SOURCE: I have a challenger pool pump that has a very high

The motor bearings are probably starting to fail. If you winterize the pool I would take the motor portion off the pump and have a local electric motor repair shop look at it. A simple bearing change and new pump seal would run $50 or less at most places. If not, shock the pool and run the pump overnight to balance the water and then pull the motor for the repair. It will probably only take a day or so for it to be completed.

could be its has air getting in when its pumping or the motor bearings are worn out or just dryed out it could even be a partly blocked inlet filter causing this pump to whine,
try looking for inlet pipe air leaks and blocked filters
or some thing resting on the pump impeller

SOURCE: Proline Pump 8D-10-1n11CB. This is for a pool and is leaking from the shaft to the motor

The pump seal is bad on the unit. This requires disassemble of the pump unit. Remove power to the unit, dissasemble pump housing, remove the impeller from the shaft of the motor by removing the allen screw with an allen wrench. Seperate pump housing from motor remove the old seal replace seal. Lube motor shaft with a little clean oil or wd40 to facilitate easy install thru new seal,reassemble in reverse.

SOURCE: our dynamo CA04-26 pool pump is making a whining

The bearings are likely failing and they are not open to allow for re-lubrication. You can replace them yourself or take the motor to a local electric motor repair shop to have it done for you. A shop will probably cost about $40 to $50 for parts and labor. You should also replace the seal at the same time. The cost for the seal is under $10 and the labor shouldn't change.

most likely the bearings are starting to go.
