How to Replace The Hayward Super Pump Impeller
Hi my name is Joseph I want to share with you how I change the impeller on the Hayward super pump. You’re going to need some tools before you can remove the impeller from the pump. You’re going to need a 9/16 open end wrench, you’re also the need a bucket of water to re-prime the pump. The first thing I always do is unplug the pump cord pigtail from the electric loud. I guess make sure the time is off just for safety reasons. Now I will remove one or both of the drain plugs so I can drain the wet end of the Hayward super pump.
Once all the water has drained from the pump housing I will take my 9/16 open end wrench and start to loosen each one of the four bolts on the back side of the pump housing. Now you want to make sure that you remove all for the bolts otherwise you will not be able to disconnect the wet end of the super pump from the electrical motor. Once you have the four bolts remove the wet end and the electrical motor on the Hayward super pump will separate into two different pieces.
Now that the wet end and electric motor or two pieces you will need to remove the diffuser. To remove the diffuser all you have to do is pull on the diffuser and it will separate from the pump seal housing. Once the diffuser is removed you will able to see the impeller. What you want to do now is take a strap wrench and attach it the impeller. You now will want to remove the rear cover of the motor. Once you remove the rear cover of the motor you will see the motor shaft. You want to hold the motor shaft with a pair of pliers or an open end wrench, so when you turn the impeller the electrical motor shaft will not spin and the impeller will loosen.
To remove the pump impeller take your strap wrench and turn it counterclockwise while holding the motor shaft with your pliers open end wrench and then continue to spin the impeller counterclockwise until it is fully removed from the motor shaft. When you install your new Hayward super pump impeller you always want to make sure that you replace the pump seal. Failure to replace the pump seal will only cause you problems down the road when the mechanical seal starts to leak, causing you to have to take the pump apart again just to replace the seal that you should never place while you were replacing the impeller.
To reinstall the impeller you will want to make sure that you replace the seal on the impeller itself and also seal see that is located inside the seal housing. Once you have replaced the seal you want to spin the impeller back onto the pump shaft counterclockwise, when the impeller starts to get tight you want to hold the pump shaft with your pliers are open end wrench into the impeller is fully tight. After the impeller is tight you will want to replace the diffuser I reattaching it to the seal housing. You now can put the wet end and electrical motor back together. Once you tighten the four bolts that holds the wet end and the pump housing together, you will want to replace your drain plug, fill your pump housing with water, and then restart your filter system in your pump should now work.
We have a suction problem with a Hayward Super Pump. It will barely and sometimes not all the time sweep dirt off the pool floor. It is about 5 years old and used to work fine. Can the impeller wear out?
What can I do to troubleshoot it?
The impeller could wear out but chances are its just clogged and just needs to be cleaned. You can do so by removing the Hayward Super Pump Housing and then you will need to pull off the pump diffuser and then you can clean the impeller out with a small screwdriver or a small piece of wire like a close hanger. Sometimes rocks, long grass and other stuff slips though a skimmer basket with a small crack etc and over time the impeller will gather a bunch of debris.
Hope this helps and let me know if you have any more questions.
