Default Chugger problems

Well I just limped through my brew day. My chugger pump keeps locking up. I really like the pump, but it can be a PITA when transfering water/wort. seems like 170 dg or higher, the magnets let go, and you hear the impeller spinning, but not pushing any water. then if you shut it down, it locks up for about 5 minutes, then it will restart. I have tried all kinds of things, different valve settings etc, no good, I have to shut it down and wait.

any ideas how to deal with this ?? anyone have a similar problem ? My fittings are all mounted in the correct direction.

Thanks. Yes. i did call last week, and spoke to Brian. He was very suppportive, and said they knew about the problem and were working on a new design that hopefully would cure the problem. I guess its somewhat normal for the magnets to disingage due to the heat.

I am kinda looking for feedback from others, on what they are doing. pumping a gallon of water, and waiting 5 minutes for the pump to unlock to pump another gallon, makes for a long brew day

My chuggers do the same thing.....hot water/wort causes them to freeze up. I actually took mine apart when hot and the problem is with the impeller...when it's hot it gets difficult to turn. With the head/impeller unit off the motor/magnet worked fine. Once the impeller cooled it spun freely. I thought these were godd to 200deg.

Take a 17/64 drill bit and widen the hole on the impeller. This is what Walter suggest on March. Luckily my one chugger works for boiling, my HLT one does not, but I never go over 180 on the HLT.

I did this to my chugger and it helped the 170° problem

Got a pic of exactly where to drill? I'm at work and cant picture in my mind where the hole is to make larger.

The center of the impeller, where it slides on the staff. You are just making the hole a little larger.

How did this work out for you guys? I've pumped 50-60 gallons through my pumps (HLT water at 170 and recirculating boiling wort) and had not had problems until this last batch. While moving the strike water to the MLT, the pump made a god-awful sound and stopped. It sounded like it had sand in the bearing or the bearing was shot. I sent Mike an E-mail and he got back to me instantly - asking me to take and send pics of the head.
Also, when I took the head apart (two days later), the o-ring stretched out pretty bad and I'll need a new one to put it back together.

The pump on the left was the problematic one.
