This submersible ejector is composed of a BE/B
type pump and a venturi
with diffusor trumpet. The large flow from the pump, first, at high speed,
draws and mixes itself with air in the venturi, then in the diffusor changes into
a massive unidirectional horizontal stream of tiny bubbles with water or sludge.
The pump is of the non-clog single blade shaver type.
