Patent ID: 7097433

Claim:
A pumping assembly for removing a combustible liquid contained within a storage container comprising: a) a fluid transfer pump comprising: an intake having an opening; a pump/motor chamber having a fluid-cooled motor and a pump contained therein, the pump/motor chamber having an inlet, and an outlet to an air bell chamber; the air bell chamber having an air bell chamber outlet port; an electrical junction box to connect power wires to the motor; a pump chamber outlet connected to the air bell chamber; a foot valve connected to a riser pipe positioned between the intake and the pump/motor chamber that only permits fluid flow in the direction of the pump/motor chamber; wherein the pump/motor chamber is connected to the air bell chamber permitting the fuel to flow from the pump/motor chamber to the air bell chamber; wherein the air bell chamber outlet port is connected to the pump chamber outlet permitting the fuel to flow to the air bell chamber; and wherein the air bell chamber outlet port is connected to the storage container permitting the fluid to flow from the air bell chamber outlet port to the storage container; b) the storage container including a bung; wherein the fluid transfer pump is connected to the bung of the storage container to form a leak resistant fit and removably joined to the storage container to permit the riser pipe to pass through; c) a fluid contained within the storage container; wherein electricity flows from the power wires to activate the motor passing through the electrical junction box; wherein the motor activates the pump; wherein the pump activation draws the fluid i) from the storage container; ii) then through the foot valve; iii) then through the riser pipe; iv) then into the pump/motor chamber; and v) then into the air bell chamber; wherein the fluid may flow i) through the pump whereupon the liquid is pushed out the air bell chamber outlet port; or ii) through the path between the air bell chamber outlet port and the storage container.
