Potential cause of Mechanical Seal failure

As study shown, mechanical failures contribute 24% of all mechanical seal failures.

Here I listed that 4 area that you need to pay attention to.

1) Alignment of pump

Shaft misalignment, coupling imbalance, and impeller imbalance can all contribute to mechanical seal failures.

2) Piping strain the pump

In addition, after the pump is installed, if you have misaligned pipes bolted to it, you will impart a lot of strain on the pump.

3) Pump foundation

You also need to avoid a bad base: Is the base secure? Is it grouted properly? Do you have a soft foot? Is it bolted correctly?

4) The right bearings

And last, check the bearings. If the tolerance of the bearings wears thin, the shafts will move and cause vibrations in the pump.
