Pentair Challenger pump leaking

[atxdatta]

I have gone through a full teardown and replaced all the seals on my pentair challenger pump following the video by pentair (

) but unfortunately am seeing a significant leak that seems to be coming from shaft. Any thoughts on what might be causing it? I had to replace my impeller as it had broken so I thought I would use the oppertunity to replace all seals in the process, though it looks like it may not have been the best idea. All items used were pentair OEM ( 356199 for the repair kit)

Thanks for helping!

Did you use a lubricant when installing the shaft seal?

When installing the seal parts, using a lubricant can help. However, you want something that provides only transient lubricity. You can use a seal installation lubricant such as P-80 or US Sealube or dish soap. A Hayward video suggests vegetable oil.

When installing a pump shaft seal, it is good practice to use the proper lubricant to make installing the seal easy without creating adverse conditions for the seal. Ideally, the lubricant should provide good lubricity for only a short period of time and then wash away.

If a lubricant, such as a silicone or Teflon based lubricant, is used, the seal won't be as secure as it should be during operation of the pump. This is because the seals are rotating against each other creating some level of torque.

Also, the silicone or Teflon can have an adverse effect on the seal materials over time.

I used a soapy water to make it a bit lubricated, but no other lubricant for the shaft seal.
