What Probst & Class does

Probst & Class GmbH & Co. KG, operating under the "PUC" brand, is a German industrial machinery manufacturer founded in 1926 and headquartered in Rastatt, Baden-Württemberg. The company designs and builds capital equipment for wet milling, emulsifying, dispersing, homogenizing, de-aeration, dissolving, mixing, and pre-comminution processes, organized into three core machine families: PUC colloid mills (Types O, E, EL) with capacities up to 80,000 l/h; PUC multistage mixers branded as Vibroreactors (Types O, E, EL) up to 50,000 l/h; and PUC perforated disc mills (Types O, E, EL) for pre-comminution and wet milling of solids in liquid. These are complemented by vacuum de-aeration units (EVA) handling up to 10,000 kg/h, lubricant processing units for greases up to 10,000 kg/h, and a customised machinery service for application-specific configurations. The company also operates an Engineering Centre for scale-up from laboratory to production, a pucLab machine lending ("try before you buy") program, and an after-sales service arm.

Probst & Class sells to industrial customers across five primary verticals — pharmaceutical, food & beverage, chemical, petrochemical, and cosmetics — with end products spanning suspensions, ointments, creams, juices, peanut butter, ketchup, dairy products, adhesives, coatings, pigments, bitumen emulsions, lubricants, and personal care items. The go-to-market is sales-led and direct, combining an international sales team based in Germany with a global distributor network organized by world region, and an exclusive European reseller arrangement for complementary Mountech products. Pricing is quote-based and not publicly disclosed, with contracts typically structured as multi-year agreements. Marketing is conducted through a multi-language website (German, English, Spanish), industry-specific landing pages for each vertical, and a machine request form that matches customer processing needs to equipment.

The firm is a privately held German limited partnership (GmbH & Co. KG) with no disclosed parent company, institutional investors, or external ownership. Headcount is reported at 5 employees, implying a highly leveraged organization reliant on accumulated engineering expertise, channel partners, and a century-long installed-base reputation. No revenue figures, funding events, or external capital are disclosed.

Core offering

Probst & Class designs, manufactures, and sells industrial processing machinery for wet milling, emulsifying, dispersing, homogenizing, de-aeration, and mixing of liquids, suspensions, emulsions, and pasty products. Its portfolio spans colloid mills, multistage mixers (Vibroreactors), perforated disc mills, vacuum de-aeration units, lubricant processing units, and customized machinery, complemented by engineering services, machine lending (pucLab), and after-sales support.

Product overview

Probst & Class (PUC) is a German industrial machinery manufacturer specializing in processing equipment. The product portfolio consists of three core machine types—Colloid Mills, Multistage Mixers (Vibroreactors), and Perforated Disc Mills—each available in three orientations (Type O, E, EL) with varying motor configurations and capacities. These machines are complemented by complementary equipment including Vacuum De-aeration Units for removing gases from liquids and pasty products, and Lubricant Processing Units for greases. The company also offers Customised Machinery for specific processing needs, alongside services such as machine lending (pucLab) for trial before purchase, and an Engineering Centre for scaling from laboratory to production. The machines serve industrial processes including emulsifying, dispersing, homogenizing, wet milling, micro-comminution, and de-aeration across pharmaceutical, food & beverage, chemical, petrochemical, and cosmetics industries.

Direct peers

• Hosokawa Alpine: German division of Hosokawa Micron Group producing mills, classifiers, and mixers for fine and ultra-fine processing. Competes with PUC in wet milling and dispersing across process industries.
• Kinematica: Swiss manufacturer of homogenizing, mixing, and dispersing equipment for laboratory and industrial wet-processing applications. A smaller niche peer with overlapping product functionality.
• Silverson Machines: UK/US manufacturer of high-shear mixers, homogenizers, and inline mixers widely used in cosmetics, food, pharmaceutical, and chemical processing. Comparable niche footprint and customer base to PUC.
• Charles Ross & Son: US manufacturer of industrial mixers, blenders, and high-shear homogenizers used in pharmaceutical, food, cosmetics, and chemical processing. Comparable product set and customer base to PUC.
• NETZSCH Feinmahltechnik: German specialist in wet and dry grinding, dispersing, and mixing equipment for chemical, pharmaceutical, food, and ceramics applications. Directly comparable product scope to PUC's mills and mixers.
• FrymaKoruma (ProXES Group): Swiss/German specialist in colloid mills, bead mills, and homogenizers for liquid and semi-liquid processing. ProXES' FrymaKoruma brand competes head-to-head with PUC's colloid mills in pharma, food, and cosmetics applications.
• IKA-Works: German-based manufacturer of laboratory and process mixing, homogenizing, and milling equipment. IKA overlaps directly with PUC in wet-processing machines and serves many of the same pharmaceutical, food, and cosmetics customers.

Broad incumbents

• GEA Group: Large German industrial group with mechanical separation, homogenization, and liquid processing equipment divisions serving food, dairy, pharma, and chemical customers. Far broader portfolio but overlaps with PUC at the process-equipment level.
• Bühler Group: Large Swiss manufacturer of processing equipment for food, feed, and advanced materials. Much larger and more diversified, but its wet-milling and mixing lines compete with PUC in food and chemical processing.
• SPX Flow: US-based manufacturer of mixing, blending, and process equipment (including APV and Lightnin brands) for food, beverage, dairy, and industrial customers. Larger and more diversified, with overlapping process-equipment offerings.
