Hydroman® Submersible Slurry Dredging Pump For Sea Marine Work - China

Hydroman® Submersible Slurry Dredging Pump for Sea-Marine Work are suitable to be used for pumping sand.

Sand is pumped mixed with water up to 70% of solids by weight.

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.

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.

Here below you can read about some of the multiple applications of sand pumps.

Design Features: ▪ MOTOR: Could be electric or hydraulic.

The cooling of the electric submersible sand dredging pump is important.

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.

For Heavy duty electric sand submersible pumps is recommended to have a motor with Class H insulation.

They could include also high temperature and /or moisture sensors.

▪ IMPELLER: The impeller is the rotating component of the submersible sand dredging pump.

It transfers the centrifugal force to the sand.

Usually made of High-chrome spheroidal alloy that is very abrasion resistant.

The impeller could be closed, semi-open, open or recessed.

▪ CASING: The casing shape is generally of semi-volute or concentric.

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.

▪ SHAFT AND BEARING ASSEMBLY: The shaft is used to transmit the rotatory movement from the motor to the impeller.

The shaft has Heavy-duty roller bearings that prevent its displacement in other directions and reduce vibration.

▪ SHAFT SLEEVE: Its function is to protect the shaft.

The shaft sleeve is made of corrosion and abrasion resistant material.

▪ SEALS PACKAGE: The seals package prevents leakage of slurry into the motor and bearings.

The seal package could be composed of lip seals, mechanical seals or hybrid seals.

▪ UPPER AND LOWER WEAR PLATES: These plates are located over and below the impeller.

They are subject to wearing.

The calibration of their clearances maximizes the efficiency of the submersible sand dredging pump.

▪ STRAINER: the strainer prevents the entry of large particles that could get stuck inside the impeller zone causing damage to the pump.

▪ AGITATOR: Allows the pump to pick up sediments, putting solids on suspension.

The way it works, due to the design of the vanes, forces a continuous high pressure flow of liquid towards the sediments, this flow following the shape of a cone; transport the solids to the eye of the impeller achieving a high concentration of solids.

The agitator also prevents solids from blocking the holes of the strainer.
