Rev. 3/23/2018

Evaluation:

On Monday, February 26, 2018, Flow-Technics’ Service Technicians located to the evaluation site to begin the evaluation/tear down of Pump #2, VUPX 1001 serial number

58885.

Motor cover and cables were removed. Cables checked good. Stator megs grounded.

Pulled stator off of pump and found stator blown on the lower end. The stator did not short out to the rotor.

The stator was brought to Joliet Equipment for inspection. It was found that there was apparent winding failure.

The pump stator failed to ground at the end of a slot. This type of failure is typically due to either a failure in the insulation or moisture related. The winding does not appear to have been overloaded or single phased.

Conclusion:

Based on the evaluation and inspection of the pump/motor it is concluded that the pump requires twelve (12) new one hole lug compression connectors as the stator leads were cut to remove the stator and they need to be re-terminated (see attached datasheet). Also, the stator needs to be reconditioned which includes rewinding of stator, VPI and dip overcoat winding and paint. The total cost for recommended repairs/parts is $ 19,224.00

(see chart for part listing).
