Sludge Eductors for pumping Mud through pipelines

Large scale excavation in Infrastructure & Construction Projects requires the excavated mud to be transported to an alternate area or disposal sites. Typically the mud is extracted from the bottom of the excavation pit and brought to surface for further transportation.

For large project the quantity of excavated mud is considerable and transporting it through pipeline is the convenient option. For deep excavation lifting the mud from the bottom of the pit o the surface is a big challenge.

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

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

Sludge Eductors for Mud Pumping applications are designed in a special manner which allows them to be lowered into pits, while the water pumps stay on the surface.

The Sludge 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 Sludge Eductor.

Sludge Eductors are perfectly suited for transporting Mud because of their inherent characteristics
• Performs dual function of mixing Mud with water and pumping the Mud Sludge
• 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.
