A Past, Present and Future Propelled by Growth



A fire-extinguishing pump built by Gotthard Allweiler in 1865

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.

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.
