Jun 01, 2016 The result is the ability to pump material at solid rates of up to 80 percent while recovering the heavier gold. The higher solids content through these 4-inch pumps requires a sluice box normally rated for a 12-inch centrifugal pump. Without strict tolerances, the pump can operate for extended durations without maintenance.
Feb 08, 2017 High pressure pumps have different “water moving” parts with tighter tolerances. (for lack of a better word) This gives them higher pressure. On a 2″ it might range from 70 – 95 PSI. Often the GPH is about the same. If you are dredging…. you always want to overpower your unit with psi.

Description of the Suction Dredge The suction dredge (Figure 1) consists of ﬁve major components: (1) a gasoline engine-driven pump, (2) a pressure hose, (3) a suction hose, (4) a return hose, and (5) a series of wash screens. The engine-driven centrifugal pump draws water through a 3.81-cm inside diameter pressure hose connected to a suction
How Our Dredge Pump Handles Solids. Simulation video of the EDDY Pump compared to a centrifugal pump. The EDDY Pump shows its superior ability for high viscous pumping, high corrosive pumping, high specific gravity pumping, and high solids pumping, while being a low maintenance pump that is also a non-clogging pump.

gold dredge centrifugal pressure; Prospecting Water Pumps – Some Basic Thoughts – Gold and ... Feb 08, 2017 There are really two types of pumps for prospectors. Semi trash pumps and high pressure pumps. Semi trash pumps will move large amounts of water with not too much PSI. Most 2″ and 3 semi trash pumps are rated about 35 – 42 psi.
