What Allweiler does

Allweiler, headquartered in Radolfzell, Germany, is a 160-year-old industrial pump manufacturer (founded 1860) operating as a wholly-owned brand within CIRCOR International (NYSE: CIR). It designs, manufactures, and services a broad portfolio of centrifugal and positive-displacement pumps — including three-screw, twin-screw, progressing cavity, internal gear, herringbone gear, and precision gear pumps — many qualified to API 676 and optionally API 682, serving industrial manufacturing, oil & gas, marine, and water/environmental customers. The company operates a proprietary foundry producing specialty castings available only through Allweiler, and as of 2025 has formally consolidated IMO (screw pumps) and Houttuin (twin-screw pumps) as sub-brands within its portfolio.

Allweiler's go-to-market is enterprise field sales executed through CIRCOR's international sales infrastructure, augmented by on-site technical advisory, a Pump Showroom, multilingual support (English, German, Simplified Chinese), and a service/aftermarket network including OEM-certified parts, emergency stock pumps in Norway and Radolfzell, service engineering, and pump recycling. Revenue is generated primarily through hardware sales of pump units supplemented by a recurring aftermarket parts and service stream. The company holds no AI or software-exposed products in the disclosed data set; its competitive differentiation rests on mechanical engineering heritage, proprietary materials, API-standard compliance, and the breadth of its installed-base service network.

The customer base spans large enterprise accounts across heavy-industrial segments, with Bilfinger Engineering & Technologies disclosed as a named partner for marine exhaust gas cleaning systems. Geographic reach is global via CIRCOR's distribution, with active emphasis on Europe and visible market posture toward China through localized web presence. Pricing is not publicly disclosed; quotes are handled direct via CIRCOR sales channels.
