We lost 3 valves in two weeks. Guess what? BD can not ship them? Obviously they fail faster than the manufacturer can produce them.

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.

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 On Jan 31, 2008 3:35 PM, William King <wking@aecom.yu.edu> wrote: I'm curious to know if anybody else has had problems with their Aira pumps overheating and, if so, how was the issue resolved? The pumps that I'm referring to are the ones inside the fluidic cart, behind the access door, in the upper right corner. We have had the 2 upper pumps replaced twice. In addition, the circuit board that controls the pumps has been replaced and the issue has remained. The service engineer said that he would replace the cable between the pump and the circuit board, however, this has not happened as yet and I doubt that this will be the solution to the problem. The upper pump is so hot that you cannot hold your finger on it for more than a second and I fear that there will be a fire or that the pump will fail in the middle of a sort. Today there was an unusual smell coming from the instrument when it was turned on. Any ideas from anyone? William ________________________________________________________________ C.
