Metso has signed an agreement to acquire Valmet’s peristaltic hose pump and progressive cavity pump technologies, along with related spare-parts and service capabilities. The move is set to broaden Metso’s slurry-handling offering for mining and industrial customers worldwide.
The transaction is expected to close on October 1, 2026, subject to customary conditions. The companies have not disclosed the value of the deal, which Metso says is not expected to have a material effect on its financial performance.
The acquired products currently operate under the Flowrox brand. Once the deal is completed, they will be folded into Metso’s pump portfolio and rebranded under the Metso name, aligning them with the company’s broader equipment and service offering.
Broadening slurry-handling capability
The acquisition adds hose-pump and progressive-cavity-pump technologies to Metso’s existing slurry-handling range, which already includes slurry pumps, pipes, hoses, valves and hydrocyclones, as well as maintenance, optimisation and spare-parts services. Together, these form an increasingly complete toolkit for operators managing demanding slurry streams across the mineral-processing chain.
Peristaltic hose pumps are built for difficult duties involving abrasive, corrosive, viscous or crystallising slurries—conditions that quickly wear down conventional pumping equipment. In mining operations, potential applications include thickener underflow, filter feed, flocculant dosing, slurry sampling and recirculation. These are areas where continuous flow, long wear life and straightforward maintenance matter most, particularly in operations running around the clock with limited tolerance for unplanned downtime.
For mining operators across Africa, the expanded range could give Metso a more complete equipment and lifecycle-service proposition for handling challenging mineral-processing slurries. This spans the full processing sequence, from plant feed and thickening through to tailings-related duties, giving operators a single technology and service partner across multiple stages of the flowsheet rather than relying on a patchwork of suppliers.
Production to move to Finland
Production of the acquired products will be transferred to Metso’s manufacturing site in Lappeenranta, Finland, with relevant personnel also relocating to the facility. This consolidation is intended to integrate the technologies more closely into Metso’s existing manufacturing and engineering operations.
Metso said the acquisition also brings an established installed base and recurring aftermarket opportunities, strengthening its ability to provide long-term parts and service support in key mining markets. For operators, this points toward improved access to spares and technical support over the equipment’s operating life, an important consideration in regions where logistics and lead times can affect plant uptime.
Tiago Marques Oliveira, Vice President of Metso’s Pumps Business Line, said the deal would complement the company’s heavy-duty pumping range and reinforce its position as a full-lifecycle slurry-handling partner—covering equipment selection, installation, and ongoing service and optimisation support.
Metso, headquartered in Espoo, Finland, reported approximately 18,000 employees in around 50 countries and sales of about EUR 5.3 billion in 2025.
