A company in Woonsocket, RI contacted Luther's Welding & Fabrications to manufacture two centrifugal pump impellers for a medical waste application. The impeller had to be precisely designed and fabricated to ensure superior wear resistance and consistent performance over time.

For this project, we designed the impeller using SolidWorks. The material was hot rolled steel, chosen for its ability to provide good resistance to abrasion and therefore a longer blade life, which is very important to a pump that is removing solid medical waste. The overall dimensions of the impeller were 32.876" in diameter, 11" height (without blades), and would be equipped with 5" hubs.

Several of our cutting-edge, large capacity CNC machining centers were used to process these parts. Metal cutting was performed with our CNC plasma cutter and metal forming was accomplished on our 135 ton 144" long press brake. Other machining processes, including broaching, were also used.

Armed with highly skilled TIG welders certified in ABS, GTAW, GMAW, and SMAW standards, our welding experts meticulously located the impeller blades to be equally spaced and perfectly balanced to ensure stability, vibration control, and overall centrifugal efficiency.

At Luther’s Welding & Fabrications, we have a reputation for quality workmanship and customer service that is recognized throughout the industry. We deliver superior products that meet customer specifications as well as standards and guidelines for European CE, and NMMA.
