Put grease in the impeller housing when you first install. Normally water lubricates it but this also makes it easier to re-install the new impeller when you slide the housing down over it, and discourage damage to the new pump if pulling over dry.
You only need to put a dab of grease in there not a huge amount. Once it rotates a couple of revolutions it will be spread all over the place.
