<P>PROBLEM TO BE SOLVED: To provide a magnet coupling type uniaxial eccentric screw pump, which shortens a total length of the pump, and in which no centrifugal load unnecessary for a drive shaft acts on. <P>SOLUTION: The uniaxial eccentric screw pump 1 includes: a screw pump 40; a casing 30 connected to the suction side of the screw pump 40 and having a suction port 135 on the side surface; and an under-water bearing 20 and the magnet coupling 10 connected to the casing 30 sequentially from the opposite side of the pump 40. The screw pump 10 has: a rotatably pivoted stator 41; and a rotor 42 connected directly to the drive shaft 8, and the rotary axial line L2 of the rotar 42 is arranged eccentrically from that L1 of the stator 11 by a predetermined distance E. <P>COPYRIGHT: (C)2013,JPO&INPIT |
