4" Rewindable Oil Filled Motors - L Series
C.R.I. “L Series” motors are high-performance, rewindable submersible motors designed for deep well and borehole applications. Engineered for reliability and longevity, these motors are pre-filled with non-toxic, edible-grade oil to ensure efficient cooling and superior lubrication, making them ideal for continuous operation with low operating cost.
These motors are suitable for installations up to 150 meters deep and are available in both single-phase and three-phase power supply configurations, offering flexibility across a wide range of applications. The internal design includes rotors supported by ball and angular contact bearings, which are specifically built to endure high axial and radial thrust loads for consistent operation in demanding environments.
Built to meet NEMA standards, all mounting dimensions ensure compatibility and ease of installation with standard pumps.
