This disclosure relates to an improved vertical type uniaxial eccentric screw pump for transferring a variety of powders such as flour, cement and pigment. The vertical type uniaxial eccentric screw pump, without jetting compressed air inside the pump, directly sucks powder contained in a vessel through a suction port in the lower end of the pump and transfers the powder to any desired place. An eccentric screw pump includes a stator and a rotor, and a propeller shaft projects from the lower end of the male thread type rotor. Vanes for sucking powder are mounted on the shaft, and a powder delivery port is formed in the pump casing close to the discharge port at the upper end of the stator.
