Stamo Maskin

What Stamo Maskin does

Stamo Maskin, operating commercially as STAMO Agitation Solutions, is a Swedish designer and manufacturer of customized industrial agitators and mixers, founded in 1949 and headquartered in a single facility in Västerås, Sweden. The company engineers bespoke agitation systems spanning power outputs from 0.09 kW to 300 kW, shaft lengths up to 40 meters, and impeller diameters from Ø75 to Ø8000 mm, supported by 15+ impeller types, multiple shaft-sealing options, and a broad material portfolio including stainless steel, duplex, titanium, Hastelloy, and various linings. Engineering is anchored by the proprietary Flow Calculate sizing tool and in-house CFD and FEM simulation capabilities, with manufacturing performed on CNC lathes and waterjet systems. ATEX-certified variants address explosive-atmosphere applications.

The company sells exclusively to enterprise customers across eight process-industry verticals: biogas, water & sewage, pharmaceuticals, chemicals, paper & pulp, mining, food & dairy, and flue gas treatment. Notable reference customers include Northvolt (battery-recycling acid mixing), Cepheid (SARS-CoV-2 test reagent mixing), Borås Energi och Miljö (3,400 m³ digester), and three Turkey biogas projects with tank volumes of 7,000–9,500 m³. Go-to-market is direct enterprise field sales organized by geography — Sweden, Germany, Belgium/UK, and International — with no third-party channel partners; pricing is quote-based and customized per application. Multi-language brochures (English, German, French, Spanish), recurring IFAT exhibition presence, and active LinkedIn/Facebook/YouTube channels support demand generation.

Ownership is private. In August 2025, J2L Holding AB — a family-owned industrial-sector investor — acquired 70% of parent entity Stamo Förvaltning AB, with founder-co-owner Johan Rosendal transitioning from CEO to CSO/Sr. Technical Sales and Per Andersson appointed as the new CEO in March 2026. The company holds ISO 9001, ISO 14001, ISO 45001, and ATEX Directive 2014/34/EU certifications. Revenue is not publicly disclosed; with 11–50 employees operating from a single facility, the business is a focused niche industrial manufacturer rather than a high-volume equipment vendor.

Emerging players

• Mixer Direct: US online retailer and manufacturer of industrial mixers and agitators offering more standardized, lower-power products; serves as an emerging player that competes with Stamo at the lower end (standard 0.09-4 kW range) and in replacement/smaller-tank applications.
• Statiflo International: UK-based specialist in static mixers and process equipment for water, chemical, and industrial applications; relevant adjacent peer since it competes for mixing-technology specification in overlapping verticals like water treatment and chemicals.

Direct peers

• Philadelphia Mixing Solutions: US-based manufacturer of industrial mixers and agitators offering engineered solutions for chemical, water, and mining applications; comparable in its custom engineering focus and CFD-driven design approach, making it a relevant cross-Atlantic direct peer.
• Hayward Gordon: North American manufacturer of industrial mixers and agitators for mining, chemical, water, and process industries; comparable mid-sized custom-engineering manufacturer with similar application-specific positioning to Stamo.
• Ekato Group: German-based manufacturer of industrial agitators and mixers with a comparable focus on customized process equipment using CFD/FEM engineering; serves the same chemicals, pharma, water, and biogas verticals, making it Stamo's closest direct competitor especially in the German-speaking and European markets.

Broad incumbents

• Xylem (Flygt/Mixer Products): Global water technology company with significant industrial mixing, aeration, and agitator offerings through brands like Flygt and Wedeco; competes with Stamo particularly in water and sewage treatment and biogas digester mixing applications.
• Sulzer: Swiss industrial conglomerate whose Mixing Technology division supplies agitators, mixers, and aerators for water/wastewater, chemicals, and biogas; offers broader product lines and global service, positioning it as a large incumbent competitor across most of Stamo's served verticals.
• Chemineer (Graham Corporation): Graham Corporation's Chemineer brand is a long-established US manufacturer of industrial agitators and mixers for chemical, water, and pharmaceutical applications; a broader incumbent with deeper global service infrastructure than Stamo but overlapping technology base.
• SPX FLOW (Lightnin): Global industrial equipment maker whose Lightnin brand is one of the most recognized industrial agitator/mixer lines worldwide; serves chemicals, water treatment, pharma, and mining with both standard and engineered units, directly overlapping Stamo's customization-heavy offering.

Regional players

• Proserve (Pioneer Pump / agitator brands): European regional industrial pump and mixing equipment supplier that overlaps with Stamo in European water/sewage and biogas applications but primarily serves the DACH region, making it a comparable regional peer.
