DIY "Stream" Style Pump

[dhnguyen]

That's old news (the backspinning nub). What I can't believe is how much this guy is charging for it @ $59.99 with just the impeller and guard. Crazy...

What would be the point of spending THAT much when you can buy a brand new SEIO for so much less?

a rio seio, haha. you would put a rio in your tank?

the thing I like about this one is it looks nice. to me performance counts for about 25%, style 25%. and the last half would be price and power consumption. realisticly if its going in my display tank it beter not look cheesy. if it was a frag tank I wouln't care what it looked like.

im not selling these so I can't speak for the price, but I would love it if these where half price, but what can you do. labor costs money. if these where mass produced im sure you could save a lot in production costs.

after all is said and done, would I buy another? yup.

btw, where can you get a seio cheaper? marine depo has these:
TA3713 Taam Seio Super Flow Pump M820 $52.95
TA3715 Taam Seio Super Flow Pump M1100 $62.95
TA3717 Taam Seio Super Flow Pump M1500 $69.95 <------

and how about tunze? Tunze Turbelle® Stream 6000 $259.96 <---holy cow

[dhnguyen]

Well I WOULD put a SEIO in my tank. I think it's unfair to compare the SEIO against the Rio as these are not he same pumps at all. Even the newer Rio's design have changed as Taam is no longer using oil but rather epoxy resin in the motor now.

But as far as pricing goes. You just answered it.

TA3713 Taam Seio Super Flow Pump M820 $52.95

This guy's maxi-mod - $59.99 (and that is without the MJ powerhead even).

The one thing I do like about these mods is that the size. The SEIO is HUGE and can be quite unsightly whereas this one can be made quite small (not much larger than the stock MJ design)

My 0.02 for what it's worth.

I made mine for about $4, here is my 2" with 1-3/4 prop on Maxijet 600, beat out Seio 1100 easily, scroll down to bottom to view. 2" Maxijet Mod

I noticed your mod earlyer in this thread. its interesting that you can use the original inpeller and change the flow patterns.

[dhnguyen]

Very nice work quangtam7. How did you get the cross brace to look like that?

Yea, and it needs maintenance (regular cleaning) to work. Otherwise the impellor will spin in same place no matter which way it's turning after a period of time. No slidey - no wacky into something.

So faced with: fiddle-as-necessary or fiddle-on-a-schedule - well guess which option I choose. Personal opinion.

I LOVE the personal expression in quangtam7's thread. (Seeing the design genius - can he be anything but Italian? I’m not worthy.)

I could do that, if I wanted to. But I make mine ugly - so that your average Joe can say "Crap I can do better than that" and digs out his hot glue gun to prove it.

[dhnguyen]

Well if the name Quangtam7 is indicative of who he is I'd say he's Vietnamese (or at least Asian) and not Italian

Agreed though, the guy can work magic with a PVC pipe and tile saw.

But what the hell do I know LOL

These are all great and creative designs!!

Question:
Did anyone on ReefCentral get the patent for this kit available for sale?

http://www.reefdom.com/proddetail.asp?prod=MAXIMODKITWPUMP&cat=106

[dhnguyen]

There is no patent for this mod as far as I know. Maybe someone else can chime in but as far as I know it's kinda a free for all right now.

I did the mod a couple days ago, using an NOS-prop out of my parts box, it was noisy, then i came back across to this post, and noticed it had never been addressed by any of you other rc boaters out there.

so after a minute or two of cleaning off my work bench i found my trusty ballancer http://www2.towerhobbies.com/cgi-bin...?&I=LXDS11&P=0

a few minutes with my file and the noise is gone, the prop is sharper, and it pushes a ton of water don't know why i didn't do that in the first place, anytime i get a new prop for my boats i ballance it first. but anyways, i do know that some hobby shops will balance props for a small fee.

is there a link to a place where this thread is condensed into a step-by-step detailed instructions manual? Just thought I would ask before reading all that.

how many of these mods should i use for a 180 gal tank(6ft by 2ft)? the ph we have here are rated for 2200lph for 25 watts. maybe ithose can throw more water than mjs?

[skierguy]

Is it possible to balance a prop if it has been drilled slightly off center? It is nearly impossible to drill the props out perfectly centered. *mine are drilled close but not perfect. I do notice a slight shimmy when the props are running. Can this be fixed by having the props balanced?

[dhnguyen]

Yes you can balance the prop. You'll need a propeller balancer to do that though. Check Towerhobbies.com

2200lph is about 580gph. That's a lot of power for a 25W powerhead. What kind of powerhead/pump is this? And yes I believe they would be stronger than Maxijets.

To utilize that power though, you would need to use larger propellers (1.75" and larger)

I'm thinking 2 of these with the larger propellers on each end of the tank would be sufficient. If you want CRAZY flow use 4.
