Meaning and Definition
A pump that lifts fluid by injecting air or gas into a submerged vertical pipe, creating a mixture of air and fluid that rises due to reduced density.
A simple, reliable pump with no moving parts in the pumped fluid, often used for pumping abrasive or corrosive liquids, or in situations requiring low maintenance and high reliability, such as in aquaculture, sewage treatment, or mining.
