Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a uniaxially eccentric screw pump for powder transfer with a powder transfer clogging means for preventing the clogging of a transfer pipe due to deposit of powder during transferring powder such as hydrated lime particularly easy to deposit. SOLUTION: One end of the transfer pipe 13 is connected to a powder discharge port 5a at the end of a stator 5 for the uniaxially eccentric screw pump 1 for powder transfer and a flexible wire 16 is rotatably inserted into the pipe 13 throughout its length. One end of the flexible wire 16 is locked to the end of the rotor 4 in an integrally rotatable manner and the flexible wire 16 is earthed via a pump casing 8 or a driver for the rotor 4.
