A Liqui-Mover performs the same liquid transport functions as vane or centrifugal pumps. But since the Liqui-Mover is based on an entirely different operating concept, it has fewer moving parts than conventional pumps. As a positive displacement pressure-powered pump, the Liqui-Mover has no motors, starters, shafts rotating mechanical seals or impellers. Instead, the Liqui-Mover uses steam (or any compatible inert gas) under pressure as the motive force to lift or pump liquids.
