30 Second Briefing
Weir has secured a multimillion‑dollar contract with a major Chinese non‑ferrous metals company to supply WARMAN® pumps for the Phase III expansion of a Xizang copper mine. The package comprises two WARMAN MCR® 450 cyclone feed pumps and nine WARMAN AHPP 20/18 tailings transfer pumps serving the grinding circuit and tailings system. For engineers, the deal signals continued preference for high‑capacity slurry and tailings pumping solutions in large‑scale Chinese copper concentrator expansions.
Technical Brief
- Package combines cyclone feed and tailings transfer duties within a single coordinated pump supply.
- MCR® 450 units are configured as cyclone feed pumps, indicating high-throughput grinding and classification circuits.
- AHPP 20/18 pumps are assigned to tailings transfer, pointing to a dedicated high-head disposal line.
- Centralised sourcing of 11 large slurry pumps simplifies spares, wear‑part inventory and maintenance planning.
Our Take
Recent coverage of Weir’s Q1 2026 results highlighted a growing pipeline of large equipment projects for mine debottlenecking and brownfield expansion; securing multimillion‑dollar WARMAN pump work at a copper site like Xizang suggests that copper remains one of the more active drivers of that order book.
The simultaneous expansion of Weir’s Heavy Bay Foundry and its new 14,500 sq.m Perth facility in Hazelmere indicates that the company is building manufacturing and service capacity to support exactly these kinds of large WARMAN MCR and AHPP pump packages for high‑throughput copper circuits.
