Common cause of Regrinding cyclone pumps shaft failure

Common cause of pump shaft failure is due to breakage caused by the pump ingesting hard particles or foreign objects(Balls,etc).

If the pump shaft does not break from the sudden impact, it could still fail in the near future due to stress cracks. In some instances the hard particles(Balls,etc) will distort the impeller and cause the pump shaft to have excessive run out.

This will result in the impeller rubbing and literally gouging or imbedding itself into the pumps wear ring liner. This excessive force can easily break the pump shaft.

While it is not possible to eliminate this problem, regular inspection and maintenance will extend life and allow for replacement before it becomes a problem and ruins & outing.
