PURPOSE: A non-seal magnetic driving gear pump is provided to arrange a gasket in the interface between a first housing unit and a housing cover which are joined to each other so that an end clearance between a driving gear rotor and a housing cover is determined by the gasket. CONSTITUTION: A non-seal magnetic driving gear pump includes a first housing unit(10) and a second housing unit which are connected to each other by a connecting casing. A driving gear rotor(40) is arranged inside the first housing unit. An idle gear(50) is arranged inside the driving gear rotor so that the center of the rotation of the idle gear is arranged eccentric from the center of rotation of the driving gear rotor. A bypass hole(16) is punched in a lateral side of an outlet(14) of the first housing. Some of fluid discharging through the outlet is supplied to between a driven magnetic rotor and a canister(90) through the bypass hole so that the driven magnetic rotor is cooled by the fluid. A hollow portion(62) is formed in a first shaft(60) so that the fluid filled with the fluid is discharged to the first housing unit through the hollow portion. |
