OP3 inch Pump Motor

SMALL SIZE, GREAT QUALITY - 3" Rewindable OIL filled submersible motor.

The OP3-type is the outcome of consistent design effort arousing from the need to solve all problems linked to reduced space.

The motor still preserves the splined-shaft coupling system typical of the NEMA regulations.

The OP3-type motor still preserves the splined-shaft coupling system typical of the NEMA regulations.  The electromechanical specifications are undoubtedly interesting and complying with all application requirements.  Each motor is supplied with a 1.8 mt-long sealed cable directly connected with the winding.
