Series 100 pump when running has a hesistation in it that more than likely caused the destruction of the pcast iron coupler

Pump is two years old?

Any ideas causing the hesistation?

    was it oiled

    when installed? Sounds like the bearing are seizing up. 3 oil cups, a few drops each on the motor, the rest of the plastic vial in the bearing wicking.

    Or something stuck in the impeller, solder, stones, copper reamings, etc.

    Spring coupler

    A common cause of premature wear is misalignment of the motor itself. Motor mounts eventually wear and out of wack causing stress on the coupler. Also, as Matt stated it is very important that the pump be oiled upon start up as to the manufacturers reccomendations. If it was under oiled, especially the bearing assy, the damage is already done.

    Taco pumps are pre lubricated

    sounds like the B&G coupler that failed. Taco uses a spring type coupler.
