12 vot pump
« on: February 01, 2011, 03:04:24 PM »
 I have a small sluice box that I am going to try to make into a recirculating highbanker. The sluice is 9"wide and 24"long with 4 riffles spaced 4" apart. What I need to find out is what size pump I should use? If I can get something that does not cost to much then maybe the wife will let me buy other stuff. Gene

Depends a bit on riffle profile, but would say for 9 inch wide sluice box, around 35-40 gpm pump, you will probable neeed a ball valve to fine control the water flow as well........Guest

I agree that for a box that size you'll need in the range of 35gpm minimum. If it's for a home-based concentrate processing sluice you can get a 115V sump pump at reasonable prices. For the field, look at the Johnson line of pumps and use a lawn-tractor battery.

I use a 1200 gph 12 volt bilge pump on my setup,it's a 48" X 10" recirc.Works like a charm for me.Pumps are about $30 around here..
