Modifying Power Sluice question?

[Storm180]

I bought one of those prospectors choice combo sluice / highbanker / w 1200 gph pump. Here is the link Combination-Units

During my initial testing it does work pretty well but I was looking to run a little more dirt through it quicker. I was thinking of getting a 2200 gph pump for it that would run through the header box and then add a single sprayer bar to the top of the header box using the original 1200 pump. Or is the 1200 enough to run it and then add a sprayer bar on another pump with something like 1000 gph or an 800 gph.

I figured I would probably lose pressure just running the 1200 through the box and sprayer bar so I thought the 2 pump setup would work out much better.

1200 is half the flow you see and your inlet size is going to restrict you as well. Im thinking a larger pump with the additional spray bar should do well for clearing larger gravels say to 1/2. Running that 1200 will require you to classify to 1/4 or less to be effective and manual classification reduces the amount of material you can run because you are spending all of your time running it. We are going out saturday and sunday if you wanna go... Call me, you have my number

Well the inlet on the back of the hopper is a 1 inch tapered hole and the pump has a 1 1/8 tapered hole. I was thinking about adding a 1 in PVC spray bar across the top and have that connected to it own pump or could the 2200 run both of them at the same time? While I am already classifying to 1/4 for material I was looking for a temporary quick fix to push more dirt until I get the my highbanker / land dredge combo.

I will give you a call Friday afternoon / evening and let you know about the weekend.

Good day all,

A quick note no one thinks about with the larger bilge pumps (2200 and up) is the hose outlet size. Some pumps come with different adapters for outlet hose size. If you have the 2200 gph pump, but only run the 1 1/8" hose you're truly only getting about 1800 gph due to hose restriction. If you want to see the full 2200 gph you need to run the 1 1/2" hose and fittings which can be a bit large for a typical production recirculator. The physical size of the fittings is large and can be cumbersome to adapt to smaller units, if you can get them to fit at all.

On my units even when I go to a 1600 gph pump I upgrade all the fittings to 1 1/4" for full water volume to maximize the pumping capacity.

Just food for thought before you shell out the extra money for a larger bilge pump.

I Hope this helps,
Chris
