Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers
Reviewed by Tom Sullivan

30 Second Briefing
Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
Technical Brief
- Flowrox™ hose pumps are typically selected for highly abrasive, high-solids slurries with low shear requirements.
- Progressive cavity units suit viscous, shear-sensitive or chemically aggressive process streams needing low pulsation flow.
- For brownfield concentrators, a single OEM for centrifugal and positive displacement pumps simplifies vendor qualification.
- Deal timing aligns with increased automation of slurry circuits, where accurate low-flow dosing and metering are critical.
Our Take
Metso already features heavily in our Mining coverage, with recent items on SAG mills, HRC™ crushers and long-term wear-part contracts, so adding Flowrox™ peristaltic and cavity pump technologies from Valmet further consolidates its position as a full flowsheet OEM rather than a point-solution supplier.
The acquisition strengthens Metso’s hand in brownfield debottlenecking projects like Develop Global’s Yitirrti copper-zinc-silver project in Western Australia, where integrated OEM supply of grinding, pumping and wear solutions can simplify interfaces for EPCs such as GR Engineering Services.
Given Metso’s current push to expand service centres in South America, bringing Flowrox™ mining pump IP in-house likely means more vertically integrated maintenance and spares offerings in major copper and iron ore belts, which can lock in long-term service revenue beyond the initial M&A deal.
