Liquid jet solids ejector

A liquid motive medium is used to convey solids. The solids are either introduced via a funnel or they can also be sucked in. A carrier medium e.g. water or air is mixed in to improve the delivery effect. The Sand and Mud Eductor differ from standard eductors as they have an open suction port which is designed to be submerged in the material being handled, this allows the eductor to entrain relatively large solids and particles that would otherwise block a conventional eductor. Another feature of this unit are the agitating jets installed at the base of the eductor, these nozzles help to stir the material surrounding the eductor and make it fluid. This effectively means the eductor can be left buried in mud or slurry, and when operated it will begin to excavate the surrounding solids and begin pumping. Sizes are available in 1 Inch through to 6 Inch, with sizes up to 4 Inch supplied with screwed connections as standard, for sizes above 4 Inch connections are flanged are usually supplied. Typical materials of construction are Cast Iron, Carbon Steel, Stainless Steel and Bronze, however other materials are available on request.

Advantages

• Low Cost
• No Moving Parts
• Self Priming
• Corrosion and Erosion resistant
• Simple & reliable
• Automatic control as option
• Practically no maintainence during its service if “washed down” periodically
• Safe & Easy to install

Applications

Liquid jet solids pumps are used to convey sand, gravel, salt, activated carbon, ion exchange resin, and other types of solids; to fill and empty reactors with reactor mass or marble gravel in decarbonizing and deacidifying plants of water and effluent treatment plants; to add precipitating agents in dirty water and effluent water treatment.

Water treatment

• conveying filter materials such as activated carbon, gravel, exchange resins.
• conveying lignite dust in activated sludge.

Ship-building

• pumping water/solids mixtures out of the deep.
• laying of marine cables.
• conveying ash/air mixtures from incineration systems on passenger ships.
