jose Posted February 3, 2010 Report Share Posted February 3, 2010 I have a Pentair Whisper Flo 2HP pump that is leaking between the motor and main skimmer housing whete it bolts together. I would like to open it up and see what is actually damaged so I can get the parts. I am an avid DIY but need to know the basics and the gotchas I should watch out for in opening up the pump: 1. Turn power off to breaker 2. Loosen bolts between motor housing and main housing 3. Pull it apart Anything else? When I replace the seal, any lubricant such as sillicone? etc etc etc Thanks Jose Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted February 3, 2010 Report Share Posted February 3, 2010 Make sure you replace the shaft seal, not just the housing seal/gasket. 4. Take diffuser off. 5. remove impeller (hold motor shaft). 6. replace shaft seal. Quote Link to comment Share on other sites More sharing options...
MKuz14 Posted March 3, 2010 Report Share Posted March 3, 2010 When you remove your defuser and use your 1/2 open end wrench to hold the shaft from the back and spin of your impeller off. make sure you do not touch your new seal with your hands, use a paper towel or rubber gloves. New pump seals are just like expensive light bulbs, your finger grease can degrade the life expectancy. I believe that pump takes a PS-1000 pump seal or you can get an Aladdin pump seal, part number AS-1000 which is just as good as the pentair one. I recommend using a short piece of 1.25 PVC pipe to set the seal to motor side. Just tape the pipe lightly with a hammer and that seal should set in there just fine.
