How to Choose the Right Dredging Pump

The success of your dredging project hinges on selecting high-quality pumps. Here are some factors to consider when choosing a dredging pump:

Dredging Material Type

The pump’s efficiency might be influenced by factors such as material density, viscosity, and particle size. For example, dredging sand requires a pump that can endure abrasive particles.

Size and Depth of the Water Body

Another critical factor is the size and depth of the water body where the pump will be used. The volume of material that needs to be moved dictates the pump size required, while the depth of the water determines the necessary length of the suction hose.

Water Pressure and Flow Rate

Flow rate refers to the amount of water and sediment the pump can move within a given time, while pressure is the force the pump can produce. A pump with a high flow rate is essential for swiftly transporting vast amounts of material.

Stantard pump!!!!!

So I am planning on going on another trip to Georgia to prospect in the Dahlonega region. I currently have the large Keene sluice, and want to turn it into a dredge. I understand the basic concepts of how a dredge works and can easily get all of the parts to build it. Myself and my dad have a lot of knowledge when it comes to this type of work. The only question I cannot seem to figure out, however, is what type of pump to use, and how the pump situation works. I see on the threads people talking about Keene and Proline pumps. I am wondering if a simple water pump, such as the 2-inch duromax 7hp pump for just under 200, would do the job? Moves 156 gpm. Or is there some other type of pump that you need for dredging?

The pump you are referring to will not work because it lacks sufficient head pressure. Head is quite distinct from a pump’s ability to pump GPM. For instance, I have a pump that can pump 11,100 GPH, but its head is only about 80. On the other hand, the dredge pump I am installing on my 4-inch dredge build from Keene has a head of 210 ft. The tolerances are much tighter on a pump designed for dredging. A semi-trash pump will not work at all; their best use is for a high banker. However, high banking is very labor-intensive and can be particularly challenging if you’re older, like me at 60 years old. That's why I am building a 4-inch dredge. Hence, you need the right pump. Keene and Proline offer the correct pumps, and they are your best bet, or you can buy a used one!
