Question about Pentair 1 hp WhisperFlo InGround Pool Pump WFE24 ()

1 Answer

I have a whisperflo. I've ran the motor without water and it's quiet. Add water and it makes a pretty good racket (not a bearing whine). I've even tested without my filters to eliminate head pressure) I'm not getting air. I've replaced all of the o-rings (just 2 of them, 1 shape of housing and 1 on the front of the (diffuser?? , about the size of a softball)) I've pull front half of the impeller apart and pulled the cover off to clean. It's immaculate. Here's where I'm impeller has a screw in the shaft that I've removed (left handed). does this hold the impeller on, or is the impeller itself also screwed onto the shaft?

Yes the impeller is screwed on right handed normal thread. *** Info below pasted form one of my other posts *** You need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, (usually 9/16") or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. (you already did this.) It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it.

A very annoying whine when riding until you hit 110k plus

Could be several things, but lets check the less exspensive solutions first.

Chain/Belt guard bolts loose and scrapping tire or belt.

If shaft drive, check/add gear oil.

Get a piece of wood and put it against the motor and the other end to your ear.
Now put it against the transmission
Now put it on the clutch cover
Listen to see where the sound is more prominent(noticeable).
If motor you may be hearing a stiff timing chain, check/change oil & filter first, then listen again
if tranny, you may need to change your oil, if you hear the gaers whining. good clean oil will quiet a noises tranny.

Clanks , clucks, rattles, are not good noises
a whining noise could be something simple to worn out bearings.

Check to make sure that nothing is rubbing first,(misplaced saddlebag,loosened guard)

Listen with a stethescope or piece of wood if the noise is hard to locate.

My Pentair WF-26 1.5 HP just started emitting a loud "whine" detectable above the regular pump noise. Looking through the window into the debris basket the water also looks more frothy than...

The loud "whine" you hear, does it sound like its a metal kind of "whine"? There are a couple of things it could be. Your impellar may have debris caught in it and to properly check and clean the impellar you will need to open up the pump and remove the diffuser and check/clean as needed. You can sometimes remove the basket and try to feel your way with a couple of fingers to the impellar but your only able to reach 10% of it. Whisperflo is an outstanding pump but very notorious for debris getting stuck in the impellar and the impellar breaking easily because it is plastic. If you have ran the pump without prime/no circulation you can easily have caused heat damage to the impellar. The other thing to check is the motor. Although it is only 2 1/2 years old the motor still could be going out. The bearings are the top noise makers when a motor is going bad. You will still have normal suction/circulation it will just be really loud when the motor runs each day.

I hope this helped. Please don't hesitate to submit any further questions you may have. I would be glad to help.

More than likly it's a square flange motor. If the noise is just starting when you take the pump apart you can check the impeller for problems but the most likley is a bearing going bad from a seal leak. If you remove the wires and take the motor with the back half of the pump to a pool store they can diagnose it for you and do the nessary repairs at the shop. Usually they will do this for a small bench fee or for just the price of the nessary parts.

My Whisperflo Pool Pump is making a racket. Is

Stick a large screw driver on the motor in the area of the bearings and on the pump housing ... stick the handle to your ear (notice I said to your ear ... not IN your ear) Listen. Often you can determine the source of the noise in this manner.

My money is on the impeller. You will need to replace the seals when you disassemble the pump motor from the pump housing. I found a dime in the impeller recently made a racket until the impeller wore down in that area.

Motor noise coming from hp designjet 120 nr

The fan is probably filled with dust. This can throw the balance off and make vibrations or cause resistance which can make a humm, not necessarily a bearing, not sure if the fan even has bearings. Anyway, the intermittent noise can be that the fans only run when the printer is hot. Find where the noise is coming from clean off the blades and components with a damp rag, blow around or lubricate the center of the fan, and replace it in the printer. Should fix it.
