Perhaps I should have been more clear, The flimsy construction I am
referring to is the impeller cover and output "cap" (the part bolted down
with 4 screws)Thinest most brittle piece of plastic..Doesn't take much
pressure to crack it!

The loudness part varies, but 2 of the 4 mag's I had started making
grinding/rattling sounds within 1 year.

i guess we are talking about two different "mag" pumps, i have several and
they are quite as church mouses and are solid built and not what i call
"cheap" on price either.

The T3's put out allot of heat and I KNOW you'll end up needing a
chiller.
The Quiet ones are not Quiet and overheat way to easy (I am referring to
the
new and old models). I'd never do a mag drive..noisy, and some of the
flimsiest housing I've ever seen, however they are cheap..but you get
what
you pay for. I personally would try an Eheim hobby pump maybe the 1261
or
1262. Unfortunately the Eheim pumps are not cheap...mine set me back a
few
hundred bucks. Just my 2 cents.

Hey everybody, thanks for reading.

I am having a very difficult time deciding on a pump for my return
line.
I
have considered a GRI (Gorman Rupp) 510 (can't find much feedback on
these),
Custom Sealife velocity T3 (worry about heat exchange with this one)
and
a
Lifegard Quiet One. I could really use some input on this decision.
Please
let me know what you are using good or bad. If there is a pump I'm
missing
let me know about it.

My main qualities I'm looking for are quietness, heat exchange and
durability.

I'm looking for around 600-800 gph at 4.5' head.

Thanks so much,

Ken
