Summary:Metso to acquire hose and cavity pumps business from Valmet, expanding slurry‑handling product portfolio for mining mineral processing and aftermarket service support....
Industrial hose pump and progressive cavity pump equipment for mining slurry transfer
Metso has formally agreed to acquire the hose and cavity pumps business from Valmet, a strategic equipment deal that broadens Metso’s offering for abrasive and viscous slurry handling across global mining operationsMetso. The transaction covers peristaltic hose pumps, progressive cavity pump product lines, associated spare‑parts inventory and global aftermarket service capabilities, previously marketed under the Flowrox brand. Scheduled to close in October 2026, the deal will add positive‑displacement pumping technology to complement Metso’s existing centrifugal slurry pump portfolio, helping mining customers address challenging process conditions throughout mineral processing circuitsMetso.
Mining sites regularly face difficult pumping scenarios including thickener underflow transfer, flocculant dosing, high‑solid tailings and corrosive crystallising slurries. Conventional centrifugal pumps often suffer fast wear and frequent unplanned downtime under these harsh operating conditions. Hose pumps and progressive cavity pumps deliver reliable performance for these exact demanding applications, reducing total cost of ownership through simplified maintenance and longer service cyclesValmet. By bringing this product range in‑house, Metso moves closer to delivering full‑scope slurry‑handling solutions for mine operators worldwide.

| Target End‑use Market | Mining mineral processing, heavy industrial slurry applications |
The acquired business brings an established global installed equipment base and stable recurring service revenue stream. For mine operators, the most tangible benefit will be single‑source access to both centrifugal slurry pumps and positive‑displacement pumping solutions, together with unified technical support and spare‑part supply chains. Instead of sourcing different pump types from separate vendors, plant managers can now coordinate equipment selection, maintenance contracts and component replenishment through one supplier.
Industry analysts note that this acquisition fills a clear product gap within Metso’s mineral processing equipment lineup. While Metso holds strong market position for large‑volume centrifugal slurry pumps, hose pumps and cavity pumps serve niche‑but‑critical duties where seal‑free operation and stable dosing performance are non‑negotiable. These pumps are widely used for paste backfill, chemical reagent dosing and tailings management across gold, copper, lithium and graphite processing projects.
Even after the acquisition closes, operational transition will require careful execution. Existing Valmet customers will gradually shift over to Metso’s service channels, and spare‑part availability will be a key focus point for operators running large installed pump fleets. Mine maintenance teams will monitor whether lead‑times for replacement hose elements and stator‑rotor assemblies remain consistent post‑takeover.
Looking ahead, the combined pump portfolio positions Metso to bid for more complete mineral‑processing plant packages. As global mining projects push to process more complex, abrasive ores, demand for specialised positive‑displacement pumping equipment is projected to keep rising. This deal signals that major mining equipment suppliers continue to expand their product footprint via targeted bolt‑on acquisitions rather than relying solely on in‑house product development.
For mining project developers and plant operators, the Metso‑Valmet pump acquisition represents meaningful progress toward integrated slurry‑handling solutions, potentially simplifying procurement and lowering long‑term operational risk for mineral processing facilities across all major commodity sectors.
