Metso Adds Flowrox Pump Technology as Valmet Narrows Its Focus

Metso is expanding its pumping capabilities in mining with an agreement to acquire Valmet’s Flowrox pump business, adding peristaltic hose pumps and progressive cavity pumps to its existing portfolio. The transaction covers the pump technologies, associated spare parts and aftermarket services. The Flowrox trademark will remain with Valmet, as will Flowrox valves, which continue to form part of Valmet’s flow-control offering. The deal is expected to close on October 1, 2026; financial terms have not been disclosed.

For Metso, the deal fills a specific gap: more pump technologies for difficult mining applications, backed by an existing aftermarket business. Flowrox’s peristaltic hose pumps are designed for applications involving abrasive slurries and demanding solids handling, while progressive cavity pumps are used for viscous, abrasive and corrosive media. Those capabilities complement Metso’s existing slurry-pump portfolio and strengthen its position across mineral-processing operations.

Metso has been building a broader minerals-processing proposition spanning equipment, process solutions and lifecycle services. Adding these pump technologies allows the company to address more pumping requirements within a plant and deepen its aftermarket presence.

Valmet, meanwhile, is moving in the opposite direction. The company says the divestment will allow it to concentrate resources on mission-critical valves and valve automation, while sharpening its focus on mining and metals within its Flow Control business.

The move is consistent with Valmet’s wider portfolio reshaping. In 2025, the company also agreed to divest its FXM metering pump technology, another Flowrox-origin product, to Lutz-Jesco. The pump transaction therefore looks less like an isolated asset sale and more like continued pruning of Valmet’s Flow Control portfolio.

The transaction also illustrates how industrial companies are reshaping portfolios around where their existing technology, customers and service networks overlap most effectively.

The outcome is therefore straightforward: Metso gets deeper into mining pumps; Valmet gets more focused on valves and automation. The strategic value lies less in the pump models themselves than in how neatly each side’s portfolio becomes aligned with its next phase of growth.
