Does it met for ITT Marlow pump SDA75?

The number you provided does not allow me to pull anything up. If you are looking to replace the shaft seal on your pump please attach a picture of your pump so I can identify what you have.

will this fit the shaft for the ao smith catb227 threaded shaft I am replacing on a argonaut pump?

Yes, that would be the correct shaft seal for your Argonaut.

The shaft is leaking on my above ground pump. The parts tag on the pump shows the following: A.O. Smith HP: 1.0 SPL part # 7-187609-21, serial number BW6-22, SP W48Y. 60HZ, RPM 3450. The wet end has the following tag: Jacuzzi model S1kG9-3, order no. 94027976NB0X, Date 15 Jun 01. I did not install the pool so I do not have any information about it. What shaft seal part should I purchase?

Hi, The Jacuzzi S1KG9-3 uses a Pump Seal 200 (PSR200).

How to get pump separated from motor, I have a motor model s48874a03 and pump model jwpas5f-2a4

While this video and instructions are not for your exact pump, it still covers all the steps needed to remove a motor. Please click "How to Replace the Motor on Your Pool Pump" 

?     Asked on 6/10/2015 by brian

I bought this along with a motor. I have setup watching your diff videos. It is a JWPA Sta-Rite pump. After hooking everything up and turning it on, there is water coming from the backside of the impeller so the seal is failing. I did have a VERY hard time getting the seal onto the impeller and I'm not sure the spring is actually able to move properly. Should I lubricate the impeller to help slide on the seal, and if so, with what (not the seal itself, but the impeller to help slide on).

A     Answered on 6/16/2015 by Lennox H.

Brian, Lubricating the shaft/inside of the impeller with a silicone lubricant where the shaft seal goes will make it easier to install the seal. You may need to install a new shaft seal since its leaking.

Which side goes where when I replace this 201 shaft seal?

A     Answered on 9/15/2014 by Patrick P.

When replacing this 201 shaft seal as well as others you need to put the spring side on or against the impeller with the dark ceramic side out and then the other half of the seal inside the pump seal plate with the white ceramic side facing out. Please be advised not to touch, wet, or dirty any of the ceramic parts for it very well may compromise the seal.

 (5 out of 5 stars)  Just the part I needed to stop the leak!

from Galesburg, IL ()

Pros: Super fast shipping and lowest prices

Cons: None!

I replaced this seal on my pump last week and it stopped the slow drip leak problem I was having. Inyo shipped it out to me very quickly and I had it on my doorstep within 3 days and at a great price too (along with free shipping)! Will definately buy parts from them again.

 (4 out of 5 stars)  Affordable Sealing Solution

from Hamilton, MS ()

Pros: Affordability

Cons: Rotating Element Material

This mechanical seal is not bad for the price, but working in the pump and valve industry myself, i would recomend a better face material for the rotating element other than the phenolic face, such as tungtson carbide. The staionary element (ceramic) is fine, as long as you do not experience extreme temperature changes, this will result in cracking the seal face.

 (5 out of 5 stars)  Replacing seals is a NO-BRAINER

from Rosemount, MN ()

I am a penny pincher, I could not find a better price than right here at inyopools.com I am very happy I replaced the seals while I had the motor apart. I didn't realize how badly work my old seals were until I had new ones to compare with. I also replaced the impeller which I think really helped circulation. I had more water pressure with a new, lower HP motor, than with the old higher HP motor probably partly due to the new impeller.
