Jul 16, 2011· Not good for any real dredge at ALL. Look for a centrifugal style pump, a trash pump will barley work for shallow stuff but does not have the pressure to really produce.

Jun 13, 2018· A gold dredge is powered by a motor and pump. A common misperception is that gravel is sucked through the pump. The pump actually pumps only water, which is delivered to a venturi type device (called a power jet or a suction nozzle) which indirectly creates suction in a larger hose.

This is a real workhorse pump designed to power a 3 or 4 inch gold dredge or a large combination dredge hibanker unit. Pump is made in the USA and engine in China. Assembled in the USA. Compare the price to comparable Briggs and Stratton intek or Honda pumps. About 100200 cheaper! SPECS: 240 gallons per minute maximum head is 155 feet

In harsh conditions with sand, sludge, rocks, slurry, normal dredge pumps clog, wear and fail more often. This leads to downtime for maintenance, hurting your bottom line. Not the case with the EDDY Pump, since we have the tolerance to pump objects up to 11 inches to ensure maximum uptime and production rates in any industry dealing with abrasives, solids, and high viscosity materials.

One of the hardest things to find is a cheap high pressure pump. This pump SAYS it has 116 PSI and about 4000 gph. That should be plenty to power a dredge nozzle up to 3″. We have NOT tested this pump but it's 1/2 the cost of others. Also you can get the 4 year extended warranty for 22.

Centrifugal and Hydraulic Dredging Previous Next Another form of socalled dredging, variously termed hydraulic dredging, steam hydraulic sluicing, gravel pumping, barge sluicing, centrifugal and hydraulic dredging, by steam or electric power, has been in use.

We have run our mini (″ dredge) with the same high pressure pump as our 4″ dredges. We simply let the motor run just above idle. Running a 2″ then move the throttle up more. Running a 3″ more. etc. GPH is usually not the key issue with pumps and dredges. Most highpressure pumps have good gph.

Feb 09, 2016· While unemployed in the winter of 201516, I set out to build a 3" gold dredge on the cheap. I acquired most of the components for it, but still needed the part that does all the work: the water pump.
