Calpeda Motors


The Calpeda 4", 6", 8" and 10" submersible motors are built using advanced technology and components of superior qua-lity that they ensure good mechanical strength and excellent electrical reliability.
The 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 6", 8" e 10" motors are in a water bath with the wire being coated with polyvinyl chloride.
All the Calpeda motors can be rewound and they are NEMA STANDARD.
