▪ SEALS PACKAGE: The seals package prevents leakage of slurry into the motor and bearings. The shaft sleeve is made of corrosion and abrasion resistant material. ▪ SHAFT SLEEVE : Its function is to protect the shaft. The shaft has Heavy-duty roller bearings that prevent its displacement in other directions and reduce vibration. ▪ SHAFT AND BEARING ASSEMBLY : The shaft is used to transmit the rotatory movement from the motor to the impeller. It is normally made of cast iron, but depending of the application could come with protective anti-corrosion coating, or could be made in special alloys for abrasive applications. ▪ CASING : The casing shape is generally of semi-volute or concentric. The impeller could be closed, semi-open, open or recessed. Usually made of High-chrome spheroidal alloy that is very abrasion resistant. It transfers the centrifugal force to the sand. ▪ IMPELLER : The impeller is the rotating component of the submersible sand dredging pump. They could include also high temperature and /or moisture sensors. For Heavy duty electric sand submersible pumps is recommended to have a motor with Class H insulation. If the sand pump works semi-submerged or if it is going to work dry for extended periods of time, it should include a cooling jacket.
The cooling of the electric submersible sand dredging pump is important. ▪ MOTOR : Could be electric or hydraulic. Here below you can read about some of the multiple applications of sand pumps.
There are many applications for submersible sand pumps: sand and gravel extraction, dredging of rivers, harbors and marines maintenance or construction, beach reclamation, filling of Geotubes, among others. The mixture of liquid and particles of sand and gravel is pumped in a procedure often used as a convenient way of handling sand and gravel. Sand is pumped mixed with water up to 70% of solids by weight. Hydroman™ TSQ Submersible Sand Dredging Pumps are suitable to be used for pumping sand.
