There are several pumps available that might fit the function.

I have a Crosby 1/2 HP DC refrigerator/freezer on my boat, which
normally runs
an hour or 2 a day. Shortly before I hauled out for the winter, I
found the
system in dire straights. I'm not sure about the "cause and effect" but
the
belt was very, very loose, it was making bad sounds, and I didn't think
it was
pumping water. I tightened the belt, but it was then overheating, and I
didn't
think the water pump was running.
At the time I thought maybe the pump had died from running continuously,
perhaps
running dry, so I brought it home for dissection. I finally got around
to
checking it out. Its a "March 809 BR" with the inline bronze head.
When I run
it without the head, it spins and hums. When run with the head it make
a
horrible, screeching noise. Is that simply because its running dry, or
does it
need more help? Nothing looks obviously bad, but the shaft holding the
vanes
seems to have uneven wear.
As long as I have it all apart, is there a better pump that I might use?
This
is below the waterline, and needs help priming. Its possible that
losing prime
was the trigger for my current problems. I do like the fact that this
is quiet
and small, because it lives under the floorboards in my kid cabin.
Any comments appreciated,
Jeff
