Thanks again....
This application is for a Water Fall on the facility entrance ponds and the pump is only submerged 8 feet but the lead to the control panel is 25 feet.
Thanks for the great responses...

so it is also water cooled. However, the total system cost is at $12,000 now and we do need to protect the investment as best we can.
I have a proposal to install a replacement (~pump cost = $4,000) 10 Hp water pumping system which is serviced with an Open Delta three phase 240 volt 50 KW utility supply. The old system has experienced three motor burn-outs in the last 4 years. The new motor is rated at 10 Hp, 230 volt, three...
