PROBLEM TO BE SOLVED: To provide a hollow shaft pump effectively functioning in agitating, lifting and transferring of sludge, and capable of being heightened in lift. SOLUTION: A plurality of liquid transferring structures 1A, 1B equipped with a liquid transferring means are arranged in series in the inner periphery of a hollow shaft 3 fitted in a stator 2, a suction cover 11 is installed in the front face of the liquid transferring structure 1A at the forward end, and a discharge cover 13 is installed in the rear of the the liquid transferring structure 1B at the forward end. The liquid transferring means 4a in the liquid transferring structure 1A at the forward end is excellent in the agitating function, and the liquid transferring means 4b in the succeeding liquid transferring structure 1B is excellent in the passage pumping function.
