I’m in the process of evaluating a wet stator (motor ) pump vs. a conventional canned pump for an application where the pressure is approx. 1200 psig and the temp is 130 °F. The motor power is approx. 100 hp. The pumped fluid is radioactive and somewhat dirty but there will be clean purge water introduced between the pump and the motor at a pressure slightly higher than inlet, thus keeping the motor section fairly clean.
Does anyone have any experience with wet stator motors? I was told that even though the insulation systems for wet stator motors have been well developed, and not subject to environmental degradation, there is still a need to perform periodic maintenance to clean the windings. Any other known advantages/disadvantages of the wet stator vs. the canned motor would be appreciated.
