A sand pump is a unit used most commonly in oilfield and land-moving applications. A sand pump is generally the primary means of moving solid matter from one place to another in the most efficient means possible. Sand pumps work through a process called centrifugal motion. This means a sand pump may also be classified as a centrifugal pump.

 

Sand pumps work through the use of a textured or grooved disc. The disc is rotated around a central axis, creating a force of movement through the grooved disc’s rotation. The action forces the movement of any material that comes into contact with the grooved disc, because of the draw/release action created by the movement of the grooves.

 

A sand pump can be used in a number of different instances and move a number of different substances, but they are referred to as sand pumps because they are most often used to move sand deposits from one point to another. Sand pumps are generally placed in fluid or oil tanks that have sunken or become filled with sand, and then move sand through a series of pipes and junctions. They may possibly even move sand through other pumps that may be incorporated to maintain the material pressure through the entirety of the system.
