Summary:PROBLEM TO BE SOLVED: To maintain a pumping volume, which is not inferior to the pumping volume due to a pumping action of a protruding structure of a guide vane as compared to the initial condition even in the abrasion case of the protruding structures, in the stable condition efficiently and to get it persistent. SOLUTION: An impeller which is easily mounted in a built-in shaft of the sealing device of the prior art and equipped with a number of vane protrusions, rotating together with the shaft, is provided in the built-in shaft portion of sealing device and the sealing device of the prior art is transformed into a volute pump.
