What Silverson does

Silverson Machines is a UK-founded (1947) and family-controlled manufacturer of high shear rotor/stator industrial mixers, operating from Waterside, UK with a US operational headquarters in East Longmeadow, MA. The company's core technology is a precision-engineered rotor/stator workhead platform with interchangeable heads (General Purpose Disintegrating Head, Square Hole High Shear Screen, Slotted Disintegrating Head, Emulsor Screens), enabling a single machine to mix, emulsify, homogenize, solubilize, suspend, disperse, and disintegrate solids. Multistage rotor/stator configurations and matched lab-to-production tolerances (e.g., 25,000 rpm laboratory speeds, self-pumping in-line capacity up to 1,100 gpm) underpin scale-up consistency from R&D to full production.

Silverson sells a comprehensive capital-equipment portfolio organized into Lab, Batch, In-Line, Powder/Liquid, Bottom Entry, and Additional Mixer series (17+ product lines), addressing food and beverage, pharmaceutical and biotech, cosmetics and personal care, chemical processing, and advanced materials including battery slurry and graphene dispersion. Revenue is generated primarily through hardware sales of high-ASP capital equipment, supplemented by genuine spare parts, on-site service by factory-trained engineers, preventive maintenance, and application-driven technical support. Pricing is quote-based and not publicly disclosed; the go-to-market is enterprise field sales delivered through direct offices in eight countries plus a network of 60+ distributors and agents globally, with free on-site trials and testing-center facilities (notably East Longmeadow MA) functioning as a critical bottom-of-funnel conversion tool.

The company is privately held with no parent, no subsidiaries, no institutional investors, and no disclosed funding events. It is the only manufacturer worldwide with mixers dual-certified to both 3-A TPV (US) and EHEDG (European) sanitary standards, a regulatory gating mechanism for pharmaceutical and ultra-sanitary food accounts. Named end-users include Pfizer, Unilever, Mondelez, Shell, IFF, and 3M alongside advanced-materials research partners such as the Graphene Engineering Innovation Centre. Ownership remains concentrated in the founding Rothman family, with Harold Rothman serving as Managing Director.

Core offering

Silverson manufactures and services high shear industrial mixing equipment based on proprietary rotor/stator workhead technology, with a product range covering laboratory to full production scale across batch, in-line, powder/liquid, bottom entry, sanitary, and ultra-sanitary configurations. The company sells directly to industrial manufacturers and supplies genuine spare parts along with on-site field service through factory-trained engineers, and supports customers with application testing, trials, and scale-up guidance.

Product overview

Silverson manufactures a comprehensive portfolio of high shear industrial mixing equipment organized into distinct product series: Laboratory Series (Laboratory Mixers, Laboratory In-Line Mixers, Laboratory Powder/Liquid Mixer) for R&D and small-scale testing; Batch Series (Batch Mixers, Pilot Scale Batch Mixers) for in-tank batch processing up to 400 gallons; In-Line Series (In-Line Mixers, High Viscosity In-Line Mixers, In-Line Ultra Sanitary Mixers, Small-Scale In-Line Mixers, Multistage In-Line Mixers) for continuous processing; Powder/Liquid Mixers (Flashmix, Flashblend) for rapid powder dispersion; Bottom Entry Mixers and Disintegrator/Dissolvers for solid incorporation; and additional mixers including Homogenizer Mixers, Ultramix Mixers, and Sanitary Mixers. The product line is unified by a common rotor/stator workhead technology with interchangeable workheads, enabling scale-up from laboratory to production. Silverson also offers a Conversion Tools mobile app for tank volume calculations and unit conversions.
