Claims

[Scope of utility model registration request]

Both suction pumps and a canned motor share a common rotation axis and are liquid-tightly integrated, and the canned motor is one of a pair of pump suction chambers formed between an outer casing and an inner casing of both suction pumps. A pressure chamber is provided adjacent to the pump suction chamber on the opposite side via a partition, and the tip of the rotary shaft is rotatably fitted to the partition via means of high flow resistance, and the pressure chamber A double suction canned motor pump, characterized in that the pump discharge side and the pump discharge side are connected through a fluid passage.
