Abstract

PURPOSE: To lessen disassembly load at the time of assembly and disassembly of a large vertical pump with high specific speed and ensure thereby safety by mounting a casing liner surrounding the periphery of the impeller on the suction part formed solidly with the base construction and forming it separated from a guide vane drum.
CONSTITUTION: A casing liner 2 is fixed to the suction part 1 formed solidly with the base construction, being separated from a guide vane drum 4. The other is same as a conventional arrangement. Accordingly, only guide vane drum 4 and discharge bent 5 can be lifted up at the time of assembly and disassembly, so that disassembly load can be lessened. The rotary part is born as illustrated at this time, that will give good stability and safety.
