Sandvik HPA20 resin pump: control, bond quality and safety insights for engineers

30 Second Briefing
Sandvik has launched the HPA20 (Hydraulic Power Automatic) injection pump as a next-generation system for resin-based ground support in hard-rock mining and civil works, combining intelligent automation with a modular, flexible architecture for underground use. The unit automates resin dosing and injection cycles, aiming to improve bond quality and consistency in rockbolts and cable bolts while reducing operator exposure at the face. For geotechnical and ground support teams, the key change is tighter control of resin volumes and timing, supporting more predictable load transfer and ground behaviour.
Technical Brief
- For other underground projects, similar automated dosing and remote operation could help standardise resin QA/QC procedures.
Our Take
Sandvik’s HPA20 launch sits alongside a cluster of recent Sandvik equipment roll-outs in our database – from the MC431 continuous miner to Ranger DX1010i drill rigs – signalling a push to offer more integrated, OEM‑supplied solutions across both development and support functions underground.
Within the 2,071 tag‑matched pieces on Projects/Product/Safety, Sandvik appears frequently as an equipment supplier, which suggests that mines adopting the HPA20 resin injection pump are likely to find it easier to standardise maintenance, training and spares with other Sandvik fleets already on site.
For underground operators, pairing a dedicated resin injection system like the HPA20 with Sandvik’s newer continuous miners (such as the MC431 referenced in our coverage) could enable tighter control of ground support cycles, reducing exposure time at the face and making it easier to document compliance with ground control management plans.
