Sand & Gravel Pump Applications

EDDY Pump has developed various ways to avoid costly trucks associated with sand & aggregate processing and instead pump the sand and gravel directly from the pit into the processing plant. This saves the plant millions of dollars a year.

Sand and Gravel Slurry Pump Applications:

  • Construction: Gravel is often used in the construction of roads, bridges, buildings, and other infrastructure projects. Pumping gravel allows the material to be moved quickly and efficiently to the work site, reducing labor costs and increasing productivity.
  • Dredging: Gravel and sand are commonly used in dredging operations to help maintain waterways and harbors. Dredging is the process of removing sediment and debris from the bottom of a body of water.
  • Mining: Gravel is often used in the mining industry as a component of the materials used to construct access roads, haul roads, and processing facilities.
  • Flood Control: Gravel is often used as a component of flood control systems to help protect against erosion and to slow the flow of water.
  • Environmental Remediation: Gravel is used in various environmental remediation projects such as stormwater management, wetland and stream restoration, or oil spill cleanup.
  • Marine Works: Gravel is frequently used in marine works such as the construction of breakwaters, jetties, and foundations of offshore structures. Pumping gravel allows the material to be placed quickly and efficiently in these applications
  • Transporting Sand, Gravel, Chat, and Aggregate*
  • Sumps

*Fluid Required – Seems obvious, but our pumps do NOT pump dry sand. No pumps do.

What Are The Problems With Pumping Sand and Gravel?

Sand and gravel aggregate pits are usually dredged using draglines or excavators to mechanically dig up the sand or gravel, then place it into large piles to await transport and processing.  The sand and aggregate are then loaded into large dump trucks and driven to the processing plant. This is a very costly and time-consuming process that incorporates very costly equipment and manpower.

EDDY Pump has developed various ways to avoid all these headaches and instead pump the sand and aggregate directly from the pit into the processing plant.  This can potentially save the plant millions of dollars a year.

Pumping sand and gravel can be a challenging task because these materials are typically abrasive and dense, which can become suspended in the fluid being pumped, which can cause blockages and clogs in the pump and pipelines. This can lead to reduced efficiency and increased downtime for maintenance and repairs.

Another problem with pumping sand and gravel is that it can be difficult to maintain a consistent flow rate. These materials can settle out of suspension and clog pipelines, which can restrict flow and cause pressure changes in the pump. This can lead to uneven and unpredictable pumping, which can make it difficult to achieve desired flow rates.

Also, Some sand and gravel pumps are not suited for the heavy-duty work that is needed for this application and these pumps may wear down prematurely or have reduced pump efficiency.

Additionally, sand and gravel can be highly corrosive, which can cause damage to the pump and other equipment over time. This can increase the frequency of repairs and maintenance, and ultimately reduce the lifespan of the equipment.

Finally, environmentally, if the process is not managed properly, it can cause negative impact on environment, such as damage to natural habitats, and also the sedimentation of nearby bodies of water.

The EDDY Pump’s unique design allows sand and gravel mines to pump the material at production rates of up to 450 cubic yards or 800 tons of material per hour.  Due to the EDDY Pump design allowing it to pump higher solids content, the processing plants will be dealing with significantly less water.  On average the EDDY Pump will handle about 40-70% solids by weight.  The EDDY Pump’s open rotor design also allows the pump to pump rocks up to 9-inch in diameter without clogging.  For operations where the plants prefer to screen down the aggregate size, classifiers can also be added at the front of the pump eliminating oversized rocks.

The best EDDY Pump dredges for the sand and gravel mining industry are the Excavator Pump Attachment, Remote-Operate Dredge, and Cable Deployed Dredge Pump.

Sumps in the sand and gravel industry play a crucial component in collecting all the sand, chat, rocks, and debris that are cast out during the processing. All these rocks, debris and abrasive material cause constant issues for centrifugal sump pumps. This means constant downtime and costly repairs. These abrasive sands quickly wear out the impellers of the pumps, in addition to the and the rocks and debris clogging the low tolerance centrifugal pumps.

The EDDY Pump is the ideal solution for these sand and gravel sumps and can be deployed electrically, hydraulically or self-priming.  The EDDY Pump will not wear out like the conventional centrifugal sumps pumps and will also not clog like the other sump pumps. All of these attributes about the EDDY Pump Sump pump mean a lot less down time and costly repairs like centrifugal sump pumps.
