Abstract

PURPOSE: To promptly discharge foreign matter entered in a liner space where an impeller directly faces a casing by providing a foreign matter guide channel in the liner space.
CONSTITUTION: When foreign matter enters a liner space 12 located between an impeller 3 and a casing 4, the foreign matter is transferred in the liner space 12 in circumferential directions by revolution of the impeller 3 and is trapped in a guide groove 14. The foreign matter is discharged into a water channel 6 by pressure differences between the inner and outer peripheral sides of the guide groove 14.
