Patent ID: 7341436

Claim:
An open face cooling system for cooling a motor of a motorized, impeller-type, submersible pump operated in a host fluid ladened with solids, comprising: a cooling system inlet in a pump housing of said pump proximate an impeller and spaced apart from the axis of said pump such that vanes on said impeller sweep a face of said inlet with a shearing motion, thereby reducing the size of such solids as are present at said face of said inlet and forcing said fluid ladened with solids into said inlet, a cooling system distributor further comprising an open face toroidal section with an adjoined lower distribution section, said cooling system distributor being configured co-axially around and above said motor, and a cooling system conduit connecting said inlet to a tangentially oriented nozzle incorporated in said open face toroidal section of said distributor, whereby said solids ladened fluid forced by fluid pressure within said pump into said inlet, flow through said cooling system conduit into said cooling system distributor with a circular flow, and discharges therefrom onto said motor.
