A Liqui-Mover pump performs the same liquid transport functions as vane or centrifugal pumps. But since the Liqui-Mover pump is based on an entirely different operating concept, it has fewer moving parts than conventional pumps.
Since it is a positive displacement pressure-powered pump, the Liqui-Mover pump has no motors, starters, shafts rotating mechanical seals or impellers. Instead, the Liqui-Mover pump uses steam (or any compatible inert gas) under pressure as the motive force to lift or pump liquids.
With none of these maintenance-intensive components to leak, wear or fail, the Liqui-Mover pump is naturally more reliable than conventional pumps. Therefore, the Liqui-Mover pump will work longer, with less maintenance and far less downtime.

Fewer Operational Restrictions
Many conventional pumps have difficulty handling liquids with temperatures above 85°C (185°F), so coolers or flash tanks must be added to the system. Valuable steam is lost during the flashing process, while the extra cooling equipment increases both installation and operating costs, and further reduces system reliability.
However, Liqui-Mover pumps have few temperature restrictions. For most applications, no additional coolers or flash tanks are needed. Cooling losses from flashing condensate are minimized. The result is savings over other pump systems - in reduced capital and operating costs, in greater energy conservation, and in lower maintenance.
Also, since the Liqui-Mover pump has no impellers or rotors, it does not suffer from cavitation, which limits conventional pump performance.
Other Advantages
Due to their simple design and compact dimensions, Liqui-Mover pumps are easy to integrate into system designs - and they're equally easy to install.
Another advantage is liquid metering. Each Liqui-Mover pump discharges a fixed volume per cycle. So by counting the number of complete cycles, you can determine liquid volume pumped by the unit.
