How to Choose a sand pump

A sand pump is most commonly used for dredging,mining,desilting project to pump sand, sediment, and other material by pipe line.

how does sand pump work?

The basic structure of sand pump is composed of impeller, pump casing, shaft, bearing, bracket, shaft seal and other parts.
The power is generally connected to a motor, diesel engine, or hydraulic motor, which can be directly connected by a coupling, or connected by a pulley or a gearbox.
The working principle is that when the impeller runs fast, the blades of the impeller make the sand and water rotate quickly, and the rotating sand flies out of the impeller under the action of centrifugal force. After the liquid in the pump chamber is thrown out, the central part of the impeller forms a vacuum. In the area, under the action of atmospheric pressure or water pressure, the slurry is pressed into the sand discharge pipe through the pipe network, so that the continuous circulation can realize continuous sand suction。

Is there a pump that can pump sand?

Everflowing Sand pumps are an essential pump for dredging and mining operations. Everflowing sand pumps are large flow,highly efficient and reliable,They are used to move sand, slurry,gravel, and other materials long distance.

How to Choose a sand pump

When choosing a dredge pump, you should consider the following factors:

  1. Installation and Use Conditions: The conditions in which the pump will be installed and used will determine the type of pump required. Marine pumps are suitable for dredging in marine environments, while land pumps are used for dredging on land. Excavator pumps are specifically designed to be used with excavators. excavator dredge pump
  2. Pumping Medium: Consider the type of material you need to pump, such as river sand, sea sand, ore sand, slurry, mud, etc. Different pumps are designed to handle specific types of materials, so choose a pump that is suitable for your pumping medium.
  3. Power Source: Determine the power source for the pump based on the available options and requirements. You can choose between electric pumps, hydraulic pumps, or diesel engine pumps, depending on the specific situation and power availability.
  4. Solid Particle Size and Specific Gravity: Take into account the size and specific gravity of the solid particles in the material you need to pump. Some pumps are better suited for handling larger particles or materials with higher specific gravity.
  5. Operating Conditions: Consider the drawdown depth (the depth from which the material needs to be dredged), horizontal discharge distance, and any height differences that need to be overcome during pumping. These factors will help determine the pump’s capacity and required power.
  6. Pumping Capacity: Determine the desired pumping capacity, i.e., how many cubic meters of sediment you plan to pump per hour. This will help in selecting a pump that can handle the required volume efficiently.
  7. Pipeline Size: Consider the size of the pipeline through which the material will be transported. The pump should be compatible with the pipeline size to ensure smooth and efficient operation. flexible dredge hose

By considering these factors, you can make an informed decision when choosing a dredge pump that is most suitable for your specific dredging requirements.


What is sand concentration of sand pump?

Sand pump can handle up to 70% soild by weight.

How deep and far can sand be pumped with a sand pump?

Horziontal sand pump dredging depth up to 30m

Submersible sand pump dredging depth up to 40m-120m

Is there pump that can pump dry sand?

It can be pumped if mixed with water.

Sand pump need water to transfer sand.

Dry sand should be added water.Dry sand mixed with water to form a sand water mixture (about 70% water, 30% sand),then pumped by sand pump.
