Impellers, vary. You can't put any impeller on a motor!
Things to take into consideration for proper water movement / hydraulics, is the different parts of the volute: where the tide housed. You have the:
The impeller also had to match the HP!If impeller is oversized, the motor will be over worked! If impeller is under sized, then the motor will work effortlessly, but is a waste, because it should at least be at capacity.Even if within the same manufacturer, impellers vary widely.So, find the correct impeller and use it.
It sounds like you have a suction leak or a clogged impeller. A quick way to check the impeller is to fill the pump pot (where the basket is) with water, then start the pump with the lid OFF. The water should be sucked down into the pump immediately. Turn the pump off. If it took more than about half a second for the water to disappear you need to open the pump and clear the debris from the impeller. Otherwise any leak from the skimmer to the pump will cause the problem. Make sure your pump lid o-ring is lubricated.
Have you opened up the wet end? If you have pine trees near you, it is probably a blocked impeller and needs to be cleaned. If this is not the case, is the pump basket full of water or air?
If it is full of water, it is either the impeller, or the motor bearing.
if it is full of air, it is an o-ring or shaft seal. more likely the shaft seal. Always check the impeller first.
ON A HAYWARD #1 BROKEN IMPELLER OR PLUGGED ,#2 SHAFT SEAL #3 LID SEAL #4 TANK CRACKED.. LOOK FOR YOUR LOCAL POOL PUMP MOTOR REPAIR GUY USE YOUR ZIP IN YOUR SEARCH .. YOU WANT THE IMPELLER WITH THE BRASS SHAFT ! ASK FOR IT HECK DEMAND IT !... YOURS IS PLASTIC = PLASTIC THREADS (JUNK) .IF'N I WAS ANY HELP VOTE FOR ME ...THANKS.. JAY
On the big lock ring there is a small clip that you pull out away from the ring then turn out of the way. It is just a peg to stop the ring from turning, with that done from the back of the pump loosten the ring in a counter clockwise direction. With the ring clear start the pump for just a second a couple of times till the water pressure pops the pump in two. Once that is done I beleve it has five screws holding the difuser on, pull that and on most models their is a center screw on the impeller. This screw is a left hand thread so turn it clockwise to loosten it. Then insert something flat and strong in a vain of the impeller on the left side and give it a sharp hit to start the impeller spinning off. If need be spin the rest of the way off and your at the seal. Rember when putting this back together Hand tight only on the impeller and use a teflon or silicone base lube not petroleium jelly.
Did you prime the pump? To prime: Before turning pump on, unscrew plug cap from top of pump (usually on pump impeller housing,) and with a pitcher or garden hose, fill pump full of water, and replace plug. Then turn pump on and see if problem is solved. If leaking: Are all fittings tight, O-rings and seals new, and is there any pipe thread tape on all threads w/o seals?
Sidewinder, sounds like it's leaking from the pump gasket or the water seal assy on the impeller. Check the locking ring to the pump housing and see if you can increse the pressure to the tub. Also check the tightness of the motor fan assy. to the impeller assy. tighten if necessary. Pump gasket part number is 912529. Impeller seal part number is 903494. Catriver..post back.
