Rewindable motor CS, CS-R series
The CS-R 6/8/10" motors are in a water bath with the wire being coated with polyvinyl chloride, while the CS 4” motors have a special food grade dielectric fluid that gives a better lubricant effect, increasing the life of all moving parts and the copper wires.
The special design of all our motors allows easy access to the various components, simplifying maintenance and repair. All the CS,CS-R motors can be rewound and they are NEMA STANDARD.CS, CS-R: Standard construction.I-CS, I-CS-R: AISI 316 construction.
Encapsulated motor FK series
The FK motors, manufactured to ISO 9001 standards feature an hermetically sealed stator, where the self healing stator resin prevents motor burn out.They are designed for high electrical efficiency, low cost, and non contaminating water-filled design. Water lubricated thrust and radial bearings allow a maintenance free operation. A special diaphragm ensures pressure compensation inside the motor.For facilitating the connection, removable “Water Bloc” lead connector is used and for increasing the performance in sand the FK 6/8” have a sand fighter with SiC-Mechanical Seal.FK: Standard construction.I-FK: AISI 316 construction.
