Identifying the root cause failure of the defected pump.

The width of pump housing at center bearings. The defected pump case.

As a result of pump housing weakness comparing with the previous versions of same pump which carries all the radial and axial loads, a sudden crack occurred at the pump housing main supports. That crack resulting in excessive heat for main and center bearings..

That mentioned crack in pump housing cause a seriuous damage for the two main bearings and the two center bearings..

the crankshaft also had several scratches and defects, causing pump S/D due to overheat..
