Abstract
An improved liquid pump for transporting live fish or other products in an induced flow has secondary line with one end to be placed in a pool of liquid containing fish or other products. The other end of the line is connected to a housing having an internal pump chamber. A primary intake has one end connected to a reservoir of liquid and the other end connected to the housing concentrically about the secondary line. As liquid flows through the primary intake into the pump chamber and out the outlet, the Coanda effect results in a low pressure area in the pump chamber. The liquid in the secondary line is induced to fill the low pressure area. By shaping and directing the primary intake and the secondary intake within the pump chamber a more efficient pump is produced.
