Adding Cable Connector to Facilitate Pump Removal/Maintenance

[crs751]

I have four (4) Tunze 6055 pumps providing flow in my tank for years. I've replaced the pump motor on two (2) of the pumps with the only remaining maintenance being cleaning them. The only issue I have with these pumps is that to remove them from the tank to a service sink to clean them requires me to disconnect the power supply from the controller and remove the controller, cable and pump for service. This proves to be cumbersome in my setup. During one of the pump motor changes I noticed that there is a MOLEX connector that ties the cables to the board in the controller. My thought was that if it was permissible to cut the control cable and add Male/Female MOLEX connectors in the cable run, i could disconnect the cable at this location and remove only the pump for service/cleaning. Is this a viable solution or would it affect how the pump performs?

If you can buy the connector you can extend it.

There are several caveats here-

1) Were these connectors to ever be connected/disconnected when energized, the motor and controller could be destroyed, likewise if they get wet.

2) Any extension of the wiring could result in signal loss and failure to operate.

It is possible but the main reason it was done this way was to protect the connector. Generally, it should be possible to just clean them at the tank in a bucket of vinegar and water. That is what I generally do. On the newest models of pump with 7020 controller, the pump connects externally to the controller with a waterproof connector.

Thanks for the replies. To clarify, I am not extending the cable. I am cutting the existing cable at some predetermined distance so that I can remove the pump from the cable connector to the pump for remote cleaning. And I always turn off the power to the controllers before removing the pumps and will continue to do so after this modification is completed.
