The origins of the Little Giant Pump Company date back to 1941, with the world's first "self-contained electric motor-driven submersible pump". Called "a submersible vaporizer," this unique, patented pump design became the cornerstone for hundreds of different pump models Little Giant manufactures and ships worldwide today. In fact, derivatives of that basic "self-contained electric motor-driven submersible pump" have become the standard for quality and reliability in water transfer applications throughout the world. The organization is headquartered in Oklahoma City, Oklahoma and has comprehensive product lines that are built by a knowledgeable and dedicated workforce. Little Giant operates out of an 180,000 square foot distribution center where they continue to bring you the latest technology with unparalleled customer service. Little Giant is a quality name you can trust and count on.
