Dredge nozzle sizing: Example: A ke-sn32 dredge nozzle measures 3quot; x 2quot; --- the suction nozzle outlet measures 3 inches and will work with our 3 inch suction hose. It has a net weight of approx. 6 pounds. A 2 inch pressure hose is easily secured to the nozzle with a 2 inch threaded coupling. Read More

2.5" dredge pump specifications. PHP160 pump produces up to 200 GPM and up to 160 foot head. 2.5" suction nozzle works at 78 GPM at 45 psi. 2.5" power jet works at 106 GPM at 40 psi. 3"and 4" dredge pump specifications. P180 pump produces up to 250 GPM and up to 160 foot head. 3"and 4" suction nozzle works at 106 GPM at 45 psi

Flow from these pumps is directly proportional to the pump speed, which is why they require a relief valve and bypass line between the pump outlet and the nozzle shut-off valve. Roller pumps : This is the most popular pump with farmers world-wide. The seal and roller materials should be selected based on their compatibilities with the ...

Nozzle: Here's an easy project: really all you need is a piece of pipe about 10 inches long and of the right diameter to fit in your dredge hose. Simply take one end of the pipe and saw cut the pipe about every quarter inch. Take a hammer and gently tap the pieces down to form a cone on the tip.

Pump and piping sizing June 2019 Jacques Chaurette There is no reason why anyone should not be able to go out and buy a pump, do the installation, and be satisfied with the results. There are 3 things to establish: the flow rate which can be easily determined, this is your basic requirement, the height to which you need to deliver

A new jet nozzle just a bit larger diameter than the last one to better accomidate the bigger Rule 20amp pump I used a 4 to 1 ratio for the jet, the abs is 2" x 1 1/2" fitted with a 1/2" jet made from a Home Depot fuel funnel that is set in 2" abs held in place with automotive auto body filler.

2.5" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other 2.5" dredges were floating on inner-tubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline 2.5" dredge sat on sturdy pontoons and used a power jet for dredge vacuum.

4 Replies and 883 Views Priming a Keene P185H pump 883 4 Started by [email protected] We have a Keene P185H pump with a Honda GX200 motor for our 3' dredge. The motor runs like a champ. Our question is what is the best and easiest way to prime this pump. We fill the intake hose to full capacity with a small electric pump but still it doesn't pump any water.

Here is my new / old dredge. I have modified my old Gold King from a 2" dredge, to a 4" dredge. It now has a brand new 5.5 hp engine, 4" proline power jet, swivel nozzle, new miners moss, and some expanded metal classifiers of several different sizes, …

For example, if your fountain spout is 1 inch in diameter: 1 x 100 = 100 GPH, your pump will need to be rated at 100 GPH. Measure the entire height of …

Well my first dredge was a 3 inch I made everything except the Motor & pump . I had a flared box which I still think was the best. Didn't even have a wet suit or Air that first year. Damn I got a lot of gold. Then I bought a used 4 inch crash box that I am still using 18 years later.

May 27, 2017 - Some more field demo's of the Hydro-Force 250. The only hand held, dry land dredge nozzle.

Nozzle: Here's an easy project: really all you need is a piece of pipe about 10 inches long and of the right diameter to fit in your dredge hose. Simply take one end of the pipe and saw cut the pipe about every quarter inch. Take a hammer and gently tap the pieces down to form a cone on the tip.

The pump is a Keene P-150, I assume pumping in the 200 - 250 GPM range. It has the old paper gaskets for the pump housing, will Auto gasket maker work to replace those if needed? I think the main pump seal is still the same as modern pumps. For the Sluice it has a plate in the crash box then flat red carpet under the riffles.

As i am thinking about building a dredge, I want to know what size of dredge pump can i use to build a 4 inch, 5 inch and 6 inch. the Robin 4 inch water pump I had is not suitable for dredge as i was advised. now if I am building a 6 inch twin engine dredge what size of pump can i use? a local welder in my area had

Second, do I need to change the discharge nozzle's screw when I go to 37 squirters, or is it for anything greater than 37's that I switch the screw? Third, when do I make the call to switch to a 50cc pump? Is it when I run out of gas on the pump shot with the larger nozzles? Or is it by default when you get to a certain nozzle size?

Hoses, motor/pump and sluice are not included. A water source is required for your water pump. (3,600 GPH water pump or 2" dredge pump required.) The HF 200 is light weight and easy to use, it can get into tight spots and just like the larger units, it has awesome dry land suction power! Includes an instructional DVD to help get you started.

The dredge is powered by a 2.5hp 4 cycle gasoline pump. The pump and engine combination weighs only 27 pounds and is mounted on a shock resistant base plate. Unit comes complete with everything you need for a 1.5" dredge including foot valve, suction nozzle, and all the parts, hoses, and clamps.

I don't know poop about hydraulic science & all that kinda stuff. BUT, I do know I use that pump on my Keene highbanker/dredge A-52 sluice conversion set up with a 2.5" suction nozzle with a 10' suction hose & a 1.5" 25' layflat for pressure to the nozzle & it works for me. I do run it full throttle.

I went to see the dredge in person and couldn't control my impulse to buy. Turns out the owner had modified it with Gold Hog mats (BONUS), and even threw in a bench stand and 3-wheel cart to be able to hike it to the creeks. It is a power jet model, but I'll see what it can do before thinking of upgrading to a suction nozzle setup.

In shorter terms this pump will work fine for a small maybe up to a 2 1/2" dredge, a 2" will not be a problem for that pump, the size of a dredge is the size of the suction hose, not the size of the pump's output connection. So you can understand it a little better, check out this Keene's info page on how a suction dredge works.

But by following these 6 simple rules, you can avoid premature pump failure and related pump piping pitfalls. 1. KEEP SUCTION PIPING AS SHORT AS POSSIBLE. Include a straight run pipe length equal to 5 to 10 times the pipe diameter between the pump inlet and any obstruction in the suction line.

Paint guns do not need a high pressure rating from your air compressor – around 40 to 45 PSI should do it for most models. 42. What Size Air Compressor for a Rattle Gun? Rattle guns, or impact wrenches, will need at least 3 CFM at 90 PSI for the smaller 3/8 inch models. For 1/2 inch rattle guns, you will need 4 CFM to get good results.

Two Pro-Mack 5-inch dredges were used to find rich deposits on this river in Cambodia, before a 10-inch production dredge was brought on line.. As an example of this, a 4-inch dredge can effectively sample down to around 4-feet deep in hard-packed streambed material). A 5-inch dredge can excavate about twice the volume of a 4-inch dredge down to around 5-feet of material.

less than a 4" dredge, unless it's a really tiny stream. I have tried. everything from an inch and a half up to a twin engine dual pump 5". Once you go up in nozzle size, you don't really want to go back. If you don't set your sluice box at too drastic an angle, and you don't pump too much water at high velocity across the riffles

How well a dredge nozzle will work depends on the PSI of the pump, the higher the PSI the better the nozzle will work, even on my 4" dredge which has a high prseeure pump designed specifically for dredging I will lose most suction/lift after going down around 20 ft deep, if you're only dredging 4 to 5 ft deep a pump with lesser PSI will work ...

Parts are available from China, the shaft size will not fit a US dredge pump and some of them have different bolt patterns. Real dredge pumps have a spring loaded-carbon ring shaft seal, 3/4" for up to 5 HP then 1", when you need one take the old one to a good auto parts store, they can match it and you will save about $20, buy 2 while you are ...

Therefore, there is no pump or nozzle to clog or any small pipe outlets to obstruct. While most 1 HP fountains can only pump 8,000 gallons per hour, one of our 1 HP display aerators can move an astounding 30,000 gallons per hour into the air.

The size of a gold dredge (1.5 inch, 2 inch, etc.) is determined by the diameter of the suction hose— the larger diameter the hose, the more material can be processed. A floating gold dredge is essentially a floating sluicebox that uses an engine and pump to create a vacuum and send gravel (hopefully gold-bearing gravel!) into the sluice box ...

Our patented technology at EDDY pump has a high tolerance of sizes of materials handled, with a capacity to handle sizes as large as 12 inches. The open rotor design lets anything which can go through the inlet pass through the discharge without any setbacks. A typical high tolerance dredge pump manufactured at EDDY Pumps is shown in Figure 2.
