Abstract
This circulation device is equipped with a water impeller that is larger than and tightly fitted over the top of the draft tube through which the water from the pond or reservoir is drawn. By placing the impeller above and out of the draft tube it enables to lift water through the draft tube and imparts a centrifugal force on the water above the impeller which aids in moving the water radially outward from the impeller. The water is directed outwardly over a large diffuser plate that is centrally located. The outer edge of the diffuser plate is equipped with a laminar flow diffuser lip which is designed to inhibit the passage of water from the diffuser plate to the open water. This design ensures that most of the energy imparted to the water by the impeller is retained once it leaves the diffuser plate, making the invention operate efficiently.
