DIY Spindle Wheel Impeller

[Cedric]

First of all, I like to thank a very important person, thc. Without him, this project would not have materialise. Thanks bro!

more pix . . .

Close up, sorry for the blur pic, no mini tripod lah!

Impeller disassembled.

[thc]

Wow, look very good lei.....very impressive ...ehhh do you have test run pic??

[Cedric]

Well, the pics I took are not reflective of the actual situation. My sump is very cramp and I cannot get a good shot. The pics doesn't say anything.

What can I say is the bubbles seems smaller, but the noise is louder!

Neat man...

[ah^siao]

where u got those parts from? wad did u use to glue them? super glue?

[Cedric]

The blue brush from bro thc. The translucent spacer was sawed off a ball point pen. Used lots of superglue to put it together!

[RockyBoy]

Which pump are you using, bro?

[desm0nds]

How do you remove the assembly from the pump?

I tried opening up mine. I can see the entire blade part but i just couldnt pull out the entrie assembly.

[Cedric]

I'm using an Atman 105 pump. The impellor cannot be disassembled. I had to file and saw it apart.

[desm0nds]

file and saw it apart?!

saw wat apart? the pump itself? cannot be right?

i think my mistake cos my question very misleading.

actually i am asking you how you remove the whole impeller out from the pump? Not how you disassemble the impeller itself.

[Cedric]

Well, if you are refering to how to remove the impellor from the Atman pump, I simply twist off the cap to remove it, and pull out the impellor. Should not be difficult. Are you using an Atman?

[desm0nds]

oki will explore mine more. Nope its not an Atman though.

Cedric, have your test run the impeller? How is it going? Just curious, is the super glue strong enough to hold the centrifugal force of the rotating impeller?

one of the glaring weak points of the needlewheel skimmers is the weakness of the needlewheel impellors...

as there is considerable load on each pin of the impellor compared to the normal impellor that the same pumps were made for....so premature failure is to be expected....

those single piece needlewheel impellors already face such weakness, let alone glued together impellors..no matter how strong the bond is...it's running the impellor 24/7, months....year....

but just make a few to keep in hand in case they fail, just change to another impellor lor...

I've running it for the past 3 days. Seems fine (so far). I'll let you guys know if and when it fails. *cross fingers*

[firestream]

can show how the pump look like as a whole picture ?

Interesting on how to make the air hole for the needle wheel to suck in air ...

Hi Cedric,

Just came across this interesting thread. How is it functioning so far?

I'm using a Weipro venturi skimmer, can I replace the normal impeller of my skimmer powerhead with this DIY needle wheel impeller?

[Cedric]

Hi Sunny, the impeller is working fine. However, for it to work on a Weipro, you need to move the venturi to the pump inlet so that the air gets chopped up.

Will look for some cheap circular hairbrush to fabricate one

[rockfish]

hi all,

this topic is indeed interesting, but why is there to make into a needle wheel..??

i just install a few air tube at the intake of the power head, and the bubbles that it produced are so fine that make the water look like milk, and the skimmate is very thick .. like soya sauce.. the only thing is that the weipro volume is too small so the capacity very little ..
