When Gotthard Allweiler invented the fire-fighting wing pump in 1860 to fill a market gap at that time, he wrote the first chapter of Allweiler’s history. Almost 160 years later, Mr. Allweiler’s pioneering spirit lives on at Circor. That history book is rich with stories of technological, design and production innovations that shaped modern progress and aligned with market needs for fluid handling solutions around the world.
Today’s Allweiler customers are beneficiaries of the specialized pump knowledge that has spread across generations. They can be assured that, whatever their pumped medium is, they can 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 to produce high quality castings of materials available only through Allweiler, to achieving global leadership in both centrifugal and positive displacement pump technology, Allweiler has 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. With many customers active around the world, Allweiler is pleased to offer them all needed resources wherever their opportunities may take them. The 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.
With more than 60% of Circor’s Industrial Group workforce of 4,000 based in Europe, and the European sites generating over half of the Group’s revenue, the Group’s world headquarters is now based right here, in Radolfzell. Circor’s commitment to the business and the region deepens customer relationships in the best tradition of Allweiler, and brings together more than 40 renowned pump, valve and accessory brands under one corporate umbrella for some of the world’s most severe service and mission critical applications.
