Title (EN) CUTTING ASSEMBLY FOR A CHOPPER PUMP
(FR) ENSEMBLE DE COUPE POUR UNE POMPE HACHEUSE
Abstract:
(EN) Embodiments of the invention provide a cutting assembly for a chopper pump. The cutting assembly includes a cutting insert having a cutting blade extending radially therefrom, and an impeller having; a central hub, a plurality of vanes and an insert surface. The insert surface defines an axial recess that is dimensioned to receive the cutting insert therein. The cutting assembly further includes a cutting plate having a plate hub with a cutting extension protruding radially inward therefrom. Rotation of the impeller rotates the cutting blade past the cutting extension.
(FR) Selon des modes de réalisation, l'invention porte sur un ensemble de coupe pour une pompe hacheuse L'ensemble de coupe comprend une plaquette de coupe ayant une lame de coupe s'étendant radialement à partir de celle-ci, et une roue ayant : un moyeu central, une pluralité d'aubes et une surface de plaquette. La surface de plaquette délimite un évidement axial qui est dimensionné pour recevoir la plaquette de coupe. L'ensemble de coupe comprend en outre une plaque de coupe ayant un moyeu de plaque avec une extension de coupe faisant saillie radialement vers l'intérieur à partir de celle-ci. La rotation de la roue fait tourner la lame de coupe au-delà de l'extension de coupe.
