There is a problem, however, when poor drainage causes standing water from storms to linger around the motor. Lets dive in. Pulled out pump and noticed a nick in one of the impeller bladed. Over time, this device can become worn and loose, which can cause noise. In your September 2016 article What Happens to Power and Efficiency when a Pump Wears Out, which I really enjoyed, you mention that the data on power can tell the difference between the types of internal wearfor example, if the wear ring clearances have worn out or if the impeller itself is deteriorating (as might be the case with highly abrasive pumpage or corrosive chemicals). I have thought about this and believe that wear that affects the impeller only (and not wear ring clearances or other leak paths) would result in: with the decreased pump power being the difference in comparison to the results shown in your paper. Motors and impellers have two total horsepower scales, uprate and full rate. I think it's a wiring/voltage problem, beyond the pump. Now youll be able to use the screwdriver, coat hanger, or even needle nose pliers to remove the debris from the impeller. If that checks out, I'd confirm the motor and impeller you are using are matched correctly. PumpWorks Understands Wear Rings At PumpWorks, we are passionate about getting the most from every pump.

A good rule of thumb is to run the pump for at least 6 to 8 hours a day, approximately one-half hour before dusk, in order to filter out debris, bacteria, and particles that have accumulated throughout the day. And if your impeller was clogged, you would not have good flow initially. To explain further, if the impeller is completely plugged, or worn to nothing, there would be zero flow and zero pressure generation, yet there would be still some power read on the electric meter because the pump still consumes power on rubs of the bearings, seals and other mechanical losses. So, in that example, the power would be small, but still not zero. And it pretty much looked like the parts I was replacing. Ive thought about this some more, and I have one more question. Request Service Online. What causes it? Unscrew the single screw that hold the capacitor in place and push it out of the way.
