Abstract
A volute portion of a casing in a magnetic levitation type pump has a top wall, a bottom wall, and a circumferential wall. The top wall has a radially inner wall portion that is placed with a gap on one side in an axial direction with respect to an impeller, and a radially outer wall portion that is placed on an outer side in a radial direction with respect to the impeller. A volute flow path in which a transport fluid that has flowed out from the impeller flows is formed between the impeller and the circumferential wall and between the radially outer wall portion and the bottom wall in the volute portion so as to communicate with the gap. At least a part of the radially outer wall portion extends from a radially outer end of the radially inner wall portion toward the one side in the axial direction.
