Pump Motor Repairs and Rewinds

Since 1950, the team of pump system experts at AC Electric has met the needs of the commercial and industrial markets throughout Maine and the northeast.

Many pump systems include electric drive motors, and it is common for these pump motors to need repair alongside the pumps themselves. AC Electric does a large volume of pump motor repairs each year and considers pump motor repair and rewind one of its core services.

AC Electric provides an array of in-house pump repair capabilities as well repair to other electrical and mechanical products.  We offer pickup and delivery services and our friendly team members will handle the disconnection and removal of equipment from your water system.
