Check the wear trace, failure analysis can help the seals.
1, wear wider: indicates that there had been a terrible wrong pump.
The reason is: bearing damage;Shaft vibration or shaft deformation;Shaft bending;Pump cavitation vibration;In the coupling of;The pipe serious deformation;Seal static ring tilt.
2, narrow grinding crack: grinding crack than two sealing surface minimum width narrow, this shows that overpressure sealing, pressure or temperature deformation of the sealing surface.
3, no grinding marks: sealing surface is not adhesive.Check whether spring compensation institution such as sliding or hampered.
