<p>PURPOSE: To improve a pumping performance of a pump which has a fluidized impeller that can rotate freely around a rotary axis matching with an inlet by adding a self-feeding device to feed a suspension directly to an impeller-blade for a fluidization of the fluidized impeller. CONSTITUTION: A pump supports a hollow shaft 14 which has a plurality of slender slots 15, 16 in a main housing 11 that has an inlet 12 and an outlet 13 for a suspension of a pulp and so forth rotatably. And a fluidized impeller which has a plurality of impeller blades (vane) 18 that consists of the first part 19 which is parallel to a center of axis A generally and the second part 20 that changes a direction at a central part gradually and crosses at a right angle toward the center of axis A generally. A boat-shaped propeller 24 which has a vane 25 as a self-feeding device which feeds the suspension to the vane 18 is provided at the shaft 14 and an nonrotary device 33 which has a stator- vane 34 is provided around the propeller 24.</p> |
