Summary:The present invention relates to a shaft coupling (also referred to as a spacer coupling) that couples a motor shaft and a pump shaft while both shafts are spaced from each other. The present invention is further relates to a pump apparatus having such a shaft coupling. The shaft coupling (10) includes: a first inner circumferential surface (23) capable of contacting an outer circumferential surface of a motor shaft (6); a second inner circumferential surface (24) capable of contacting an outer circumferential surface of a pump shaft (1); a step portion (26) protruding radially inwardly from the first inner circumferential surface (23) and capable of contacting an end portion of the motor shaft (6); and a spacer portion (28) located between the step portion (26) and the second inner circumferential surface (24).
