Not sure what you are asking here, are you talking about running a HBer away from the active waterway and shovel material into the HB, running dredge up an land like a traditional dredge (aka booming doodle bugging etc), or are you talking about pumping stream bed material out of the water, 20 feet away and up into a HB?

Yeah man, you can mod your dredge into a HB'er, although if I had to I'd float my dredge, and run a 20' line off my pump to a real highbanker. Dredge sluices are designed for water to be pushed over it. HB sluices rely on gravity and pitch as well as flow.
 

I thinking of pumping material right into a high banker on the bank away from the stream , I'm thinking it would create less silting , and be more eco friendly to the area's , I may be able to work .

The amount of energy needed to suck material and then pump it is makes this a no go. The holding pond you would need for something like this makes it a no go. The amount of agency attention you would get makes this a real big no go. Sorry I know this is not the answer you were looking for

I was thinking that , I was just wondering if anyone had done anything like that . Thanks for the reply .

I understand what your saying , but if the high banker was set up below the mean high water line , before the actual river bank , IE a gravel bar , ETC . You should be able to run it and let the water go back to the sorce ., right .
 

Highbanker/dredge combo's that come without floats is what I think your asking about. These can certainly do this to some extent but they have limitations like total hose length and total lift to the HB above the waterline. Whenever you increase either one, you reduce the suction level. This can be compensated for by increasing your operating PSI to the jet or running another jet in-line but this could require a larger pump than the manufacturer supplies with the hb-combo depending on your setup.
 

EZ to do with deep pockets, just a bigger pump and/or a extra jet and good to go. Little trick is to go higher than the hb up the hillside and loop back down to get a helping hand from gravity from the water flowing back down hill. Solid hose mandatory as flat takes way too much energy. A nice holding pond will work miracles, just separate in the middle with a anchored tarp to make 1 pond into 2 and really works great to drop out silt. Lots of luck-John
 

It all sounds good , I have a few pumps , and plenty of hose already with being in the excavation bussiness . I think I have most everything I need except the high banker , a dredging nozzle , and I'm sure afew small items .

There's your problem. There NOTHING eco-unfriendly about dredging! You have been reading green lies. US Corps of engineers tested and determined that suction dredging has no impact on the environment.

As for your question, yes you can physically do that, but you aren't going to be happy with the results. You will spend more time fighting plugs in your on-shore line than actually moving material.
 

Thanks ! That more like the information I was looking for , I know some of you guys have had to try this . I'm in a position that pysically , I don't think I could get a floating dredge in or out of the water yet . It would have to be pretty small and lite , can you give me some ideas whats out there ? I've been thinking about a proline 2.5 inch dredge . I was wondering if anyone uses one and how well they work .

If you have a big enough pump you can put a Y in the high pressure line to feed another inline jet to act as a booster somewhere in the middle. This will help keep things moving for a farther distance and/or higher lift.
 

I've run a 2.5" suction nozzle into a HB placed about 3 feet above the waterline.
We ran a 5 horse Pacer pump to the nozzle. Suction was good but not great and large rocks in the hose moved slowly.
Hose plugs were a problem, but it is doable. We were straight arming it with no air, so not that deep in the water.
