented DiaFlex® diaphragm designed to last the life of the pump
- 100:1 turndown ratio
- NSF 61 certification
C2 Performance
The C2 is built for applications requiring higher pressure and precise low-to-mid flow rates.
The C2 delivers:
- Flow Rate: Up to 16.5 Gallons Per Hour (GPH)
- Pressure: Up to 175 PSI
- Turndown Ratio: 100:1
The C2 also includes Diaphragm Failure Detection, which continuously monitors the pump head and triggers an alarm if a diaphragm rupture is detected — helping prevent unexpected downtime.
The C2V model now includes 4–20 mA output, making it easier to integrate into automated and SCADA-controlled systems.
C3 Performance
The C3 builds on the same platform but is designed for higher-flow chemical feed applications.
The C3 delivers:
- Flow Rate: Up to 40 Gallons Per Hour (GPH)
- Pressure: Up to 150 PSI
- Turndown Ratio: 100:1
Like the C2, the C3 features DiaFlex diaphragms, DFD leak detection, and operator-friendly digital controls — with additional output capability, including 4–20 mA output, relay, and open collector signals.
Built for Modern Chemical Feed Systems
Both the C2 and C3 support:
- Manual control
- Remote start/stop
- Pulse input
- 4–20 mA analog control
- Compatibility with Blue-White’s Flow Verification Sensor
Flow verification adds another layer of confidence by helping confirm that chemical is actually being delivered.
