Why are there rubber shavings underneath the pump coupling?
The most common cause is the poor alignment of the pump and motor shafts. This condition may be corrected by the use of a dial indicator (or such alignment device) to indicate any amounts of misalignment. Since the rubber insert is actually the weakest point of a pump coupling, it handles the misalignment thus preventing premature damage to other rotation parts of the equipment.
