HOW MUST SUBMERSIBLE PUMPS BE INSTALLED TO PREVENT FAILURES?
Without running level electrodes and level relays but avoiding «dry running»
With motor protection against overloads with thermal memory
With protection against overvoltage, phase loss and incorrect phase sequence
With shorcircuit protection
Fanox control panels for three-phase and single-phase submersible pump protection provide the overall solution to these problems by using the motor as a sensor .
By measuring the motor's parameters, they detect «dry running» before it occurs; this is achieved without the need for awkward kevek elektrodes, therefore, saving time and Money in their installation.
Additionally, they protect the motor against overload blodcked rotor, overvoltage, phase loos and incorrect phase sequence.
Once the pump has stopped, the control panel waits for a certain time (reset timing) before restarting it automatically, allowing the well to recover.
Also suitable for old installations. In already operating installations, a fault in the level electrodes, may mean having to remove the pump from the well even if it is working adquately. In this case, the problem can be solved by replacing the old panel by a FANOX panel, without the need to extract the pump.
