A smart young businessman named James B Tuthill recognised a good opportunity when he saw one and purchased a quarry and kiln and began supplying Chicago common bricks to local builders Manufacturing Alsip Chicago Illinois Manufacturing Tuthill’s modern manufacturing systems follow the Toyota principles along with “Lean Manufacturing” techniques. The main facility is in Alsip, Chicago, Illinois in the USA. Our European manufacturing centre is at Ilkeston, Derbyshire, England there are also offices in South America, mainland Europe, China and Australia. From all of these locations we supply a global network of distributors. An entrepreneur at heart, Tuthill searched for an efficient way to lift the clay from the quarry floor and deliver the companies bricks to the construction sites. Enquiries turned up a new idea, a steam powered truck. However the design proved unworkable, but Tuthill salvaged the engines only good feature, a small internal gear pump which injected fuel directly into the trucks boiler. Tuthill refined the pump design and marketed it to the producers of boilers. The Tuthill internal gear pump was widely accepted, proved itself successful and thus became the foundation for the Tuthill Corporation. To concentrate on growing this business Tuthill Pump Group was established in 1927. Pumps that trace their design directly back to the original model are still produced in quantity today and can be found in every corner of the globe. Manufacturing Ilkeston Derbyshire England
