PURPOSE:To set arrangement of the pump in the title into a composition suitable to a simple and economical inspection and maintenance by fitting and mounting a rear cover member, a guide impeller member, a front plate member and an impeller in a casing part through a cylindrical or conical fitting surface. CONSTITUTION:A pump driving essential part comprising a rear cover member 3 which is coaxial with a prime mover part 8 and integrally linked and fixed thereto, a front plate member 5 including a guide blade member 4 and a fixed side wearing member and an impeller 6 surrounded by the abovementioned members and fitted around a main shaft 7, is fitted in an attached to casing members 1, and 2 through cylindrical or conical fitting surface parts 1a, 3a and conical fitting surface parts 2b, 5b. Thus, it is so composed that a series of maintenance main parts may be fitted and removed in an approximately one touch back and pull-out process. Therefore, a rational and economically excellent practical effect can be obtained in the entire process such as design plan, execution of manufacturing, operational maintenance management or the like concerning the pump equipments.
