In-Field Service

As a factory-authorized service center, Dorner Company provides superior service throughout the Midwest on all lines we carry, including our newly expanded Pump and Chemical Feed lines.

In-Shop Service

Some repairs can’t be completed in the field and are best serviced in our shop. Dorner has the personnel and equipment to handle difficult problems that require extra attention. Customers who take advantage of in-shop service enjoy discounted service rates while forgoing costly travel and mileage charges.
