The mechanical seal has two white side surface, one larger then other. What side is face-up on the seal plate? Also what end of the Shaft seal meet the seal plate and the Impeller. This is my first time changing the pool motor. Thank you.

Hi Rich, You would place white side of the shaft seal up inside of the seal plate. We have a great Video on How to Replace a Pool Pump Shaft Seal which goes into great detail on the topic.

No you would not need silicone glue to install this shaft seal. We have a guide with Video on How to Install a Shaft Seal which will walk you through the installation process.

I have a AO Smith pump (p/n: 7-165201-07) 2HP serial No. 317063M. The shaft seal is leaking...what parts do I need to fix it? thanks

We would need the front pump housing model that the motor bolts to in order to cross reference that seal for you.

Is there any physical difference between the Pentair Shaft Seal U109-93SS (Part #5056-08) and the Generic Shaft Seal PSR100 (Part #5250-100)? Do both seals use the same type/quality of materials (stainless steel, ceramic, plastic and rubber)? I don't care that one is made by Pentair and the other by US Seal, I'm more concerned with the quality of materials. I've had some problems with rusted seals and want to make sure either seal will function the same.

A  Answered on 6/8/2016 by InyoPools Product Specialist Scott W.

Yes sir, either seal will hold up the same. I don't know which Pentair pump you're referring to otherwise I would give you specifics, but if there's a saltwater shaft seal on the parts diagram for that pump I'd recommend purchasing that one if you're worried about rust.

Yes they do come in different sizes. Could you email us the make and model of your pump?
