Customer Service

Whether you need service on existing equipment, changes to your control system programming, or pump selection assistance, we want to help. When you call L.W. Allen, you will be greeted by our administrative assistant and project coordinator. They will guide you through initial questions and direct you to the appropriate department.

From there, you can talk with a service manager who may be able to solve your problem over the phone, and at no charge! You can schedule a service technician for an onsite repair, get a pump quotation or call for design assistance with a pump or control application. The point is, when you work with L.W. Allen, we become your “one-stop shop” for all things pump, control, SCADA, and instrumentation.


Pump selection can be complicated. We are here to assist you in selecting the right products for the job. Our sales team has an average of 19 years experience in providing customers with pump and control solutions. Our Municipal Market sales team can provide quotes for pumps, valves, gates, and prepackaged systems for aftermarket replacement or upgrade. We have two Wisconsin licensed Professional Civil Engineers who can assist with product selection, application, and quotation for facility upgrades and bid jobs.

Our Altronex division has three salesmen on staff to provide assistance with electrical control system design, bid quotation, and control product information for Municipal market water and wastewater systems.

Our Industrial Market salesmen can provide quotations, applications assistance, as well as emergency pickup or delivery for your immediate pump repair or replacement needs. We have a large stock of pumps and parts to help keep your downtime to a minimum.
