Allweiler

What Allweiler does

Allweiler is a German industrial pump manufacturer founded in 1860, now operating as a wholly-owned brand within CIRCOR International, Inc. (NYSE: CIR). The company designs and manufactures progressing cavity pumps (ALLTRI series and the newly launched AE-RD/RE Hopper Pump), centrifugal pumps (NT and LV series), and additional specialty pump types for general industrial, marine, and water/wastewater treatment applications. Technical specifications cited include flow rates up to 12,000 l/min for progressing cavity pumps, differential pressures up to 16 bar, fluid temperatures up to 140°C, and viscosities up to 250,000 mm²/s, indicating a portfolio engineered for aggressive media, viscous fluids, and demanding process conditions.

The business model is hardware sales of engineered-to-application industrial pumps, with pricing conducted on a quote basis through a direct sales team and a global sales partner network accessible via a Sales Partner Finder tool. The firm segments its addressable market horizontally across General Industry and Water and Wastewater, with Marine as a secondary focus supported by dedicated emergency-pump stock in Norway. Go-to-market is enterprise field sales supplemented by digital channels including a product search portal, virtual pump showroom, case studies, and trade fair presence (IFAT 2026, MD&M West 2026). Customer support extends to application-specific engineering and emergency pump services out of the Radolfzell, Germany operations site.

Allweiler sits within the CIRCOR Pumps brand family alongside IMO and Zenith, and inherits CIRCOR's global infrastructure of over 3,100 associates across five continents. The firm-level employee count of 126 suggests the Allweiler-specific operating scope is a focused sub-unit within the parent's broader diversified industrial portfolio. Revenue, segment-level financials, and standalone P&L data for the Allweiler brand are not publicly disclosed.

Broad incumbents

• Flowserve: US-listed global pump and valve manufacturer with extensive industrial pump portfolio (including progressing cavity). Larger and broader than Allweiler, but overlaps in chemical processing, oil & gas, and water applications.
• Grundfos: Danish global pump manufacturer with strong industrial and water applications. Overlaps with Allweiler in centrifugal and process pumps, though Grundfos is more dominant in commercial/residential and less so in specialty progressing cavity pumps.
• Xylem: US-listed global water technology company with major pump operations (Flygt, Goulds, Wedeco). Strong direct overlap in water/wastewater pumping, which Allweiler's sludge/polymer progressing cavity pumps address.
• ITT Inc. US-listed industrial manufacturer with a notable pump segment (including Bornemann, a major progressing cavity pump competitor). Direct overlap in progressing cavity and screw pump categories for industrial applications.
• SPX Flow: US-listed flow technology company with industrial pump and mixing solutions. Comparable in serving process industries and overlapping in positive displacement and centrifugal pump categories.

Direct peers

• KSB: German industrial pump and valve manufacturer with comparable product breadth (centrifugal, submersible, specialty pumps) and similar European industrial customer base. Direct overlap in water/wastewater and general-industry applications.
• Sulzer: Swiss-headquartered global pump manufacturer with overlapping industrial pump lines (centrifugal, progressing cavity, submersible) serving similar chemical, water, and general-industry customers. Closest comparable in European industrial pump heritage and breadth.
• Netzsch Pumpen & Systeme: German specialist in progressing cavity pumps (Nemo brand) and other positive displacement pumps. Directly competes with Allweiler's progressing cavity pump line in viscous and aggressive media applications.
• Seepex: German specialist manufacturer of progressing cavity pumps, comparable to Allweiler's ALLTRI series. Head-to-head competitor in viscous media, chemical, and wastewater applications.

Others

• Zenith (CIRCOR brand): Sister brand under CIRCOR Pumps specializing in precision gear and metering pumps. Listed because it shares the same corporate parent and contributes to CIRCOR's overall pump portfolio economics with Allweiler.
