The solution to the leakage in the mechanical seals of the propylene pump;

The reasons for easy bearing damage and often mechanical seal disabled of propylene pump are analyzed and studied, after the improvement with bearing structure and one year of running, it indicates that the improvement is proper and effective.

Failures of the series connection mechanical seal on the propylene pump were analyzed.

Reason and improvehent measure for sealing and leakage of polypropylene machine pump;
