What i want to use the pump for, is to suck up gravel on bed rock and run it through a sluice box. I need no more than 50 to 60 feet of total head. This is a unit i will build, and it dosen't have to fit a exsisting aplication. What it needs is to be able to use a screenless 6 inch hose and be able to pick up the gravel and gold off the bed rock. I have a new 85 hp diesel to power it. Thank youCountry:USA
