PROBLEM TO BE SOLVED: To provide a uniaxial eccentric screw pump capable of smoothly transferring liquid objects which have a wide temperature range from high temperature to low temperature or have low viscosity to high viscosity, having high discharge performance, enabling stable use for a long time, having a simple structure and capable of reducing the entire weight. SOLUTION: In this uniaxial eccentric screw pump 1, a stator 5 with a female threaded hole 7 having an oval opening cross section and spirally continuing in the longitudinal direction is formed of a rigid resin material, and a male thread shaped rotor 3 is loosely inserted into the female threaded hole 7 of the stator 5, leaving a slight clearance. An end stud 15 is arranged in one end open side of the stator 5, and a tip part of a pump casing 16 connecting the other end open side of the stator 5 and the end stud 15 are connected and fastened by a plurality of staybolts 19. Due to this constitution, both stator 5 and end stud 15 are connected integrally with the pump casing 16. COPYRIGHT: (C)2006,JPO&NCIPI
