Submersible motors The Calpeda 4", 6", 8" and 10" submersible motors are buiH using advanced technology and components of superior qua- lity that they ensure good mechanical strength and excellent electrical reliability. The good performances are guaranteed thanks to strict tests of all the different components during the various production 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 I-CS, l-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 maintenan- ce free operation. A special diaphragm ensures pressure com- pensation 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.
