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.
