Transvac’s ejectors provide a method of pumping and pressure boosting of sand slurry entrained from separators. With no moving parts and no maintenance, they are increasingly being used instead of mechanical pumps, the company said. The ejectors use the energy available from high-pressure motive liquid (such as produced water) to entrain sand slurry from a separator, and pump and pressure boost the resulting mixture to a cyclone separator or scrubbing system. The ejectors are also used as flushing devices and to dilute sand slurry to improve slurry transportation.
