PURPOSE: A pumping equipment of a liquid storage vessel is provided to save production costs due to simple structure of the vessel, and to prevent the content of the vessel from going bad by removing an air layer inside the vessel. CONSTITUTION: A pumping equipment of a liquid storage vessel includes a vessel(100) in which an accept rib(111) having a separation-preventing protrusion(111a) capable of preventing separation of a pumping head(10) is integrally formed on the top of the body with the lower part open, and a vacuum maintenance portion(200) which discharges the air inside the body into the outside and keeps the vacuum condition while pressing into the content filled in the body of the vessel. |
