Mamec

What Mamec does

Mamec Oy is a Finnish industrial mixing technology specialist founded in 1951 and headquartered in Lohja, Finland. The company designs, manufactures, and markets industrial agitators and special pumps for demanding process applications across primary verticals of pulp and paper, renewable energy/biogas, and water treatment, with additional exposure to marine, mining, battery chemicals, and other process industries. Core products span four agitator categories (side entry, container, top entry, and special agitators) with power ranging from 0.18 kW to over 300 kW and tank lengths up to 30 meters, supported by CFD flow modeling and in-house rheology expertise; the pump portfolio covers slurry, vortex, cantilever, wastewater, flood, and marine pumping stations, all custom-configured for specific process conditions.

The business model is engineering-led and project-based: all solutions are tailored to customer-specific requirements via a quote-based pricing model with no published standard tiers, requiring close technical collaboration between Mamec's engineers and customer process teams. Revenue is generated primarily through hardware sales of mixing equipment and pumps, complemented by lifecycle maintenance, spare parts, and inspection services, plus a growing contract manufacturing line producing precision mechanical and automation assemblies for semiconductor, pharmaceutical, and medical customers through the Precision Mechanics division. Mamec distributes via direct enterprise sales, industry trade shows (SPaper, YT25, MIAC), and a website-based request-for-quotation funnel, with international presence in biogas solutions dating to 1995.

The company operates as a subsidiary of the Finnish Kaarjoki Group, holds ISO 9001:2015 and ISO 14001 certifications, employs 51-100 people across its headquarters and production facility in Lohja, and serves marquee customers including Tui Cruises, Carnival, Royal Caribbean, Costa, Viking Line, Tallink, and Color Line in the marine segment. A controlled leadership transition is underway, with Antti Jokiranta (formerly of Xylem) succeeding longtime Business Director Martti Heikkilä at the turn of 2026.
