CentriPro : 4” Submersible Motors

Submersible motors are suitable for 4” or more wells or applications

The CentriPro submersible motors are suitable for wells or applications which have an internal diameter of 4” or more. They are designed for use with submersible centrifugal and peripheral pumps having 4” NEMA coupling dimensions. The single phase versions are of PSC (Permanent Split Capacitor) design with the capacitor connected permanently and located in the corresponding control box. The stator windings are rewindable and along with the rotor and bearings are cooled and lubricated in a non-toxic FDA approved oil bath.
