Rocks, sand and gravel, up to about 1/4″ – 1/2″ can pass through these based on the pump. Most 2″ and 3” semi trash pumps are rated about 35 – 42 psi. Semi trash pumps will move large amounts of water with not too much PSI. ![]() Semi trash pumps and high pressure pumps. There are really two types of pumps for prospectors. I wish you had a link under the “pump section” on all of your Highbankers of the recommended Pump that will work for dredging also with your Highbankers. I then realized that some of the Trash Pumps only have 38psi. Is this because of the PSI? The HydroForce Nozzles require 40psi. You state in your video that a Semi-Trash pump will not work for dredging. If you want to learn more about how suction dredges work and how they find gold, check out our infographic below.We get a lot of “pump” questions, so I figured I’d grab some posts from the last year and put them into this post. It also requires a large investment upfront, with the cost of equipment averaging several thousand dollars. The process involves hauling heavy equipment, lifting and moving stones too wide for the suction nozzle, fighting against the water’s current, and lots of swimming. ![]() While it may sound easy, suction dredging is much more difficult than vacuuming coins out of your couch cushions (or gold flakes out of your carpeting). In a way, the process is like a combination of the best parts of gold panning and gold dredging. These materials pass into a floating sluice, which filters and recovers the gold. It sucks up rocks, gravel, silt, and anything else at the bottom of a streambed using a gas-powered pump and suction hose. For the amateur prospector who wants to take their hobby to the next level but doesn’t want to work in a mine, upgrading to suction dredge can be a great way to find more gold while still enjoying the great outdoors.Ī suction dredge essentially works like a heavy-duty underwater vacuum cleaner. ![]()
