In 1860, Gotthard Allweiler invented the fire-fighting wing pump, filling a market gap. Nearly 160 years later, 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.
