There are no hard objects on the front cover of the centrifugal pump impeller, but it keeps wearing out – what causes the situation shown in the picture?

What medium is it, and is it corrosive or erosive? ?

The analysis indicates that the issue is caused by material erosion, not direct wear or corrosion; please provide details on the operating conditions and the pump structure

Please verify the shaft play and positioning dimensions of the pump rotor! Is there cavitation!

For pulp, the corrosion should not be too severe

Erosivity should be present; the conveying medium is pulp, so corrosion is not very high
