Abstract

A uniaxial eccentric screw pump comprising: a stator (9) having an inner peripheral surface on which female threads are formed; and a rotor (10) being insertable into the stator (9) and formed of a male-threaded shaft body, wherein the uniaxial eccentric screw pump further includes: an exterior body (8) configured to be movable between a first position on an outer peripheral side of the stator (9) and a second position where the exterior body (8) compresses the stator (9); and a moving means (7) configured to move the exterior body (8) between the first position and the second position. With such a configuration, a contact pressure applied to the rotor (10) by the stator (9) is made stable, and a fluid material is discharged at a desired pressure.
