Sandvik Launches Automated Resin Injection Pump for Underground Use
Hydraulic system enables controlled silicate and polyurethane injection with automated monitoring, improving safety, process consistency, and QA/QC documentation in ground support operations. www.home.sandvik Hard-rock mining, tunneling, and civil engineering projects rely on resin injection systems to stabilize rock formations, secure anchors, and ensure long-term structural integrity. In these environments, precise control of injection parameters and operator safety are critical. Sandvik has introduced the HPA20 automatic injection pump to address these requirements, combining automation with flexible deployment for underground operations. Automated and manual resin injection in one system The HPA20 (Hydraulic Power Automatic) supports both manual-controlled and fully automated injection of two-component silicate and polyurethane resins. This dual-mode capability allows operators to adapt injection processes depending on site conditions, complexity, and operator preference. The system can function as a standalone unit or integrate with underground equipment such as drill rigs. It can be powered by onboard hydraulics or an optional auxiliary hydraulic power pack, making it suitable for operations where existing equipment cannot support bulk resin systems. Typical applications include: Rock bolting and anchoring Ground consolidation in fractured zones Stabilization in tunneling and excavation projects Precise control of pressure, flow, and mixing ratios At the core of the system is a self-calibrating control unit that continuously regulates mixing ratios and injection parameters. This ensures consistent resin quality and reduces variability in ground support performance. The pump delivers: Up to 200 bar injection pressure Up to 10 L/min per component By maintaining stable pressure, flow, and volume, the system supports uniform resin distribution, which is essential for reliable anchoring and void filling in underground environments. Data logging supports QA/QC workflows In automatic mode, the HPA20 records detailed data from each injection cycle, including mixing ratios, pressures, flow rates, and injected volumes. These datasets can be exported via USB and integrated into quality assurance and quality control (QA/QC) processes. This capability enables: Traceability of injection operations Verification of compliance with engineering specifications Improved documentation for safety and regulatory requirements Such data-driven approaches are increasingly required in modern mining and infrastructure projects. Safety-focused design for underground operations Operator safety is a central aspect of the system design. The HPA20 incorporates a sealed dual-container system (2 × 300 liters), reducing operator exposure to chemical resins during handling and injection. Additional safety features include: Automatic and manual flushing to prevent blockages Reduced risk of operator error through controlled workflows Separate access levels for operators and supervisors These measures contribute to safer handling of reactive resin materials in confined underground environments. Compact design with flexible deployment options With dimensions of approximately 2.8 × 1.4 × 1.6 meters and a weight of 1,275 kg, the unit is designed for transport and positioning in underground spaces. Multiple lifting and transport configurations support deployment across different site conditions. The system operates within a temperature range of 10°C to 45°C, covering typical underground environments. For applications requiring additional hydraulic capacity, an optional power pack with a 22 kW motor and 60-liter tank is available. Positioning in automated ground support systems Automated resin injection systems are increasingly replacing manual methods to improve consistency, safety, and documentation. Compared to manual injection setups, automated systems such as the HPA20 enable tighter control over process parameters and reduce variability between operators. Sandvik’s solution combines automation, data logging, and flexible integration, aligning with industry trends toward digitalized and standardized ground support processes in mining and civil engineering.
