    Anyone know what kind of pump I have?

    I am having trouble getting the pump to prime so I think I need to replace the lid gasket? I've only had the house for over a year and I think the pump is at least 10+ years. On the lid cover it say Wet Instrument and Environmental Tech. I can't find anything when I google for it. Here is a picture. Thanks!

    Well, the label on the pump to the right says its a Centurion (Magnetek?) Look over on that label for serial numbers, etc.

    That is just the motor label. I have the same problem with my pumps...the motor labels are intact, but the pumps are incognito.

    Oh, so looking that up won't tell you anything? That's just not right! LOL Why does it have to be so hard...

    Re: Anyone know what kind of pump I have?

    I did try looking up the info but it is just the motor information. I now know what replacement for that I need! Unfortunately I need to know about the wet side.

    I just figured out I need a new cover as there is super small whole right in the middle of the cover. Only can see it when turning the pump on/off quickly a little spout of water comes out. I wonder if I could maybe just epoxy the center?????

    thanks for the responses thus far! Anymore info is much appreciated!!!!

    Re: Anyone know what kind of pump I have?

    Yeah, I had the same problem. The motor info was apparent but I had to look really hard to find pump info. If you haven't done so already, take a flashlight and look very closely all around the pump and you may find the answer.

    After scrutinizing mine, I finally found on the pump housing in very small letters: Sta-Rite.

    Re: Anyone know what kind of pump I have?

    Looks like a Premier pump, series 556N, should be a 6" lid o-ring. If it is a Premier pump, part # for o-ring is 33-489.
    Generic o-ring cross reference O-13 or an original Sta-Rite o-ring will work U9-46. Parts for this pump are not easy to come by. Lid and Clamp are obsolete. Hope this helps. Pump is old ! !

    Ditto! I see these every once in a while still. Probably not worth spending a lot of time with. A new pump will be much more efficient, quieter and easier to maintain (but probably not cheaper than keeping the one you already have!).

    I appreciate everyones responses and a big THANKS to Mike! I was able to do some searching with the info you provided and I think I found a few options for replacement covers. I do need a new pump but a new lid might be instore as I figure out the type of pump I should get (that may be a future thread after reading a bunch of existing threads).

    In the meantime, putting a bit of magic lube II in the center of the lid where the crack is makes the pump prime almost immediately. All the bubbles that use to be in the pot when the pump ran are almost non existant. This is my first pool and I'm learning tons thanks to TFP. Thanks everyone!!!

    Re: Anyone know what kind of pump I have?

    One more question as I'm feeling pretty dumb. The premier pump 556N looks close to my pump but there are a few things different so I went and measured. I measured 8" for the diameter of the lid on my pump, the listed dimensions for the premier pump is 6". Are the lids measurement the interior or the exterior measurement?? I just assumed outer diameter...

    I really need to get a new pump...without having to become a fluid engineer in the meantime...

    Thanks!

    Re: Anyone know what kind of pump I have?

    I believe its from the underneath side of lid. Basically, inside dimension of pump pot ( where basket goes ). My pleasure. Glad I could help.
