Mystery Delta Motor

[Rockyd]

Have a couple of pumps of unknown Horsepower that are Delta wound (FLYGT brand) from the 70's that I believe are 7 to 10 HP (best guestimate) that have external starters on stands with Appleton 60 amp 460vac plugs attached. there are a couple of other pieces of machinery that are part of the machinery he needs to set up a shaker/screening plant for mining.
Not seeing the smaller motor(s) on the shaker drawing much load.

Anyone have experience with FLYGT submersible pumps? I think they are old pumps for moving drilling mud for oil drilling rigs (they all have explosion proof fittings for C1D1) ?
He has a 65 Kw diesel generator that puts out 480/277

Thinking a 30 Kva wye/delta Transformer would be more than sufficient to meet his needs?

Might be able to upload pix from my phone....

Flygt pumps typically have an oil immersed motor, so they usually requires a specialized monitor system called a "CAS" or "MiniCAS" that connects to a probe in the motor chamber to monitor the oil for water content (leaks) and high temperature. That relay goes in the control panel for the pump and has to tie into the motor controller to shut it down if it trips. Not using it voids the warranty (if any).

The HP sizes on Flygt pumps are odd because they are made in Sweden using 380V 50Hz kW rated motors, then the HP is converted for running them on 460V 60Hz, so the HP values come out odd. For example they might use a standard 5.5kW 380V 50Hz motor which would be roughly 7.5HP, but when used at 460V 60Hz, the higher speed results in it being 8.8HP. So when sizing the conductors per the NEC requirements using the HP tables, you have to use the next standard HP size larger.

I have seen them as Xylem Water Solutions USA, Inc. Flygt Products........

Thanks for the replies, I at least have a game plan for going forward to test the equipment.
