- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in this metering pump/valve and why?
**A**: This component uses 316L stainless steel for corrosion resistance, PTFE for chemical inertness and low friction, and ceramic for wear resistance and dimensional stability in precision resin dispensing applications.

### Q: How does this metering pump/valve ensure accurate resin volume control?
**A**: The precision diaphragm/piston mechanism combined with inlet/outlet check valves and optimized pump head/chamber design provides consistent, repeatable resin dispensing with minimal variation for manufacturing consistency.

### Q: What maintenance is required for this metering component in industrial use?
**A**: Regular inspection of the diaphragm/piston and check valves is recommended, with periodic cleaning to prevent resin buildup. The stainless steel and ceramic construction minimizes corrosion and wear for extended service life.

## 6. Manufacturing Compliance
- ISO 28580:2011 (PUMPS - ACCEPTANCE TESTS FOR METERING PUMPS)
