My Pentair Whisperflo pump is making a loud screeching noise while running. What could be the problem?
Inside the pump is a set of bearings that help the components of the motor run smoothly. When they become clogged with dirt and debris or wear down, your pool pump may get very noisy or stop working altogether. This high pitched squealing you are hearing is fairly consistent with bearing failure.
t might be best to have the motor seperated from the pump housing and take it to your local pool outlet or motor shop. Installation of the bearings will be a breeze for them and make sure that no damage is done to the shaft of while the new bearings are being installed. At this time, they can also inspect the motor and make sure that there are no other problems with the pool motor.
Also, you should ALWAYS, ALWAYS, ALWAYS replace the shaft seal whenever you take the pool pump motor apart. This will ensure a positive seal for the motor and minimize the opportunity for leaks to occur.
Replacing the bearings in your pool motor:
1. Turn off power to your pool pump by unplugging it from the power source or by turning off the circuit breaker. 2 Remove the plumbing from the pump. Take off the unions on the suction and discharge side using a wrench. Loosen the pool pump from the fitting holding it to the ground and move it to a comfortable area to work in. 3 Remove the housing from the pool pump and separate it from the motor. Look at the owner's manual for your pump to see the specifics on how to remove the pool pump housing, since each model is different. Usually you will need to loosen a bolt with a socket wrench and loosen the metal band that holds it in place. 4 Remove the four bolts that hold the pump together. These are located on the hand bell of the frame. Remove the motor end bells. 5 Pull out the motor armature to expose the ball bearings. Insert your ball bearing puller to pull out the old ball bearings. Inspect them for damage. Replace the old ball bearings with new ones after greasing them with bearing grease, and reassemble the pump.
To be honest with you, I don't even let our technicians replace the bearings in the field anymore. It is a little difficult and really, how many people have a "ball bearing puller" laying around their house.
*Please note, this should ONLY be attempted if you are comfortable with the instructions and taking apart the pump, have the necessary parts and tools to make the repair, and are familiar with ensuring that everything is back together properly!
