Unibloc Hygienic Technologies

What Unibloc Hygienic Technologies does

Unibloc Hygienic Technologies (UHT) is a Kennesaw, Georgia-based manufacturer of precision-engineered positive displacement pumps and complementary flow control products built for hygienic processing environments. Founded in 1984 by Harry Soderstrom as Unibloc Pump, the company has been a portfolio company of Chicago-based private equity firm May River Capital since January 2021 and was rebranded Unibloc Hygienic Technologies in April 2022 to reflect an expanded brand family. Following the January 2026 launch of its twin screw pump line, UHT is the only major manufacturer offering all four primary hygienic pump technologies — lobe, gear, air-operated double-diaphragm (AODD), and twin screw — alongside flow control accessories such as valves, strainers, sight glasses, drum pumps, and bubble traps, organized under four sub-brands (Unibloc Pumps, Flotronic One-Nut, Hygenitec, Standard Pump).

UHT's core technology rests on patented mechanical designs that simplify maintenance and cleaning: QuickStrip tool-free disassembly, One-Nut single-bolt AODD construction, the FlushCap CIP-compatible bearing, bolt-free rotors, and the Guardian Alarm diaphragm rupture protection system. The company manufactures at facilities in Kennesaw and Duluth, Georgia, Beckum, Germany, and Bolney and Hailsham in the UK, vertically integrating CNC machining through its March 2023 Metaltech Precision Engineers acquisition. Products carry 3A sanitary certification, ISO 9001 quality certification, and FDA-compliant materials, addressing regulated hygienic applications.

UHT sells to enterprise customers in food and beverage, dairy, bakery and confection, meat and poultry, pharmaceutical and biotechnology, beauty and personal care, transportation and tanker fleets, and general industrial processing. Commercial operations are run through direct field sales in the Americas and Europe, supported by an engineering center of excellence in Bolney and a global distribution network inherited from Standard Pump that reaches more than 50 countries. The company does not disclose public pricing; transactions are quote-based, with applications engineering, replacement parts, and spares forming recurring revenue streams alongside hardware sales.

Broad incumbents

• Alfa Laval: Global Swedish process equipment giant with a broad hygienic pump and fluid handling portfolio (lobe, centrifugal, etc.) serving food, dairy, pharma, and beverage. Directly comparable as a multi-technology hygienic pump incumbent, though significantly larger and more diversified than Unibloc.
• IDEX Corporation: U.S. industrial conglomerate owning Wilden, PSG, and Warren Rupp, all of which serve sanitary and industrial AODD pump markets. Direct peer in hygienic diaphragm pumps and highly comparable to Unibloc's Flotronic AODD line, with broader portfolio across multiple pump technologies.
• GEA Group: German process technology major with extensive separation, homogenization, and pumping offerings for dairy, food, beverage, and pharma. Overlaps Unibloc in hygienic positive displacement pumps and CIP-compatible equipment, but operates at much larger scale and across full processing lines.
• ITT Inc. U.S. industrial manufacturer with a Richelieu Food and Process Group offering hygienic and sanitary pumps. Overlaps Unibloc's hygienic positive displacement pumps and serves similar food, dairy, and beverage customers, though as part of a much larger diversified portfolio.
• SPX FLOW: U.S.-based processor of pumps, mixers, and hygienic flow equipment under brands like APV, Waukesha Cherry-Burrell, and Lightnin. Directly comparable to Unibloc's hygienic/sanitary pump and flow control accessory portfolio, with much broader installed base across food, beverage, and pharma.

Direct peers

• Fristam Pumps: U.S. manufacturer of sanitary centrifugal and positive displacement pumps (incl. Waukesha-style lobe pumps) for dairy, food, beverage, and pharma. Closest direct U.S. peer to Unibloc's hygienic lobe pump line, competing on similar 3A-certified equipment in food processing plants.
• Vogelsang GmbH & Co. KG: German specialist in rotary lobe, screw, and progressive cavity pumps for wastewater, biogas, agricultural, and industrial applications. Comparable to Unibloc's twin screw and lobe pump portfolio, particularly relevant in hygienic/industrial overlap segments.
• Tapflo Group: Swedish manufacturer of hygienic and industrial diaphragm (AODD), centrifugal, and peristaltic pumps distributed globally. Closely comparable to Flotronic's AODD range and Unibloc's hygienic pump applications across food, pharma, and chemical markets.
• Verder Group: Dutch specialty pump manufacturer offering hygienic centrifugal, diaphragm, lobe, and peristaltic pumps. Directly comparable to Unibloc's hygienic positive displacement pump range, serving overlapping food, pharma, and chemical end markets globally.

Emerging players

• Watson-Marlow (Spirax Group): UK-based specialist in peristaltic pumps and fluid path solutions for pharma, biotech, and food applications. Comparable to Unibloc's hygienic product strategy and shares strong 3A/FDA compliance orientation, though focused on peristaltic rather than lobe/AODD/twin screw technologies.
