A History of Performance
A past, present and future propelled by growth.
For over 160 years, the Allweiler name has been synonymous with comprehensive and unrivaled
pump expertise—with an equally comprehensive product portfolio.
In 1860, Gotthard Allweiler invented the fire-fighting wing pump, filling a market gap. Nearly 160 years later, Herr Allweiler’s pioneering spirit lives on at CIRCOR. Our history is rich with technological, design and production innovations that shape modern progress and align with market needs for fluid-handling solutions around the world.
Today’s Allweiler customers benefit from the specialized pump knowledge that spans generations. Regardless of their pumped medium, they can confidently source the most suitable pump or system to handle it. That is because Allweiler pumps are precisely tailored to each industry-specific application and conform to the most stringent quality and reliability standards governing them. Unmatched reliability and efficiency of every pump is the goal of Allweiler’s accredited quality assurance system.
From establishing a company-owned foundry producing high-quality castings of materials available only through Allweiler, to achieving global leadership in both centrifugal and positive-displacement pump technology, we have delivered high technical and economic value to customers while reducing their total cost of ownership of valuable assets, decade after decade.
Now, as part of a family of time-tested CIRCOR industrial brands, Allweiler is bolstered by operating synergies and international sales structures that make the company more flexible and customer-centric than ever before. To our many customers active worldwide, we are pleased to offer all needed resources wherever their opportunities may take them. Our broad product range is augmented by personal, competent advice on-site and comprehensive service after the sale. CIRCOR speaks the languages of its customers and understands their business and regulatory requirements.
DESIGNED TO PERFORM
Featured Products
CIRCOR’s Allweiler SNA series of next-generation industrial lube oil three-screw pump systems are the ideal solution when nothing less than API-level quality will do. Engineered to last, this series is built to API 676/682 guidance and allows skid builders to offer flexible solutions, cost-effective pricing and reasonable delivery times to their customers.
Four pump sizes, One Installation Footprint. The modular setup of the AEB-DE series makes it simple for skid builders to standardize their designs without regard to flow rate and liquid characteristics.
Allweiler OptiFix has a specially designed dismounting device that enables you to remove the stator and rotor while the discharge casing and suction casing are still installed in the piping, giving it best-in-class mean time to repair (MTTR).
EMTEC-C three-screw pumps excel at moving chips and particles away from cutting surfaces both precisely and efficiently. And with its incredibly durable construction, it's a level of performance that will stand up to even the harshest environments.

CIRCOR’S German entity Allweiler GmbH received big pump order to be installed in Bilfinger Engineering & Technologies' (BET) Exhaust Gas Cleaning System for Ships.
In shipbuilding, most large vessels that are susceptible to heeling could benefit from an anti-heeling system (heeling is the term for when a ship tilts on any of its sides). The most common cause of heeling is uneven cargo loading/unloading in port, but high winds, waves, currents and turns can also cause it. Heeling can be dangerous to ships and to their passengers and cargo, so a good anti-heeling system can not only make port operations simpler, it can also make a ship safer in general.

In tunnel construction, excavation occurs two ways depending on geologic conditions at the site: by conventional drill-and-blast and by precision-operated “mills in the mountain” known as tunnel boring machines, or TBMs. The Brenner Base Tunnel through the Alps, destined to become the longest underground railway connection in the world at a planned length of 64 kilometers, is being excavated using TBMs supplied by Herrenknecht of Schwanau, Germany

PUMP RECYCLING
Sustainable and environmentally friendly pump return
Our service in Germany and UK does not stop after the pump has reached the end of its operating life. Since pumps count as electronic waste, they must be handed in at certified collection points according to law. We support you in this process. You can return the old pumps we produced to us free of charge and we will take care of the recycling process.
