The Calpeda 4”, 6”, 8” and 10" submersible motors are builtusing advanced technology and components of superior qua-lity that they ensure good mechanical strength and excellentelectrical reliability.The good performances are guaranteed thanks to strict testsof all the different components during the various productionphases.
Rewindable motor CS seriesThe CS 6/8/10" motors are in a water bath with the wire beingcoated with polyvinyl chloride, while the CS 4” motors have aspecial food grade dielectric fluid that gives a better lubricanteffect, increasing the life of all moving parts and the copperwires.The special design of all our motors allows easy access to thevarious components, simplifying maintenance and repair.All the CS motors can be rewound and they are NEMA STAN-DARD.
CS: Standard construction.I-CS: AISI 316 construction.
Encapsulated motor FK seriesThe FK motors, manufactured to ISO 9001 standards featurean hermetically sealed stator, where the self healing statorresin prevents motor burn out. They are designed for high electrical efficiency, low cost, andnon 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” leadconnector is used and for increasing the performance in sandthe FK 6/8” have a sand fighter with SiC-Mechanical Seal.

- Against short-circuits and overloads to the electric pumps system we advise to follow the usually applied normative.- To avoid a possible dry working of the electric pump in is better to install a level control.- In order to avoid overheatings, tension grops above 3%, we advise to use suitable starting motors systems.- All the cable wave to respect the usually applied normative and to present excellent insullation characteristics.
The tables show the maximum length of the cable depending on the current absorbed by the motor and the cross section area of the cable, at diffe-rent voltages. The maximum voltage drop equal to 3%, cable temperature of 80°C, water installation similar to air installation at a temperature of30°C.

For dimensioning the phase cross section area for the submersible motor need the following information:
• V: Rated voltage (V)• I: Motor current (A)• L: Length of cable (km)• cos ϕ: power factor
• Ambient temperature (°C)
The choice of the minimum cross section area of the phase conductor is determined by the rated motor current and the values reported in Table 1.
The maximum current of the cables listed in Table 1 are for ambient temperature of 30 ° C. When the temperature is different, the maximum current of the cables should be corrected by a factor given in Table 2.
The cross section area of the phase conductor is choosen by checking the voltage drop along the line , through the following equation:
DU% = 1,73*I*L*(R*cos ϕ+X*sen ϕ)/(V*1000)
DU% the voltage drop should not be greater than 3%R, X = cable resistance and reactance in ohms/km (indicated in Table 1)
senϕ = √ 1-cosϕ
In case of star / delta starting the rated current of the motor should be divided by 1.73.
* Up to 35 mm2 sections four-wire cable are used, from 50 mm2 single core cables are recommended as well.Tab.1

When the submersible motor is installed :
- below the well inlet points (picture A);- in tanks, lakes, basins, etc… (pictures B and C)
an external jacket must be installed to create acooling flow around the motor. Only in this waya safe operation can be assured avoiding anyoverheating which can damage the motor.
