DIY "Stream" Style Pump

[dhnguyen]

Just did it with a MJ400 (106gph) and this thing is good to go. I'll take photos and post some in a while.

Here is mine, I made it out of 1.5" pvc, propeller guard was cut from 1/4 " acrylic, no propeller yet.

quangtam7 that is super cool what you did. How did you make the center brace like that? Did you also make the slits on the PVC as well? Very nice a clean job.

Mr Bojangles,
I saw a similar mod on another forum. To stop the water cyclone from the surface, they kept the top part of their gaurd closed (no holes in top) so that water could only get sucked in from the bottom and sides. Hope this helps.

3 weeks running and still working great.

hey quangtam7 you have to let us in the secret of how you made those slits on the housing for your prop.looks super cool, i would like to make my own like that.

I used tile saw to cut those slits. Here is my maxijet 600 mod, outlet is 1.5"x1/4", I can not believe how strong it is, look at the last pic you can see the flow is very wide, the pump is 4" under water.

You didn't use a propeller on this mod quangtam7? I kinda like the look of the slitted casing you had before better.

On a side note, I did try to make the slits out of my tile saw as well previously but couldn't keep the PVC piece straight enough to make such clean cuts as you did. Mine looked like it got in a fight with a butcher knife and lost LOL

I use the same impeller that came with the pump. Here it is 6" below water and still trying to suck air in from the top.

So the stock impeller is just blowing out from the side...this is similar to the mods where people were sawing off the nozzle to make a wider outlet.

Exactly! But in oder to get more flow, you need to drill some more holes on inlet side.

Any estimates on flow? How would you describe the stream it makes? David

 

[dhnguyen]

Well quangtam7's mod is a bit different than mine since he doesn't use a propeller. But I can say that using a propeller easily doubling if not tripling the amount of flow compared against a stock PH. The flow is also very wide and dispursed unlike the narrow stream one would expect from the typical powerhead.

Hey guys I think someone stole your ideas. Check out this page - http://www.sparklingfloorservice.com/melevsreef/pics/macna17/cool_stuff.html . Scroll down to a little past the middle of the page. Pretty slick.

 

[dhnguyen]

Isn't capitalism grand? LOL

I don't like the idea of having to drill my tank just to have that though.

ok I stand...er...sit corrected. This Vortech pump looks like it doesn't require any drilling at all as the 2 halves of the pump are held in place by magnet.

Pretty slick indeed. I wonder how much IceCap will charge for it.
