L-Series Oil Filled Rewindable

L-SERIES-Oil-Filled-Rewindable-Motors

C.R.I.'s L – Series motors are developed with diligence complying with all safety standards and giving importance to the customers need. All the components that are in contact with water is made of AISI 304 Stainless Steel. The motor is prefilled with edible grade oil which acts as coolant as well as lubricant and heat dissipation media. Dynamically balanced rotor of these 'L' series motors are equipped with quality ball bearing maintain uniform clearance thereby giving better efficiency and increase the life cycle. The shaft extension is made of 300 series Stainless Steel to avoid splines worn out. High quality carbon / ceramic mechanic seal and oil seal made of Nitrile rubber and used to ensure better sealing system. For easy maintenance and safe handling plug in type removable cable leads are provided. Mounting dimension of Motors are accordance with NEMA standard.
