Whenever you replace your motor, we highly recommend replacing your pump shaft seal as well. Not only does it protect the motor from water damage, but it also secures your one year warranty on the new motor. It’s a win-win scenario.
But, how do you find the correct seal for your pump? Are they all the same? Should you replace other seals at the same time? Let’s dig a little deeper.
Important Information Needed For Your Seal
Make and Model of Your Pump
Okay, I can admit that it can be a little confusing choosing the correct seals for your pump. From our experience, the biggest confusion stems from the information pool owners actually need to get the correct parts. To order the correct seal for your pump, ideally, you need the make and model of your pool pump. This information is typically located on the pump housing, opposite of the motor. This information has its own separate label.
Unfortunately, the motor information cannot determine which seals you need. Like the shaft seal, the motor is simply a single component of your pump. It makes sense, though, to think the motor information is helpful considering half of the pump seal goes on the motor shaft. However, in this situation, it isn’t.
Here are examples of where you can find your pump’s model number
I Cannot Read or Find My Pump Label
If you cannot locate or read your pump label, don’t fret. There are other ways for pool owners to identify their pump without the pump label. The good thing about the majority of pool pump parts is that they are very specific.
For example, Hayward doesn’t use the same housing for the Super Pump and the Super II. This makes it easier to cross-reference when determining which pump parts you need.
If you do not have access to the pump label for whatever reason, your next goal is to locate a part number on a single piece of your pool pump.
Without Uninstalling Your Pump
Pump Housing
Luckily for us, there are a few ways to identify your pump without un-installing it. If you cannot read or locate the pump information, look for the part number engraved on the pump housing. Below are examples of what they look like and where you might find them.
Pump Lid
If you’re looking for another part number, the strainer lid is the easiest place to start looking. The strainer lid sits on top of the strainer basket in the pump housing. Below are examples of strainer lids and of places you might find the part number.
Here’s another example. This is the lid for the Starite Dyna-Glas and Dyna-Max pumps
Here’s one last example of a strainer lid. This one belongs to the Hayward Max-Flo pump.
Pump Strainer Basket
Directly under the strainer lid is the strainer basket. If you cannot locate a part number on the lid, your best bet is to look at the strainer basket next.
Uninstalling Your Pump
If you’re unable to find a part number on the pump housing, the strainer lid, or the strainer basket, unfortunately, the next step is to un-install your pump.
You can find part numbers on the impeller and diffuser in your pump. However, in order to reach both parts, you will have to remove the motor from the pump housing. If you need help removing the motor from your pump housing, I recommend watching our how-to video on how to replace your motor.
Impeller
Once you’ve safely removed the impeller, inspect both sides for the part number. The impeller is very specific to the model of the pump and therefore can be a very useful tool to identify the specs of the pump. This is also a great opportunity to inspect the condition of your impeller.
Some manufacturers handwrite their part numbers on the impeller.
Diffuser
Most of our customers have the most luck finding part numbers on the strainer lid or the impeller. The diffuser, right behind the impeller, also contains a part number. Because of the odd shape of the diffuser, the part numbers are more obscure and we recommend having a magnifying glass handy.
Things to Remember
Pump seals and gaskets are small but they’re kind of a big deal. O-rings, gaskets, and seals protect your pool parts from water damage. This is why we always recommend replacing your pump shaft seal whenever you replace your pump motor.
Whenever you need to replace your pump seal, make sure you have the make and model number of the pump handy. Remember, you cannot determine which pump seal you’ve got from the information on the motor label. If you cannot read or locate the original pump label with the model information on it, locate a part number off of the pump. Typically, you can find part numbers on the pump’s housing, strainer lid, strainer basket, impeller, and diffuser,
If for whatever reason you are running into issues locating a model or part number, give us a call. We’d be more than happy to help you cross-reference any parts and locate the correct seals for your pump.
I have a Doheny’s 1.5 hp model 90950 inground vs pool pump and need a shaft seal. I can’t find any part numbers on the pump housing. The Doheny’s seal part number is 176578; however, that part is on back order. Are there any other brands that fit this pump?
HELP!!! Can you please help me find a shaft seal for a pump. No one sems to be able to do so. It’s a Century UB2984 pump installed into an older Pentair housing (the kind with the band clamp) . The impeller PN is C105-137P.
The C105-137P cross references to an obsolete impeller for the Sta-Rite Dura-Glas / Max E Glas pool pump. Does your pump resemble the one shown on the link?
Hello can you help me find the shaft seal for my pentair pump housing? Here are my numbers, from top to bottom.
P/N 342351
PMP PFI P1 1HP ALMO
Serial No. 03092780800381
The necessary gasket kit for the Pentair / Pac Fab Pinnacle is the GOKIT24.
I am trying to find the correct pump shaft seals for a Century 56Y B2854 pump, thanks.
The gaskets are matched to the pump housing rather than the motor. We will need the model number of the pump and/or a picture of the pump housing.
I want a 1/2 shaft seal for a pool pump
What is the make and model of the pool pump?
I need a impeller for a Intex SF70110-2, can’t seem to find one???
I have a new Pentair C1-271P1 Diffuser and am attaching the Neptune Variable Speed THP 1.65 HP Square flange – What Shaft Seal would I need?
The C1-271P diffuser is for a Sta-Rite Pool pump. I’m not familiar with a Neptune VS, which could be a private label. Does your pump resemble either of the pumps shown on the link below:
Sta-Rite Max-E-Pro Pump
Sta-Rite Dura-Glas II and Max-E-Glas II
Looking for a shaft seal for Sunrunner Pump. I don’t have the model number. The number on the pump plate that the seal goes in is PPGF30 the number on the impeller is PPOGF20.
I think I may have found it. The SunRunner may have been a private-label version of the Speck Badu SuperPro 48. The shaft seal for it is the Mechanical Seal 5/8″ – 2921606204
I am looking for a shaft seal kit for a century centurion pump. Number on the impeller is SP-1605-c
The impeller number fits a Super Pump most likely. The most common seal used for the Hayward Super Pump is the PS-201
Looking for a pump seal for a pump and housing that absolutely has no markings. The impeller number = PPO-GF20. (Internet says is Pentair,IDK)
Under the strainer cap ring = PAG-GF20.
The O.d. Of the impeller end of the seal is 35mm diameter. The housing side seal diameter is 45mm diameter. The stack or overall width is 26mm.
Are you sure this is a pool pump? The PAG-GF20 cross-references to a double pole breaker, and the PPO-GF20 comes back to a vague description of a “water pump,” which could be irrigation, well, or other auxiliary pump types. We would only have schematics and resources to find pool pump parts.
I installed a brand new pump / motor assembly last year. This year, I had to remove it to replace a broken drain plug (pool openers broke it and tried to glue it on…yikes).
Now I have it reinstalled, everything is working great but the pump is now leaking. As mentioned, this is a brand new pump…do I need to replace the shaft seal already???
What seal do I need for 03185P found this on top of the filter lid.
The shaft seal is a part of the pump, not the filter. We would need to ID the pump model to find its parts. That part number looks like it is a Bestway brand system; a company we do not carry parts for.
Im looking for a shaft seal for a intex pump model sf80110-2
That is an Intex brand pump/filter system. We do not carry any schematics for them. I’d contact Intex directly or see if the company you bought it from can provide you with part numbers.
looking for the correct shaft seal for SP2805X7A
The Hayward MaxFlo uses the GOKIT1 gasket kit if you want to replaces all the seals. For just the shaft seal, a traditional chlorine pool needs the 5110-11, a saltwater pool uses the 5250-235
Hi, we have an Intex SF70110 and need to replace the shaft seal. The impeller part # is 28647. Any assistance for the correct shaft seal kit size would be greatly appreciated .
I did a quick search of “SF70110 parts’ in google, and quite a few results came up. The second result was the parts manual for the pump and filter. It looks like the parts from the impeller all the way to the motor, which includes the shaft seal, are not sold as individual pieces. You might want to contact Intex or the dealer you purchased the filter system from to see if they can source parts. Because we are not an Intex dealer, my research resources are limited.
I am trying to find a shaft seal kit for an above ground pool
pump model cs20110-m
diffuser # 28647-4
I have an intex pool with the combination sand/salt 2650 gph up to 15,000 gal
thank you for any help you could give
Unfortunately, we do not carry parts for Intex pumps. Also, most of the manuals and parts breakdowns I have seen of Intex systems over there years, the shaft seal s not a piece sold by itself. Intex likes to bundle their motor and drive train parts (seal plate impeller and shaft seal) together rather than parting them out.

Think it’s a Waterway model.
That model numbers comes back to a Waterway Hi-Flo & Hi-Flo II . The Hi-Flo does not have a gasket kit bu the individual gaskets can be picked off the aforelinked parts diagram
I’m trying to find a shaft seal kit for a Century 1081 with part number 0-173840-23 and Frame Number N56CZ. Any thoughts? Cheers. MattJ
Never Mind – That’s the motor. The pump is the old style Polaris BP4-60! I found the part I needed.
For future reference of anyone looking for Polaris booster pump seals.

Hello Matt,
Is it before 2011 style? I have exactly same and try to check for the impeller but could not find figure out it is old or new style.
Thanks in advance
Loan
Look at the front face of the volute. if your pump’s volute looks like this PB460 – P5, it is a 1994 – 2011 model. if your volute looks like this Volute With Drain Plug and O-ring- R0536300, it is 2011 to present.
I need the deal impeller for the exact motor. What did you find and where? Thanks!!
The B625 is used on the different eras of the PB460. Do you know when your pump was installed?

I am trying to find a shaft seal kit for an Intex sand filter SF60110. The motor part number is 11807EG. The only part number I can find on the impellor or plate is >PPE<. Thanks!
The parts diagrams I found did not include a part number for a shaft seal. It appears the motor and seal plate are considered one piece. We do not sell these Intex parts, so you might want to go directly to Intex or an online dealer of theirs.
Did you find your shaft seal? I Had mine go recently and think I’ve found a replacement for it. Waiting on a couple from China. It appears to be a metric seal.
Google “301-12“
Were you able to find the necessary seal?
will a PS-201 pump seal fit impeller #35-5369?
If that impeller is installed in a Challenger pump, no it will not. If that impeller is on anything else, I cannot tell you for certain. The pump housing’s make and model is the information most necessary to find gasket and seal parts. Do you have that info?
Which is the right seal for the impeller. Sp3021-c
Normally, we would need to model number from the pump housing; but luckily, this impeller is used in several pumps that use the same shaft seal. You need either a Pump Shaft Seal 3/4″ PS-201 or the Pump Seal 201, Extra Heavy Duty PS3868 (Saltwater Pools) – PS-3868
I could not find any numbers on my Pump. The seal has an inside diameter of 5/8 in.
the total length with the seal and seat is 1 inch without the seat it is 6/8 ”
the seat with the rubber ring around it is 17/16 diameter and the seat itself ( the white ceramic ) is 1 inch diameter.

Finding a shaft seal by measurements is not a real efficient way of doing it. Did you look on the impeller, diffuser, or seal plate for any part numbers?
I have never seen a pump that has zero identification numbers on any of the parts.
I will look again.
