スシール型モータポンプ。[Claims for Utility Model Registration] A gas seal chamber is airtightly integrated above the pump section, and a rotary shaft, which is sealed with a mechanical seal and projects above the gas seal chamber, is connected to the motor section. In the motor pump, an auxiliary pump chamber is provided between the pump section and the gas seal chamber, and a shaft penetration gap between the rotating shaft and a partition that partitions the auxiliary pump chamber and the gas seal chamber. An auxiliary pump part is constructed by disposing an auxiliary impeller with the suction side facing toward the auxiliary pump chamber, and a plurality of auxiliary impellers that communicate between the protruding side of the auxiliary pump part and the outer diameter side of the gas seal chamber. A gas seal type motor pump, characterized in that a pump outlet hole is formed in the partition body.
