<p>A centrifugal pump comprises a pump body (24) defining a pump chamber (3), an electric motor (4) having a housing and a drive shaft (5), an impeller (6) which is mounted on the shaft (5) inside the chamber (3), a first plate (14) which is joined to the pump body (24) and the motor housing, and a second plate (15) which separates the chamber (3) from the motor (4). To prevent the radially inner periphery of the second plate (15) being displaced by pressure inside the chamber (3), the first plate (14) has a portion (20) supporting the second plate (15).</p> |
