I just noticed that two of my three, 5 month old March Pumps have started squealing. Are they telling me they need lubrication? They were not being run dry either.
Man... odd
Like BB said, Id check the impeller, if it is that annoyingly high pitched screaming that some hear when they run them dry out of the box
Id also take this opportunity lube them.
Mine has been in service for 2 years and not a squeal, ithas been hanging pump head down for 1 year as well.
Let us know what you find... odd.
What I am wondering is if the guy I got them from ran them dry to test them when he first got them and ran them a little to long causing the impeller to heat up and damage it. We will find out shortly.
Mine squeal occasionally. I probably used them for 4 years before having any problems, and I always flush them after my brew sessions (which tend to be twice a month). For those unfamiliar, this is not a small or insignificant noise. The squeal is deafening, so much so that I have to turn the pump off regardless of where I'm at in the brew process.
I took my pumps back to Morebeer. I disassembled the head with Reagan, and we found a clean impeller. We removed it, and the pump ran smooth and quiet. A little keg lube on the shaft, and problem solved.
Since then I found the pumps might squeal every 10 brews or so....but they were quieted by the same fix of lubing the shaft. However, last time I pulled the heads apart I noticed one of the gaskets between the impeller and pumb body was worn very thin. I called March, they sent 2 replacement for something like $.075. I replaced the gaskets and lubed the shaft again. That was early '08...I don't think I've had problem since.
