Sandvik Bringing New Levels of Flexibility, Quality and Safety to Underground Resin Injection Applications with HPA20 Pump

Why It Matters

The HPA20 raises productivity, precision and safety in underground ground‑support operations, giving miners and engineers a reliable alternative to labor‑intensive manual injection. Its data‑driven monitoring aligns with growing regulatory and quality‑control demands in the sector.

Key Takeaways

• HPA20 delivers up to 200 bar pressure.
• Supports manual and automatic two‑component resin injection.
• Self‑calibrating system ensures correct mixing ratios.
• Fully sealed 600‑litre containers eliminate operator exposure.
• Data logging integrates with QA/QC via USB export.

Pulse Analysis

Resin injection has become a cornerstone of modern ground‑support strategies, yet traditional manual methods struggle with consistency, speed, and worker safety in confined underground environments. As mines push deeper and civil projects demand tighter tolerances, automation offers a path to higher throughput and reduced human error. The HPA20 arrives at this inflection point, marrying hydraulic power with smart controls to deliver precise pressure and flow rates while maintaining the flexibility to operate as a standalone unit or integrate with existing drill rigs.

At the heart of the HPA20 is a self‑calibrating control system that continuously monitors mixing ratios, pressure, flow, and volume, guaranteeing optimal resin performance. Its ability to handle up to 200 bar and 10 L/min per component ensures robust injection for both silicate and polyurethane formulations. The sealed dual‑container design, each holding 300 litres, removes operator exposure during filling and injection, while automatic flushing prevents blockages. Comprehensive data capture—exportable via USB—feeds directly into quality‑assurance workflows, supporting the documentation standards increasingly required by regulators and project owners.

For mining and civil‑engineering firms, the HPA20 represents more than a new piece of equipment; it signals a shift toward data‑centric, safer ground‑support operations. By reducing manual labor, cutting cycle times, and providing traceable performance metrics, the pump can improve overall project economics and compliance. As the industry embraces digitalization, solutions like Sandvik’s HPA20 are likely to set new benchmarks for efficiency, safety, and reliability in underground construction and resource extraction.
