Abstract: A magnetic levitated pump that does not cause pulsation of a pumped liquid and can suppress the generation of particles, which are liable to be produced by contact of a sliding part, is disclosed. The magnetic levitated pump for magnetically levitating an impeller housed in a pump casing includes a motor configured to rotate the impeller, and an electromagnet configured to magnetically support the impeller. The motor and the electromagnet are arranged so as to face each other across the impeller, and the motor is arranged on the opposite side of a suction port of the pump casing.
