ATTENTION
If operation of this pump is critical to your business, we strongly
recommend you keep a spare pump or major repair kit in stock at all times.
As a minimum, a minor repair kit (O-rings, gaskets, shaft seal and bearings)
should be kept in stock so pump refurbishment after internal inspection can
be accomplished.
