L.W. Allen Pump Systems

L.W. Allen, Inc. is a full-service distributor of pump and control products in Madison, Wisconsin with a long history of serving the municipal water and wastewater industry in the upper Midwest. The company was founded by Lou Allen. He began his career in 1927 working for Fairbanks Morse, a company manufacturing pumps and scales in Beloit, Wisconsin. Fairbanks Morse moved their pump production to Kansas City, Kansas, and Lou decided to remain in Wisconsin and open his own distributorship.

In November of 1961, Lou began L.W. Allen, Inc., a distribution company for several well-known pump products, including Fairbanks Morse. His incorporation in the State of Wisconsin marked the beginning of more than 50 years of sales and service under our current name. During that time, we have stayed focused on providing a very personalized level of service to the end-users, consulting engineers, and contractors who rely on us for quality equipment and support.


In 1971, we formed Altronex, a division of L.W. Allen. Altronex is our electrical controls group providing a wide range of custom-designed control systems for automation, supervision, and monitoring of pump equipment, flow control, and related processes. We manufacture control systems in-house under the Altronex brand name. These systems are all engineered, built, programmed, and tested in our UL508 and UL698 (Intrinsic) certified production facility in Madison, Wisconsin.


Growth in both the pump division and the electrical division resulted in a move to a larger building in 1990 doubling our size. That move, into what is now our current location at 4633 Tompkins Drive, was followed by a warehouse expansion in 1997.


Today, L.W. Allen and Altronex offer high-quality, flow-related products and control systems along with the most experienced service and support staff in the industry. We believe our most valuable assets are our people. We have 37 expert employees here to help you. Our employees average more than 14 years of experience with L.W. Allen, Inc.
