Need help building highbanker

[Huelten]

I currently have a 10x36 proline sluice that I am going to be converting to a highbanker. This will be my first experience with highbanker as all I've used are stream sluices. My question is regarding the water pump that will be needed for the highbanker. I'm going to use a 12v submersible pump, currently I own a 1250 gph pump. Is that to small to run enough water? If so, some advice on what gph I need to run would be greatly appreciated. I'm set on a 12v pump and not a gas pump however

If you're going to be pulling your water from a stream then gas is the way to go for sure. Even with a 4000GPH pump, by the time you get the water through the hose, overcome gravity to get it up the bank and go through all the fittings, valves etc that's a LOT to ask from just about any 12V pump.

Keith can tell ya that out here there are a lot of us that run recirc systems. We pretty much have to due to the lack of water. As a rule the only water we have to work with while out in the field is what we can haul in with us.

I'd still figure out a way to catch your tailings until you have your system dialed in though. No sense in doing all that work and ending up loosing gold until you get it set up right.

This is from Goodguy. This is a Fluid Bed Gold Trap that attaches to the end of the sluice. Any fine gold will be trapped inside the tube. I started to build one for my sluice and still plan on building it.

yep ole goodguy comes up with some good ideas!

There is a sluice made using this design. I think GoodGuy may have gotten his idea from the sluice. Either way its a nice setup to have at the end of your sluice as the trap is liquified with a divider traping the gold but allowing everything else to pass through thats lighter than the gold. The hose attachment on the side is hooked up from your pump with a balll valve to make flow adjustments.

Azviper:

after looking up the laws it appears the laws are the same regardless of gas or electric, i just had to dig deeper than i had before. so with that being said i looked into some gas pumps, whats your opinion on this pump from harbor freight.
Powerful 212cc 4-stroke overhead valve gas engine
9540 (GPH) (gallons per hour)
Total head lift: 97.5 ft.
Suction head lift: 26 ft.
Low oil alert
Recoil start
$179.99

or this one

Powerful 79cc 4-stroke overhead valve gas engine
2220 GPH (gallons per hour)
Total head lift: 105 ft.
Suction head lift: 26 ft.
Low oil alert
Recoil start
120.00$

one seems to small and the other too big, any advice?

Check out the DuraMax 2 in pumps on Ebay. Cheap and recommended by Heckler Fabrication. Nothing says you have to run at max output on any gas pump. Way better too much pump than too little. bypass control valves allow flow adjuztments without associated issues on elect pumps.

Stan this is why I suggested gas power. I am using electric as I know how control my pump, but someone that does not have experience with electric motors may have issues. As for the Duramax Pump that a great price and free shipping. I may have to look into one of those pumps. Click on the link in the sentence... Duramax...

AZ, that pump makes me think of grabbing my bro in laws two kayaks, strapping it all together, hook up a two inch hose..........oh yeah,
Bad AZ Viper, bad

Keith, it was not my intention to step on your toes. Trying to run a battery powered electric pump and draw from a stream is not gonna work IMHO so it's really a moot point. Those Duramax pumps look good to me and I will probably order one to have on hand.
It would def work with our reverse helix trommel. I am going to work on the spray bars in the hopper so they do a better job of washing rocks and that will require more volume and pressure than the present 110V pump can supply.

For times when you might not be able to get close to a stream there is a solution. Two pumps in parallel will double the capacity but two in series will double the head. Sometimes a mechanical engineer will spec two pumps because two smaller pumps are cheaper than one large one. They will chose parallel or series depending on what they want to achieve. So feed the out put of one into the intake of the other.
These are approximates as system design will affect the published pump curve ( performance) so with hoses, fittings, other restrictions the actual increase will probably be less.

Stan you were not stepping on my toes bud. Its all good that Huelten gets input from many so that he can make a decision on his own. I hate to tell someone what to buy as it may not be the best choice.

Huelten what did you decide on in regards to pumps?
