Fluid transfer pump and method of operation

A method of assembling a compact fluid transfer pump assembly comprising the steps of:

• providing a pump enclosure comprising a pump cavity sized to house a plurality of pump components, said pump enclosure having an inlet for receiving fluid and an outlet hose barb having an outlet for the passage of fluid, wherein fluid flows between said inlet and said outlet hose barb along a fluid flow path;
• providing a motor enclosure coupled to the pump enclosure, the motor enclosure comprising a circular first end spaced by a cylindrical wall having an inner and an outer surface to a circular second end, forming a motor enclosure cavity therebetween within said cylindrical wall, the circular first end having an opening for receiving a motor, the circular second end formed by a bell wall, the motor enclosure removably couplable with a tank;
• and
• providing an anti-rotation foot removably coupled with said motor enclosure and extending from said outer surface of said cylindrical wall of said motor enclosure, said anti-rotation foot comprising a plurality of elongated channels to assist in coupling said pump assembly with an external fluid reservoir, said anti-rotation foot having an integral connector mount extending from one of said plurality of said elongated channels.
