Patent ID: 7232288

Claim:
An apparatus for providing a submersible pump, comprising: a) a housing having top and bottom ends and a side wall, an inlet being disposed in said bottom, and an outlet being disposed in said side wall of said housing, an inner chamber being disposed in said housing; b) a plurality of downwardly extending legs being disposed on said bottom of said housing so as to space said inlet away from the supporting ground; c) a hydraulic motor being disposed on said top of said housing, an output member being rotatably disposed on said hydraulic motor, a motor mount for mounting said motor to said housing, said motor mount having a plurality of first apertures therein; d) an impeller plate coupled to said output member of said hydraulic motor, said impeller plate having a plurality of second apertures therein, an impeller blade disposed on said impeller plate, said impeller plate and impeller blade being disposed in said inner chamber of said housing so that material can be pumped from said inlet to said outlet of said housing; e) an air passageway leading from said second apertures of said impeller plate to said first apertures of said motor mount so that trapped air can escape from said inner chamber of said housing to the atmosphere while the apparatus is operating; f) wherein said motor mount is a plate having top and bottom surfaces and a downwardly extending peripheral edge, wherein said first apertures extend substantially horizontally through said edge of said motor mount to the atmosphere; and g) wherein said top of said housing comprises a top plate, said top plate having top and bottom surfaces wherein said top surface of said top plate is oriented toward said bottom surface of said motor mount, said top plate having a centrally disposed third aperture therein, wherein said output member of said motor extends downwardly through said third aperture so that an opening is formed between said outer surface of said output member and said inner surface of said third aperture so that air can pass through said opening as the air travels from said second apertures to said first apertures to the atmosphere.
