RE: Aria pumps overheating

We've had problems with that too with the same explanation and fix. On ours
the tubing above the pump actually melted! That's happend twice now and we
had a whole lot of sheath fluid on the floor and squirting all over the
inside of the cart. We had the same fix, replacing values which were sticking
and causing the pump to overheat as a result. Nothing preventative I can tell
you, although seems like the tubing needs to be shielded from the pump when
it overheats like that.

Hi William,
 
We have had this problem as well in the past.  One or both of the pumps were
replaced but the problem kept coming back.  The service tech. finally
determined that it was actually a problem with one of the valves (if I
remember correctly).  There are four valves in a row with a fifth one
slightly offset just below and to the left of the pumps.  The fifth valve has
an extra port coming out of the back.  It was that valve that needed to be
replaced, I think.  It may have been that it wasn't allowing enough of fluid
to get to the pump causing it to overheat.  Anyway, the bottom line was that
in our case, it was a valve problem and not any problem with the pump.
 
Good luck,
 
Jay

anyone?
