DIY Red Dragon Pumps, gathering ideas.

[hahnmeister]

Oh wait... the 2905 (AKA powerjet 10,000) is actually rated at 137 watts normally (2905gph, 1.25" inlets and outlets) So I dont think that the wattage will be quite as low as the BK with air.

The Max-Flo 2400 might be a contender though; its inlets and outlets are the same size, and as long as the volute is of similar diameter, it might be a good alternative... its not designed to be the high-pressure of the 2905... so it may work better... or worse...lol.

Of course, I am still awaiting the info from Laguna on compatibility of old pumps with new impellers, and which of the new impellers may not contain brass.

The max flo 2400 has a larger outlet of 1.5 inches and a larger volute housing. That equates to more air! I have done lots of work with relieving volutes on different pumps to get more space. This pump has the same outlet size of the dart! I believe that makes it a winner..

Well, it does depend on the speed though. The 2905 MIGHT be a higher speed pump... and that could be its advantage over even a larger inlet/outlet and volute. Still... its worth a try...

Actually... lets gather some info while were at it...
Creetin, can you remove the volute and measure the interior diameter of the impeller chamber/well? Then we can compare this figure at least.

Are these things quiet? I was about to purchase a pair of 1260/62s, because I like quiet. How loud are they compared to 1260/62 series eheim? (I might start making one myself)

 

[Creetin]

I never heard a ehiem with a needlewheel or mesh modded, But the only thing i hear is air. The pump is dead silent!
I'll measure in a minute here, But the disk i made was the exact size of the fan i removed. It is around 2.5 inches and i believe the valute is over 3 inches more like 3.5 inches (I am guessing) because i thought i could have went way bigger than the 2.5 inch disk and mesh pad i am currently using.
I still haven't gotten to make the mesh pad bigger. That should if it works get me some more air.

Holy cow! You are still using the same 3 layers as before! We will definitely see more air if you go wider!!! I guarantee you will peg the 100 SCFH meter!

i really wanna know how many watts is the pump operating on. Also the carbon bearings how long they last with the air.

what if the mesh impeller was some how ducted. similar to the turbine

except instead of having the turbine blades, have mesh sanwiched in between the "top" and "bottom"

it will not work well , you can trim the top and the turbine balde with dremel and then to put on top the mesh .

I've been following this thread with interest and googling along with everyone looking for an interesting material to use for a mesh wheel. Needle wheels do a pretty good job of breaking the bubbles down but leave some room for improvement. People seem to have pretty good luck with various plastic meshes but that wound titanium would be even better.

Here's a thought...gutterguard is one of the materials that really started the whole evolution - what about the titanium equivelant of gutterguard?

Something like a short stack of mcmaster-carr part number 9259K11?

are you sure? it looks like klause may be using some sort of retaining ring on his mesh disk.

@Konadog...
the attachment of the metal wheels with a hole plate is tested. The perforated plate has thin needles, where the metal wheel is clean-pressed and tightened with a screw.

i think he was actually addressing my earlier question in this thread but, no matter.

 

[mavgi]

there is in the market S. Steel wire mesh (they use it for filter) and for vacuum pump( i also use it before on a vacuum pump on a membrane press ).


Knitted Wire Mesh it's the main company that produce this stuff and if i am not wrong i remember that there is also titanium mesh
available to (i saw it long time ago when i start with the mesh mod)

and you can see it here to :

Looks like we found the the match for the sicce pumps Michael. If we can get 100 SCFH out of a pump that is drawing in the 85 watt range, it will be hard to beat. Heck even at 100 watts it is awesome.

 

[mavgi]

Mike :

there is a new tech with the Sicce one...... and with the new tech the pump will pull twice then it pulls now :lol:

Here is what it mean (and this is if i am correct) :

2 sicce pump will pull about 120 SCFH = 3400 LPH this is with standard mesh on it ...... (if i will mod it i believe i will be around 4000LPH)

this also will be good for the regular Sicce pump that exist today and they will use about 70watt both , look good :lol:

Yep, The sicci pumps are for real, And thats not all they have done either. They (ATI)will aww the market with thier next release's. And someone told me they just steal thier info.

Back to the laguna. I will take the new 5000 impeller and use 5 layers of mesh and cut it to 1/4 to 3/8ths bigger than the disk.
And do the same with the 2905. The new one should be here today. The 5000 feels left out.

 

[dudedudedude]

Creetin,
Just out of curiosity, what are the new developments with sicce? Is there a thread out there that is talking about it?

 

[dudedudedude]

I dont know if this will end up being that relevant, but in ordering some Matala samples I found out that there are two versions. The older version which some poeple still sell is totally rigid, while the new stuff will keep its shape while being flexible. Do you see any advantage in using one type over the other?

 

[Creetin]

I am not of liberty to say, They will announce it when complete.
Sorry to tease you guys. I should have used a little more tact.
Anywho it will pretty cool to say the least.

I am not so certain the metal will be the best bet. How heavy is it?
Will it slow the rpm's down? Will it have start up issues? Ect
The metal needlewheeles is i am correct were having probs starting up on us voltage as the euro's have more torq with thier voltage. Hense the POM needlewheels RE has for the US.

 

[Creetin]

Still playing around with the same impellor config to see how much i could tweek the 3 layers. I knew i could get 10 more scfh.
Hell i think i could get to 120 scfh with the same size and layers. Just getting the sweet spot is the thing. I tweeked the huse around till it was 100 scfh. Now you guys can set the bar higher as i am just a newb at this.

 

[JCTewks]

creetin: so you have a daaper tank or barrel that you could use to test in to see how these perform with head pressure? i would be interested how much air they can spew with like 36-48" of head. if they can hang at those pressures, i do believe this will make the new ORCA NW darts pretty useless in my book. you're getting as much air at prob the same watts or less on your first try of the mod. Congrats!! i'm curious as to how much better 5-6 layers and bigger diameter will do....i bet you'll need a bigger flowmeter LOL
