CSL/Poseidon Titanium pumps: rusty impellers?

[ejmeier]

Thinking about picking up a T2, but I remember back when I had my T4, after about 6 months of use (got it new) I notcied there was some rust forming on the underside of the impeller.

Has anyone ever noticed anything like this? It formed on the underside of the 'bell' part of the impeller. Maybe it is just titanium coated, and not completely 100% Ti?

I'm looking for this thing to go the long haul.

Ive got a T3 and a T4 running on my system now for over a year. I have noticed no rust on the impellers, just standard calcium type corrosion/buildup. Although, I did have problems with my T4 in that it kept leaking and letting in air around the impeller leading to major microbubbles. Now I have to silicon the seal and redo the silicon every time I clean it, PITA. Other than that I have no complaints with the pump, they run a bit hot but are extremely quiet.

HTH,

I guess I mis-stated my question a bit. The actual impeller part is made of plastic, but I was referring to the ROTOR beneath it. It is that bell shaped thing that is attached to the impeller.

I found this description from MarineDepot:

Poseidon is the world's quietest and only titanium centrifugal pumps. Poseidon Water Pumps feature sealless/leakproof designs and are made with noryl housings and impeller, titanium or stainless rotor and separating wall, ceramic bearing ball, carbon graphite bearing cap and EPDM o-ring.

Note the bold type (emphasis mine.)

Could it be possible that some people got a Stainless Steel rotor on a pump that was specifically promoted as being "Titanium" aka T1, T2, etc?

I have two T2s, one is about 5yrs old and the other is around 2 yrs old. I clean them about every 4-5 months, and I have never noticed any rust at all.

BTW -- the older pump is a CSL and the "newer" one is a Poseidon/Velocity -- whatever they are calling it.

Anybody else?

Took mine apart to clean it today, and this is what I found:

I have an email in to Laing to see about a replacement. I have only had this (T4) running since June.

I have not noticed any rust yet on mine however I seem to get a massive amount of calcium buildup. I now need to clean my T3 every 4 weeks and I'm unhappy about it. I don't know why this pump seems to have much more of a calcium buildup than any of my other pumps. I would attribute it to the heat except for the fact that my T4 doesn't seem to suffer from this.

So, I'm somewhat unhappy (I've had these for 2 years) but I don't have ANY rust.

I had the same problem when I used them. It looks like rust but it is calcium deposits. Soak it in vinegar overnight and it should scrub off. I had a similar thread with pics also.

 

[j0tca]

Although I'm rustless on mine, that picture above certanly looks like rust to me. I still think it's smart to try and soak it in some acid and scrub vigorously. It might just come off.

 

[ejmeier]

I don't think that its calcium buildup, but that would be great to hear if it just scrubs right off.

BTW - jpatrician, sorry I didn't read your post first here before replying to your PM. I didn't know that you went directly to Laing on this. Good luck.

Thanks ejmeir!
<P>
Tomzpc, I am pretty sure that this is not calcium buildup, if you look on the inside of the rotor, you can see calcium deposit. The area in question is actually recessed, and not a build up on the surface of the rotor. I will see if a good soaking in vinegar will remove it however.

UPDATE

UPDATE

I sent an email to both Laing & BlueLine. Blueline was the only one to reply, and they are replacing the entire pump!

 

[ejmeier]

good to hear.
