Flowrox

What Flowrox does

Flowrox is a Finland-based brand specializing in valves and pumps engineered for demanding industrial process conditions involving abrasive, corrosive, and high-solids media. Originally founded as Larox in 1977, the business was separated as Larox Flowsys, renamed to Flowrox in 2011, acquired by Neles in 2021, and integrated into Valmet's Flow Control business line on April 1, 2022. The company is headquartered in Lappeenranta, Finland, with 51-100 employees, and operates as a brand within Valmet (Nasdaq Helsinki: VALMT), a publicly listed strategic parent.

The core product portfolio centers on elastomer-based flow control technology: heavy-duty pinch valves (PV, PVE, PVE/S, PVG, PVEG series), slurry knife gate valves with one-piece cast bodies, peristaltic pumps (LPP-T transfer pumps with single-roller design and LPP-D dosing pumps), Expulse pulsation dampeners rated to absorb up to 90% of pulsation, and progressive cavity pumps in E-, EL-, and D-series variants. The proprietary elastomer sleeve is positioned as the only wear-resistant component in contact with the process medium, minimizing maintenance and spare part consumption in slurry service. Differentiators include a simplified two-service-part knife gate valve design, bidirectional flow tolerance, full-bore open-position flow, and energy-efficient single-roller pumping.

Commercially, Flowrox sells through Valmet's global Flow Control sales and service network augmented by regional channel partners such as Anasia in the GCC, targeting enterprise customers in mining, minerals processing, metallurgy, pulp and paper, energy, construction, water and wastewater, chemical, food and beverage (sugar processing), and marine and offshore. Revenue mechanics combine one-time capital equipment sales, OEM spare parts (hoses, tubes, stators, rotors, elastomer sleeves) including compatible parts for other brands, and professional valve maintenance and repair services. Pricing is quote-based B2B industrial and not publicly disclosed. Certifications include ISO 9001:2015 (quality) and ISO 14001:2015 (environment) multisite certificates.

Brands

• Flowrox™ pinch valves: Heavy duty pinch valves designed for shut off and control applications involving abrasive or corrosive slurries, powders or granular substances.
• Flowrox™ slurry knife gate valves
• Flowrox™ LPP-T peristaltic pumps
• Flowrox™ LPP-D dosing pumps
• Flowrox™ Expulse™ pulsation dampener
• Flowrox™ progressive cavity pumps

Products and services

• Pinch Valves Pinch valves use a flexible elastomer sleeve as the only wetted part, providing leak-tight shutoff and resistance to abrasive slurries, corrosive chemicals, and dry powders. Designed for industrial process operators in mining, minerals processing, pulp and paper, chemical, water and wastewater, and similar heavy industries.
• Slurry Knife Gate Valves Slurry knife gate valves are designed to handle slurries, pulp stock, and dry powders in demanding isolation and on/off service. Targeted at mineral processing, pulp and paper, and other heavy process industries requiring rugged shutoff valves.
• Peristaltic Pumps Peristaltic pumps move abrasive, corrosive, or high-solids fluids through a flexible hose squeezed by a roller, isolating the pumped media from the pump mechanism. Used by heavy industrial operators handling slurries, chemicals, and other aggressive media.
• Progressive Cavity Pumps Progressive cavity pumps handle viscous, shear-sensitive, and solids-laden fluids at consistent flow rates. Suited for chemical, wastewater, food and beverage (including sugar), and other heavy process applications.
• Pulsation Dampeners Pulsation dampeners smooth pressure and flow variations in pumping circuits, protecting piping, instrumentation, and downstream equipment. Used by industrial operators deploying peristaltic and progressive cavity pumps in demanding process service.

Quantifiable outcome

• Absorbs up to 90% of pulsations in pump applications
