turn a two inch trash pump into a dredge

Listening to the guys that do the dredge at Storm lake, it sounds like that is tough feeding that thing.

I think it would get real tiresome handling the hose to feed just the right amount of water and silt into the heavy hose. You can use one of these diaphragm pumps if you want. That would throw a lot of stuff in a hurry. There was a deal made that used air and venturi idea to suck water and mud out of concrete forms that got rained in before concrete gets poured.

If I had a setup that worked, I could just do a little maintenance every year to keep it clear. It kept clear for about 4 years and slowly silted in.

I use them for pumping out grain elevator basements. I have a couple of the 3 inch diaphragm pumps.

There will be a venturi in the suction line where the pump outlet attaches to create the suction. Pump will have a floating intake and suck just water.

Lots of pumps for sale but some say trash or dredge but have a cast iron impeller. I was thinking of a 3' or 4' trash pump or dredge pump with some sort of high pressure nozzle to stir things up. I am clearing out material to make access from a river to the bank. I assume I need a chrome or hardened steel impeller and wear plate because of the sand and small gravel. I need to do some small scale sand and mud dredging. Posted 09:53 (#5331580) Subject: Small sand/mud dredge setup Small sand/mud dredge setup Jump to page : 1 Now viewing page 1
