Time For Some Good News!

Take a minute to read this very exciting article by Shannon Poe at the American Mining Rights Association!

Firstly, we know you are as skeptical as we are, after all, we’ve been told things over the past 9 years (like rulings from courts and such) which give us hope, but it always ended up being the same BS, delays, denials and shutdowns The small mining community donated millions to go to court, Brandon Rinehart was dragged through many court battles and that too we all donated to. All to no avail... Continue Reading

Nah, put a sluce on it...6" or 8" gold dredge...although 37 hp would create enough vacuum to tear your arm off.

I need to buy a old junk air pump

Bryan Gray new toy lol

The new 4” ultra dredge is now equipped with our latest sluice box improvements the Slow Flow sluice box. We have added 1/4” woven wire classifier screen to the back end of the box. This drops the water speed in half under the screen. Under the screen is section medium expanded metal covering a section of miracle mating providing unsurpassed fine gold recovery in a compact light sluice box. ... See MoreSee Less

We can use this in Ca ?

I'd like an upgrade kit, too! Just bought mine last year.

I like it!What is the price for suicebox and jetpower only?

Oh my god she's pretty 😋

Will you make an upgrade kit for the previous model?

Does this make the 3 stage sluice box obsolete?

Will you make an upgrader kit for thé previous modèle?

What do you think is fine gold? 30 mesh? 50 mesh 100 mesh? 300 mesh?

200 to 600 mesh

Jay Dabliu Peni u need this in PNG

ALRIGHT HEY NOW♡☆

4 Stroke engine no more mixing gas with oil also the reliability is the best. We also have a screw on lid. We aslo have dual ports so the motor works on top of the bucket when powering the dry washer and when being used as a shop Vac.

The price for the Wet is kit $299.00. The price will go up higher soon, just the pump went from $39.95 to $99.00 The sliuce is twice and long and way more work. The hopper and classifers are at leat twice the cost of the previous hopper system.

The combined price for everything is 1539.00 for everything

The HVS blower / shop vac is $445.00. Our set up is the best in the business. We chose the Makita for several reasons.

The price for the 160 dry washer is $795.00

Rich does pay attention. This time he attached the flood hopper and sluice trough extension in place of the flare. He also stepped up to a larger pressure hose. Just the larger pressure hose should provide about 25% more water flow into the sluice box. Rich also made a nice little PVC Stand. Not great in the field but ideal for home usage. ...

Good observation he had to run it at the stepper pitch since he was not getting enough water due to the small hose once he runs it with the larger hose he should be able to flatten out the box.

Using different types of pumps for dredging and high banking
Typical Keene pumps run in the 150 foot head range. Pump head is a function of pressure. 150 % 2.3 = 65 psi. This high head pump works great for dredging and high banking. Our pump are much lighter, more compact and extremely higher performance, than any other type of pump. Most of our pumps can accommodate the use of an air compressor at a latter date.
Many people buy the cheap Chinese or Harbor freight water pumps that do not work well. Keene now builds pumps that will fit on a 5/8th threaded shaft and a 3/4” keyed shaft for the 4-6.5 H.P. motor configurations. We also make our larger pumps that will accommodate a 1” threaded shaft and 1” key way shaft from 8” to 23 Hp. motors. The cheaper engine are ok for the miner that does not use his dredge/ high banker more than a few weeks a year. If you are a serious miner spend the money and get a engine that will last for years of hard use.
Typical trash and semi trash pump run at 80 to 90 foot head range and produce only 35 psi. These pump work ok for high banking and poor performance at best on a dredge. Dredges like a balance of both volume and pressure. Only Keene pump will work with a air compressor.
Electric pumps home owner types work ok, for very small high banker and not at all for a dredge. The head lifts on these pump are typically around 25 foot of head only around 10 to 15 psi, so this means you need tp run short hoses and make sure the hoses are largest that the pump will take. Since the head lift is so low these are extremely sensitive to longer, small diameter hose and the high banker should be a water level.
12 volt pumps are extremely low head left around 5 to 10 foot head lift and under 5 psi. So it is very important that we keep the high banker at water level and you can not use a spray bar. Spray bars will restrict the pump to much and you will reduce the water flow by 80%. So the only way to make a 12 volt pump work is
High banker is at water level. Use large short hoses to reduce friction loss Use a flood header to provide minimum friction loss and optimum water dispersion.

I wish the pump seals didn't crack after sitting over the winter. They get expensive changing them every spring.

I can tell you that the pumps on my Keene Supermax are incredible. I am amazed at how much material it will suck up. Also without opening the release flap, it is sometimes impossible to remove a oversized rock. I love my Supermax.

How much would a pump fitted for a 3/4 keyed shaft cost? I need one for a 2 inch dredge

Here are some pictures from a customer or ours. James just purchased one of our #STE sluice trough extensions for $22.00 and our #MMFHR Mini Max Flood header for $49.95 and he riveted the flood header to the sluice trough extension with a little bit of silicone sealer to eliminating any leakage.
James set it up with a 110 volt pump that should work fine however, he made the mistake of running a 3/4 standard garden hose. Larger hoses are critical when using a small 110 volt pump and even more so when using a 12 volt pumps. James is not setting the sluice box as intended, however it should work fine. The STE and Flood header is designed to be in place of the Sluice box flare. The bolt patterns are the same. The sluice is meant to be feed with pre classified material. The spray bar he is trying is a good idea however, back to no head pressure, so the flow will be restricted and he will not have enough flow to make the sluice box work properly. James also turned the hopper around and ran some flatten wire however this would not work very well since the gravel will not slide off very easy. He would need grizzly bars for the rocks to slide off.
