Anyone ever make a self propelled rotating spray bar?

hi

this is my first reply, hope its ok.
im from oz and im using a spray similar as to what your talking about. i bought mine over the shelf. it has small plastic ball bearings, and it takes very little pressur to spin. i put it over a 300mm or 1 foot pipe, by 4 foot long full of bio balls. with an end cap that has a couple of 1 inch holes in. it works really really well. just make sure it spins slow and you will be laughing.
 
Does any body have details on how to make one of these rotating fittings or where to buy one. I am looking to build a self cleaning pump pre-filter and cannot seem to find the rotating fittings I need. Any help would be greatly appreciated.
 
I believe he said he gave up on it.
 
I've made several of these over the years and I've found the best way to power them is by pumping water up to the rotating sprayerbar with a pre-filtered powerhead. I put filter socks or DIY eggcrate foam pad holders for bulk filtration and run the powerheads out of the sump into my bucket biotowers.

I also build the rotating fitting out of 1 1/4" fittings, a nylon washer that fits inside the fittings and a cut down PVC end cap. I'll do a mock-up and post it soon.
 
hi there,

I've been looking around myself for a simple and cheap rotating spray bar. I tried a drip plate and some small sprinker heads, but to be honest, a lot of the media doesn't get wet. You need that constant rotation across all the media.

Can you post up your diagram for the rotating part?

I've hunted high and low just for the swivel part, has it got a name? Swivel union, barrel union or something? Half the battle for me is what is it called :-/

hopeful of ideas here :-)
 
Cool idea, but as already said, mostly a dead end plan Many problems, no solutions.
Would think a manifold for your drain line, going to drip pipe over something like plastic pegboard would give you max dispersion with min headaches.
