Sandvik HPA20 resin injection pump: bolt installation control for ground engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Sandvik has introduced the HPA20 automatic resin injection pump for resin-based ground support, designed to automate resin mixing and delivery in underground bolting operations. The system integrates with Sandvik bolters to control resin volume and injection pressure, reducing manual handling at the face and improving consistency in encapsulation around rock bolts. For geotechnical and ground support engineers, this points to tighter control of bolt installation parameters and potential reductions in variability of resin annulus quality in highly stressed ground.
Technical Brief
- Similar automated injection systems could support compliance with site‑specific ground control management plans and regulator audit trails.
Our Take
Sandvik has had a dense run of product launches in March 2026 – from the HPA20 resin system to the MC431 continuous miner and Ranger DX1010i drill – signalling a push to refresh its hard‑rock portfolio that Australian underground operators will likely see as an integrated package rather than isolated tools.
Within our 796 safety‑tagged mining pieces, relatively few focus on ground support hardware compared with mobile equipment incidents, so this automatic resin injection pump points to a quieter but important risk‑reduction front in strata control rather than vehicle or procedural safety.
The absence of commodity‑specific angles in recent Sandvik coverage (e.g. the CH442/CH662 cone crushers and South African exciter refurbishment facility) suggests the company is positioning these launches, including this pump in Australia, as fleet‑agnostic productivity and safety upgrades that can be justified across multiple ore types and mine plans.
