Cemented Paste Backfill (CPB) and high-density slurry transport systems are essential to modern underground mining—but they also bring a serious operational challenge: pipeline blockages caused by settled solids, thickened slurry, or premature setting of paste. Once blocked, paste lines are notoriously difficult (and costly) to clean, often requiring mechanical removal, line replacement, or even re-drilling.
The Aranzu High Pressure Flush Valve is purpose-built to prevent these issues by delivering high-energy flushing at critical points in your pipeline network—whether you’re moving tailings, slurry, or paste backfill. It’s a proactive, rugged solution designed for the realities of remote, high-pressure mining environments.
Why does your backfill or slurry system need a flush valve?
CPB and slurry pipelines operate close to the limit—narrow velocity ranges, high solids content, and long horizontal runs. If material slows or sits, it starts to settle. In CPB, it can even start to set in the line, causing irreversible blockages. Our High Pressure Flush Valve gives operators a fast, reliable way to flush out these problem areas before they escalate—keeping production moving and reducing the risk of pipeline loss.
What the Aranzu Flush Valve delivers to your operation:
- Blockage prevention in paste and slurry lines: Timely flushing stops solids from settling or paste from setting, which is especially critical in horizontal sections or low-flow conditions.
- Minimised downtime in CPB systems: Once paste lines are blocked, recovery is complex. Our valve helps you stay ahead of the issue—avoiding emergency interventions and lost production.
- Extended equipment and pipeline life: Flushing removes abrasive and erosive buildup before it eats into your infrastructure—preserving pumps, pipes, and valves.
- Automated or manual activation for safer operation: Flush cycles can be triggered remotely or on schedule, reducing the need for hands-on maintenance in high-risk areas.
- Process stability and efficiency: Keeping lines clean ensures consistent paste flow, reduces energy use, and improves backfill placement accuracy.
- Retrofit-ready for brownfield sites: Compact and robust, the valve is designed for easy integration into existing infrastructure, whether above or underground.
In summary, the Aranzu High Pressure Flush Valve is more than a maintenance tool—it’s an operational safeguard. For mines using CPB, it protects your most vulnerable assets: the paste lines. For high-density slurry systems, it maintains consistent flow and protects against downtime. In both cases, it gives your operation the control and reliability it needs to run smoothly, day in and day out.
