The utility model relates to the technical field of closed pump filling devices, in particular to a closed pump filling device, which comprises a storage tank, a liquid inlet pipe arranged on the storage tank, two groups of fixing frames symmetrically arranged on the storage tank, an efflux pump connected with one end of the storage tank, a partition plate mechanism with partition and pressure reduction functions arranged in the storage tank, and a worm rotating to enable a worm gear to rotate. The worm wheel drives a first group of shafts II to rotate, the first group of shafts II drives a first group of driving levers to turn over, and the first group of driving levers enables the other two groups of driving levers to turn over together through two groups of connecting rods, so that three groups of partition plates are turned over simultaneously until the three groups of partition plates divide the interior of the storage tank into three groups of areas, and liquefied gas in liquid is distributed in the thr
