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

### Q: What materials make this high-pressure pump suitable for metal descaling?
**A**: Constructed with high-strength alloy steel and hardened steel components for durability, bronze bushings for reduced friction, and Viton/polyurethane seals to withstand high-pressure hydraulic fluids in demanding metal processing environments.

### Q: How does this pump unit handle pressure control during descaling operations?
**A**: The unit includes a precision pressure relief valve that automatically regulates hydraulic pressure to prevent system overload, ensuring consistent descaling performance while protecting pump components from damage.

### Q: What maintenance is required for the piston and cylinder assembly?
**A**: Regular inspection of pistons, cylinders, and valve plates is recommended, with lubrication of bronze bushings and seal replacement as needed. The robust alloy steel construction minimizes wear, but following manufacturer service intervals optimizes longevity.
