Hi guys I'm in the process of making a small sluice to use at home. It is only about 200mm wide and 2mtrs long. Just wondering what sort of water flow I need to run it. I want to run it as a recirculating system and figured that maybe a pond pump from a hardware store would be able to do the job? The cheaper the better! Any suggestions would be great!
 
what are the available power supplies and what are you going to use in the way to capture the gold, riffles expanded mesh or some type of rubber matting

Power will be mains 240v. I saw a post in the diy section by aushunter and he used some pallet angle as riffles, I intend to do the same as I have loads laying around. Followed as you mentioned by either some mesh or matting I'll see what I can find.

I now realise that this post should probably be in the diy section too :8
 
Hi everyone, I want to set up a water flow over my little Angus Mackirk sluice to run cons at home, I don't know what sort or 12v pump to get whether it should be submersible or not, what hoses to use etc, how to set it all up. And should you have some sort of hopper at the feed end, and some sort of way to disperse the water evenly over that sluice?
 
I use one like this pic. I think it's 700 GPH and I put a valve in the hose to control flow rate. I got mine on ebay but boating and camping shops should stock them.

The white bucket catches the tailing so the don't go back through the pump. Works quite well.

with this set up the bucket that the sluice flows into should have 10mm holes drilled 100 mm down from the top for the water to flow back into the outer container... lets things settle out better...works great... I will post a pic tomorrow of mine in action... :)
 
Any tap/ valve will work. I used one like this because i had it.

Maybe go for a higher flow rate. You can use the valve to slow the rate but cant get more flow if the pump isnt big enough.

I'd go bigger, same as ramjet says you can always reduce with plumbing but too small a pump is worthless.
This guy for example.

10bux more.

Or you could go bigger...if you want to use it for more than one thing.
This is what I use for my highbanker.

Side note. Layflat hose wont really work with these pumps, they have volume but not pressure.
 
Thanks RJ and magnetic. So what hose is best, is it 1/2 inch or there abouts?
 
So something like a big garden hose? With the valve RJ, it has threads how do you attach the hose to it? You'd have to have some soft of threaded 20mm say to screw in and then something that the hose can be attached too.
 
I can get a 700-800 GPH through work so I'll find out a price and get back too you Lenn.. considering one myself so I will find out soon!

Two of mine that might give you some ideas.

The larger is probally the more interesting. 3700gph. Complete with a halfassed camlock. Pilfered lamp switch and a 12v automotive battery voltage monitor.
