Our demand for quality includes 100% inspection of all components produced, including those structural components made at specialized regional fabrication facilities.

The Aurora manufacturing facility consists of approximately 20,000 square feet of office and engineering area and over 75,000 square feet of enclosed manufacturing area with approximately six acres of yard facilities, storage sheds, and outside cranes. This facility permits total in-house manufacture and assembly of the most demanding components, including Spur Gear and Worm Gear Drives, Rotating Biological Contractors (RBCs), Digester Mixers, Boiler / Heat Exchangers, Rotary Distributors, and more.

We maintain a highly skilled work force that performs all the tasks necessary to produce our products including burning and (AWS) welding of plate and structural fabrications, machining, assembly, sandblasting, painting and inspection. Walker Process Equipment holds an ASME "U" stamp for manufacturing of heat exchangers as applied to this industry. We are a company Member of The American Gear Manufacturers Association (AGMA).

A formal Quality Assurance program is in place, which was first audited and approved on October 6, 1974, by ASME Board and Hartford Insurance. In addition to this manufacturing facility, Walker Process Equipment uses many outside structural steel fabricators all over the United States, where economics dictate production of large steel structures close to jobsites, to reduce the freight component. In these cases, as well as our own in-house manufacture, 100% inspection is conducted by qualified, Aurora-based inspectors.

Our engineering staff includes licensed professional engineers of various disciplines, and drafters, many with over twenty years of experience in this industry. The department is equipped with state-of-the-art engineering tools including various engineering software packages, including structural analysis and finite element analysis. Both Project Management and Field Service are included within the engineering department. A project manager is assigned to each project and keeps the Customer informed on a regular basis of the project`s status. Field service technicians are highly skilled and available for start-up, training and trouble-shooting services.

Our Parts Department maintains records of every piece of equipment we have provided, now numbering well over 10,000 equipment installations. We are proud of our ability and resolve to provide repair parts to our Customers to meet emergency and preventive maintenance needs in a timely manner. All work in progress is assigned to a Project Manager, who provides the Customer with an on-going communication aimed at providing full and complete project information and to assist in maintaining the schedules to ensure "on-time performance" and Customer satisfaction.

Many of Walker`s installations continue to operate after 40 – 50 years of continuous service as a result of our comprehensive engineering and desire for quality at every step of manufacturing. Our products are designed and manufactured based on our 60+ years of experience combined with the most advanced engineering know-how. All key components of Walker`s products are manufactured at our facility in Aurora, IL.

Our in-house sales engineers work with our nationwide network of Sales Representatives and if contacted directly will be pleased discuss your specific requirements. For detailed information or assistance, contact our Representative in your area or our home office.
