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

### Q: What materials are best for pump housings in molten metal applications?
**A**: High-temperature cast iron, heat-resistant steel alloys, and ceramic-lined steel are optimal for withstanding extreme temperatures and corrosive environments in molten metal pumping.

### Q: Why is a cooling jacket important in pump housing design?
**A**: A cooling jacket helps regulate temperature, preventing overheating and extending the lifespan of both the housing and internal pump components during continuous molten metal transfer.

### Q: How does inspection port design affect pump maintenance?
**A**: Properly positioned inspection ports allow for visual monitoring and maintenance access without disassembling the entire pump, reducing downtime in basic metal manufacturing operations.

## 6. Manufacturing Compliance
- ISO 5199:2002 (TECHNICAL SPECIFICATIONS FOR CENTRIFUGAL PUMPS)
