Pumping Solids & Slurries
Using a liquid or air to entrain solids & slurries
Hopper Eductors
The Hopper Eductor is a hopper equipped jet ejector designed to entrain and mix granular solids or slurries with liquid and discharge the mixture to a receptacle or transfer it to a desired location. Originally developed to mix drilling mud for oil industry applications, these devices have proved to be so effective and versatile that they are being applied in increasing numbers in diverse industries including the food, chemical processing, pharmaceutical, glass, water treatment, and power to name but a few. Hopper Eductors are also used extensively for ejecting sludge's from tank bottoms, for pumping sand from filter beds and for washing and conveying granular materials.

Hopper Eductors are also used extensively for ejecting sludge's from tank bottoms, for pumping sand from filter beds and for washing and conveying granular materials.
Typical materials handled can be borax, charcoal, diatomaceous earth, lime, mash, fly ash, rosin, rock, activated carbon powder, granulated salt, sand, dry sawdust, light soda ash, dry sodium nitrate, powdered sulfur, wheat and many others.
Optional wash down nozzles can also be mounted at the top of the hopper to help prevent the material from adhering to the sides of the hopper by continually wetting the walls, this also helps to more easily move the materials down in to the eductor. Wash down nozzle are particularly effective when the material easily bridges or if a large quantity of material is being added, and can also help to reduce dust clouds forming when used with fine powders.
Hopper eductors are manufactured in a variety of types and sizes as well as materials, our standard Type 267 and 254 range in size from 0.75 Inch to 6 Inch, where as the Type 242 Hopper Eductors can range from 0.75 Inch up to and beyond 24 Inch. Variables such as pressure, temperature, density, required entrainment rates, and operating conditions must all be considered before determining the correct type and size of eductor to best suit to your requirements. Material of construction is typically Stainless Steel or Carbon Steel, however we can manufacture from practically any workable material. Also depending up on the application we can apply ceramic inserts or hardened coatings to the internal bores to extend service life for aggressive and erosive materials.
Sand and Mud Eductors
The Sand and Mud Eductors are recommended for use in pumping out wells, bore holes, pits, tanks, sumps and similar containers where there is an accumulation of sand, mud, slime or other material of a nature not easily handled by the standard eductors.
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.
Air Jet Syphons
Air Jet Syphons operate on the jet principle utilising the energy of gas under pressure to pump and handle solids and slurries. Any air or gas source can be used to drive the syphon whether it be supplied from a compressor, gas bottle and in certain applications blowers may also be used.
Due to the simplicity of design and lack of moving parts syphons are well suited to handling powders, ganulated solids and slurries. However consideration should be given to the solids being handled as significant errosion can take place if the solids are particluarly abrasive. Where necessary ceramic internals or hard linings can be fitted to help prevent errosion and extend working life.
Syphons are easy to install and they may be located in remote and inaccessible places without requiring constant attention.
