What is a jet siphon used for?

Syphons can utilize any type of condensable vapor but non condensable, dry-air motivated units are not generally recommended due to potential air/water hammer inside the syphon. This equipment is primarily used to pump sumps but can be designed to drain any vessel while transporting a process liquid.
