View Full Version : Turning jebao into needle wheel pump

Has anyone tried this? Got a skimmer with no pump. Had a jebao dc9000 lying around. Ordered these parts to turn it into a needle wheel pump. These parts are made from a 3d printer. Haven't had time to install and try yet.http://images.tapatalk-cdn.com/15/11/03/0d8458195ccbedbf7525e878c58f2c56.jpghttp://images.tapatalk-cdn.com/15/11/03/08d1b51d518acb30802fd3762e9890e3.jpghttp://images.tapatalk-cdn.com/15/11/03/e244174d374621102c9e3ea2d4d7f1e7.jpghttp://images.tapatalk-cdn.com/15/11/03/4890b95d960629ada2132dcd96b97202.jpghttp://images.tapatalk-cdn.com/15/11/03/7c35e694dab5ad4c2602466921d32e1e.jpghttp://images.tapatalk-cdn.com/15/11/03/53ab281cc91d3de6144af67223708ef3.jpg

Intriguing. Can you post a link to where you got the parts?

If it's designed to do it I'm sure it will go over easily. Needle wheel makes a difference for sure. The adjustable speed I'd imagine will be a sweet addition to simplify skimmer tweaking too.

Lol dc9000? Do you plan on using something the diameter of a 5g bucket and about 6' tall for a skimmer? That's a butt load of flow. I have my 120 running on a manifold with two 3/4" outputs and a ton of flow on setting #2

My sedra 15,000 will do the same.... until you open the venturi.

Can't wait to see it in action, skimmers rated for 400g use a dc3000 equivalent

I thought a sicce psk 1000 was 880 gph. Dc 9000 is 794 gph on lowest setting. Skimmer is almost same size as a g4. I figured a needle wheel would reduce gph versus an impeller with blades. The volute is also adjustable for flow. Ad said a dc6000 would probably be a better size. I figured i could try to make it work for $45 instead of buying another pump. I'll post link when I find it.

You were right levi a smaller pump would work better. I got the dc9000 to work by reducing the inlet slightly. So the parts work just my hope of using an existing pump didn't. Does anyone know if the impeller size for the 3000 or 6000 are the same size as the 9000. I do know the 9000 and 12000 are the same. Heres a video of it in action. https://vimeo.com/144577884

Yeah psk 1000 is a beast. I love the wheel though on your mod. There is a company that is doing those paddle wheel style impellers and from what I have seen they are superior to needle wheels. I can't wait to see it in action!

Try reducing the output instead of the inlet, the inlet reduction will hurt the pump but the added head pressure of the output will not. Love the video!

Yeah I'll do that. Just was easier tonight to reduce the inlet to make sure it would work.

I wondered why I saw that ttt on a thread I had just posted to. I said to myself, "Wtf is Tim ttt-ing a thread I just sent ttt?" Nooooow I get it. Once again schooled by the superior intellect....

Put a ball valve on the outlet side of the pump and use that to throttle back the flow if you need to. Gate valve is finer adjustment but you can manage with a ball valve.

Tried both a ball valve and reducing pipe size on outlet of pump. Seems like any reduction on output side it quits producing bubbles. Blocking inlet of pump is the only thing that makes it work right. Right now center of volute is blocked and I'm using adjustable outside to adjust flow. Works great that way but I don't wanna burn out pump. Can't think of anything else to try besides just getting a smaller pump.

Could sell the 9000 and get a 3000 with built in volute and needle wheel from fish street

Where is your air being taken in? Most likely placing it in the inlet path (h2o intake to pump) or past the ball valve towards skimmer will keep air flowing. If it's between the outlet of the pump and the ball valve, the pump is going to try to push all the excess h2o out through the air intake line.

Air inlet is on the intake side of pump.

Some people add an air pump. I have a all one you're welcome to have if you'd like to try it?

Also adjusting the air line closer in towards the wheel may help. Could you post a picture of the area where the air enters the pump?
