たことを特徴とするサブマージドポンプ装置。 In a submerged pump device, the submerged pump device includes a casing incorporating a drive device, a drive shaft extending from the drive device through the inside of the casing and protruding downward from the casing, and a pump driven by the drive shaft. A sealing mechanism between the casing and the outer circumference of the drive shaft is provided below the bearing of the drive shaft, and the seal mechanism includes a primary seal as a mechanical seal for sealing lubricating oil of the bearing. In addition, an inner mechanical seal and an outer mechanical seal are disposed below the primary seal between the rotating body integrated with the drive shaft and the fixed member on the casing side, and these inner mechanical seals are disposed below the primary seal. A secondary seal is provided between the seal and the outer mechanical seal, which is supplied with oil and subjected to a constant static pressure, and is composed of a seal oil circulation mechanism connected to an oil cooler, and is provided below the secondary seal. 1. A submerged pump device comprising a cargo liquid seal consisting of a labyrinth seal and a non-contact centrifugal pump type dynamic seal provided below the labyrinth seal.
