pict2... diy needlewheel pump...

pict1..

that's my diy needle wheel pump...

now u dont................

now u see it...........

is JS200L.. venturi driven model

same type of glue to stick glass together....

actually, u should chg to 2 pump, cos u may need to off 1 pump at times... And I got the same effect as u(very big bubble).. stuffing air tube into inlet of pump.... so is not a full prove method... so the best is still DIY needlewheel or injector....

first attemp on the DIY needle wheel.. fail... no fine bubble from the pump. will chg to another type of brush..... will try tonite

just to make use the plastic container which left over during hari raya. Still DIYin Needle wheel and Injector.... Yes... prepare the worst liao...

now only thing left is either DIY injector or needle wheel....

interested on ur micro skimmer .. if buyer back up.. txs

all ac 230V fan

I have a few 4 to 5 inch fan to sell at $5 each. Will pose the detail later.

think of it... the problem lay on ur inlet. cos u slow down the water into the needlewheel. By twisting the inlet, is the same as close the valve of the pump. I modifying a pump, change to needlewheel and air hose on the inlet side. Will pose a pict once I get the needlewheel done.

think u need to reduce the inlet pile smaller. as u observe the venturi, the air tube is at the narrow water pass thru side.
