Abstract
A submersible pump-motor assembly for use in dispensing petroleum from petroleum storage tanks. The pump-motor assembly of the present invention enhances the performance characteristics of the pump-motor assembly by providing greater flow area around the motor stator while maintaining the alignment of the assembly's critical pump components. Such enhanced pump performance characteristics provide the petroleum dispensing station manager using such pump-motor assemblies with greater flow rates per dispenser or, when maximum flow rates are capped, potentially greater dispensing capacity.
Claims24
A pump-motor assembly, comprising:
- a motor unit;
- a pump assembly having components;
- and
- a shell having an expanded portion, wherein the shell encloses the pump assembly components and the motor unit with the expanded portion disposed around the motor unit and wherein the shell aligns the pump assembly components to the motor unit.
A pump-manifold assembly, comprising:
- a manifold;
- a pump-motor assembly;
- and
- a piping assembly connecting the pump-motor assembly to the manifold,
- wherein the pump-motor assembly comprises:
- a motor unit;
- a pump assembly having components;
- and
- a shell having an expanded portion, wherein the shell encloses the pump assembly components and the motor unit with the expanded portion disposed around the motor unit and wherein the shell aligns the pump assembly components to the motor unit.
A petroleum distribution system for use in a petroleum dispensing station, comprising:
- a petroleum storage tank;
- a petroleum dispenser;
- a pump-manifold assembly, in fluid communication with the petroleum dispenser, having a pump-motor assembly, wherein the pump-motor assembly is disposed in the storage tank and the pump-motor assembly comprises:
- a motor unit;
- a pump assembly having components;
- and
- a shell having an expanded portion, wherein the shell encloses the pump assembly components and the motor unit with the expanded portion disposed around the motor unit and wherein the shell aligns the pump assembly components to the motor unit.
A method for increasing fluid dispensing flow rate in a petroleum distribution system for use in a petroleum dispensing station, comprising:
- providing a petroleum distribution system including a petroleum storage tank;
- a petroleum dispenser;
- a pump-manifold assembly, in fluid communication with the petroleum dispenser, having a pump-motor assembly, wherein the pump-motor assembly is disposed in the storage tank and the pump-motor assembly includes a motor unit, a pump assembly having components, and a shell having an expanded portion, wherein the shell encloses the pump assembly components and the motor unit with the expanded portion disposed around the motor unit and wherein the shell aligns the pump assembly components to the motor unit;
- and
- energizing the pump-motor assembly to pressurize the petroleum distribution system.
A method for increasing dispensing capacity in a petroleum distribution system for use in a petroleum dispensing station where the maximum dispensing flow rate is capped, comprising:
- providing a capped maximum dispensing flow rate;
- providing a petroleum distribution system including a petroleum storage tank;
- a petroleum dispenser;
- a pump-manifold assembly, in fluid communication with the petroleum dispenser, having a pump-motor assembly, wherein the pump-motor assembly is disposed in the storage tank and the pump-motor assembly includes a motor unit, a pump assembly having components, and a shell having an expanded portion, wherein the shell encloses the pump assembly components and the motor unit with the expanded portion disposed around the motor unit and wherein the shell aligns the pump assembly components to the motor unit;
- and
- energizing the pump-motor assembly to pressurize the petroleum distribution system.
