Question

What pump is recommended for the Excavator?

Answer

Keep things light and small. We recommend the 2.5 H.P., 53 PSI, 3000 GPH pump with 1-1/2” suction and discharge. They can be bought on ebay. Do an ebay search with the following : (2.5 HP Trash Pump). They usually range in price from $130.00 to $170.00. Always check frequently for the best prices. You may also do an internet search. (Just remember……It must have a minimum of 50 PSI discharge pressure with a minimum of 3000 GPH) (Gallons Per Hour)

The specifications for this specific pump.

ENGINE

◦ Engine (2.5hp)
◦ Starting system Recoil Type
◦ Air-cool 4-stroke
◦ Single-cylinder, valve-sided
◦ Fuel tank capacity (0.34gal)

PUMP

◦ 1.5” Gasoline Semi-trash Water Pump
◦ Inlet/Outlet Diameter : (1.5 inches)
◦ Discharge head (49 ft)
◦ Suction head (13 ft)
◦ Capacity (3000 GPH)
◦ Discharge Pressure (53 PSI)

◦Total Unit Weight only 25 lbs

Not all 2.5 H.P. trash pumps meet the minimum requirements for the Excavator. The pump must have a minimum of 50 PSI discharge pressure with a minimum 3000 GPH rating. Most have a 1-1/2” Suction and Discharge which is what you want. Read the specifications carefully before purchasing one.

Question

What hoses will I need?

Answer

In addition to the pump you will also need a 1-1/2” lay flat hose with fittings for the pump discharge, 1-1/2” suction hose for the pump suction, a 1-1/2” female hose fitting for the pump suction hose.
These can sometimes be bought at places like Tractor Supply, Lowes, Home Depot, Northern Tool, or Harbor Freight or any store catering to the farming community. They may also be purchased at most mining supply stores on-line such as the following links.

We are not endorsing Rosewind Mining Supplies. This is just one source of many. Again, these items may be purchased at most mining supply companies on-line.

These links are supplied as a quick visual reference for what you’ll need.

The 1-1/2” Lay Flat Hoses may be purchased with both male and female couplings already assembled to the hose. If you can not find the 1-1/2" lay flat hoses complete with fittings you can purchase the hose and fittings individually and assemble it yourself.

1-1/2” Lay Flat Hose…….http://rosewindmining.com/product_info. ... cts_id/168

1-/2” Lay Flat Hose Fittings......

(Female End) …….http://rosewindmining.com/product_info. ... cts_id/171
(Male End)……….. http://rosewindmining.com/product_info. ... cts_id/172

1-1/2” Suction Hose for the pump suction…….http://rosewindmining.com/product_info. ... ucts_id/72

1-1/2” Female Suction Hose Fitting....... http://rosewindmining.com/product_info. ... cts_id/171

This can be any type of non-collapsible hose. You may see it referenced occasionally as “Spa Hose”.

Special Note : Never use a lay flat hose as a suction hose!

The 2.5 H.P. pump is self-priming so the strainer that is supplied with the pump will work. You do not need a foot valve to get the pump primed. The supplied strainer is plastic so you may want to upgrade to a metal one. These are also available at many on-line mining supply stores.

And don't forget the hose clamps!

Question

Can I use a larger pump with the Excavator?

Answer

Although the 2.5 H.P. pump is the recommended pump, a larger 2" semi trash pump can be used without a problem. Try not to use a high pressure pump.
You will need to reduce the pump discharge down from 2” to 1-1/2" with a reducer to accommodate the 1-1/2" lay flat hose.

You will also need to run the 2” pump at a very low RPM to get the correct water flow. People usually run these at idle with the Excavator.

Question

What are the dimensions of the Gold Hog Excavator?

Answer

Sluice width : 8 inches
Sluice Length : 36 inches

When set up and running……total height is about 24” from the ground to the top of the hopper.
When packing it in and out, the legs come off and can be put into the Sluice box. The hopper will fold down into the sluice box.

Question

What’s the advantage of having a sluice extension for the Excavator?

Answer

This answer is taken verbatim from the “Gold Hog Prospecting Tips” booklet.

"Length of a sluice…

I’m going to simplify this a bit. It’s fairly complicated.

Again… visualize with me.

-You are running a highbanker. You dump a shovel of dirt into the header box.
-A MASSIVE amount of material hits the top of your sluice all at once.
-This heavy LOAD then over fills the first few “riffles” of areas of the top of your sluice.
-So, now that these first few riffles are full and trying to process material, what happens to the rest?
Correct… it moves over these FULL areas and moves down to the next riffle /area. Once that next section is loaded and processing, what happens with the rest? You get my point, it keeps repeating. We call this incremental / sequential loading / processing / exchanging.
Again… use your visual extremes. This is silly but it helps.

Box #1 Box number one is only 12” long. Start feeding your hopper heavy and what will happen? The riffle / exchange area will become full quickly and UNWORKED material will pass over the top never being worked. Your exchange areas are full for a second or two and need a little time to process down the lights, gold and heavies.

Box #2 Box number two is 1.5 miles long. Silly I know, but visualize it. You dump material in your header box and what happens? The normally UNWORKED material keeps moving down until it finds an open or fresh area and is worked. Are you seeing it? It may take a LONG time for the material to reach the end.

This deals with sediment rates otherwise known as feed rates. Each plant (sluice, highbanker, dredge, etc) has an optimum and maximum feed rate / sediment rate. Exceed the proper feed rate and you will not have enough open areas for material to be worked. So, sluice length really needs to be paired to both the header box, sluice surface, and the feed rate the operator works on. Our new Monster Hog was heavily based on this principle. We did not want to limit feed rates so it has close to 108” of working sluice and really fast water. Our mats are designed to process material VERY fast, but like all sluices you should have a feed rate that matches your sluice bed length, exchange process, and effective working times. So… sluice length really has more to do with processing speed and feed rate speed."

Long answer short..........It increases your feed rate.

Again, remember your mining math! The more material you can process, the more gold you can recover!

Question

Can the excavator be used in the electric mode with 12 volt bilge pumps in the field?

Answer

Yes!

You will need (2) 1500 GPH 12 Volt bilge pumps, (2) lengths of 1-1/8” bilge pump discharge hose and a 12 volt battery. Simply hook the bilge pump discharge hoses (1-1/8”) to the (2) 1-1/8” barbed bilge hose connection fittings on the hopper and use the Escavator just as you would as if you had your unit connected to a gas engine pump.
We have also operated the Excavator with (2) 1100 GPH 12 Volt bilge pumps with pre-classified material.
