Kent Nautilus TE modification

[120reeferman]

i have 2 of these skimmers now, i just purchased one with a crappy mag 5 pump pretty cheap, the other has a hailine crack in it, it barley leaks but still works, what im woundering is, since i have the new one, i want to try and modify the cracked one, what do you think would be cool to do to these guys, personally i like the way it is desiigned, most dont but i do, i was thinking about maybe using a needle wheel pump on the new one anyway, but what about, a needle wheel on the old one, with 2 say mag 5s churning up the mix???

Did you ever put a needle wheel on that TE? I'm considering getting an Ocean Runner 2700 to replace the Mag 7 I have on there now, and keep looking for someone that has done it already b4 I spend the money.

isnt the nautilis a venturi skimmer?? as in it introduce air bubles via a venturi and not by suction like needle wheels?? so anyhow.. if it's a venturi.. how would a needle wheele help it any?? unless it's a modified skimmer so that it will re-circulate..

I thought needle wheel based skimmers had venturis on the inputs of their pumps. That's how they suck in their air.

SOme use additional needle wheels pumps to recirculate the water in the reaction chamber.

billag, you are right. The OceanRunner replaces the current pump, its not just a needlewheel adaption for the current pump - though I have considered that.

I have the Nautilus EX 24 and I like it well enough. Once we sell enough frags, I'm going to get the OR2700 and hook that up and it should work wonders based on what I've read.

well.. when i think of a true venturi.. i think of the duble ended funnle thing with a ait port hole in the top.. that is what i thought they had on the nautilis.. that is why i reasoned the way i did on the last post... cuzz those types of venturi introduce air by water pushed into it.. the needle wheel skimmer's venturi introduce air via the sucksion from the pump intake..

A Venturi is a fitting or device that consists of a tube constricted in the middle and flared on both ends. A fluid's velocity will increase and a fluid's pressure will decrease while passing through the construction. Placing a tube or pipe at the constriction point creates a vacuum. Fluid or air can then be drawn in through the tube.

Image is of a very simple Venturi.
As the air/fluid (blue lines) goes around and past the the inner tube the air/fluid (red lines) get drawn (suction) through the inner tube. The inner tube does not have to be constricted or flared. We use these in our mufflers to suck the dust out of our air filters.

Doesn't the "eductor" that fits on the intake of the pump work as a ventury on the pump intake? It takes air in by the difference of pressure through a restriction. Then introduces the air laden water to the pump impeller. I think this is right.

bring this back frm the dead, could i hook up a small pump to the venturi? or put some holes in it and mak eit a recirc?

YES
