A single-axis eccentric screw pump is provided with: a stator 9 having an inner surface formed in a female screw-thread shape; a rotor 10 capable of being inserted through the stator 9 and comprising a shaft body having a male screw-thread shape; an outer cover body 8 capable of moving between a first position which is on the outer peripheral side of the stator 9 and a second position at which the outer cover body 8 compresses the stator 9; and a movement means 7 for moving the outer cover body 8 between the first position and the second position. As a result of this configuration, the contact pressure of the stator 9 on the rotor 10 is stabilized, and fluid is discharged at a desired discharge pressure. |
