In sand management applications, special consideration needs to be given to material choice. All of Transvac’s sand handling Ejectors are supplied with special-grade ceramic internal parts (nozzle and diffuser section) to resist abrasion. As a result, Transvac has never been required to supply replacement parts due to wear from sand or solids, learn more about Ejector Longevity.
The Ejectors are designed and manufactured in accordance with the client’s piping standards with typical materials including Super Duplex, Duplex & Carbon steel.
Transvac Sand Slurry Ejectors are an ideal method of transporting sand slurries from Separators or Cyclones as part of a de-sanding / sand washing system. Accumulated sand is normally fluidised to ensure it will flow, prior to entering the suction port of the Ejector. The motive fluid can be Produced Water or pressurised water sources.
Ejectors provide high-shear pumping, which can be used effectively in the sand cleaning process. Any oil which remains attached to the sand is successfully separated from it as it passes through the high-velocity section of the ejector. This is then pumped into the separator / cleaning vessel for continued processing.
Ejectors can be used to perform a number of duties in the oil flotation process. Transvac has developed a special ‘micro-bubble generating’ ejector device capable of producing ultra-fine bubbles. With a huge surface area created, a more efficient flotation process is observed. Where excess gas needs to be recovered from the flotation vessel, a second ejector is available to compress and recover this gas.

Transvac Ejectors can be used for a variety of Produced Water Treatment duties such as:
