Slurry Eductors for transporting Sand Slurry through pipelines

Coastal Dredging and Oil Production from oil Sands are diverse applications but they have one thing in common – transporting sand slurry through pipelines.
In Coastal Dredging excavated sand slurry is transported to alternate disposal sites and in Oil production, Oil sands are transported to production plant.
In both applications the quantity of sand to be transported is considerable and hence sand is transported in form of slurry through pipelines.

For transporting through pipelines it need to be pump the pumping has to overcome below challenges
• Abrasive Media
• High Viscosity
• Presence of Solid Particles

Slurry Eductors are essentially liquid Eductors that utilize pumped water for operation.
During operation Slurry Eductors create vacuum at their suction inlet and this vacuum is put to use in sucking sand slurry inside the Eductor.

Once sucked the Slurry Eductor mixes sand slurry with water inside the Eductor. The mixture of sand slurry and Water is then pumped out from the Eductor outlet.
Thus the Slurry Eductor also acts as pump and can develop significant head at the outlet This enables the Sand Slurry to be pumped out from deep pits and to transport it over long distances.

The Slurry Eductor is designed to have replaceable internals and wear resistant materials are used for manufacturing these internals. This helps to obtain a long operating life from the Slurry Eductor.

Slurry Eductors are perfectly suited for transporting Sand Slurry because of their inherent characteristics.
• Performs dual function of mixing Sand with water and pumping the Sand Slurry.
• Eductors do not contain any moving parts and have large internal passage areas, hence are not vulnerable to clogging by solid particles.
• As they have no moving parts, maintenance requirements are very less. Also it reduces largely the risk of abrupt breakdowns, helps in maintaining the regular production schedule
• Service Water is a commonly available utility and hence no additional infrastructure is typically required.
