An underflow withdrawal device is described for use in connection with a thickener tank or other separation tank. The underflow withdrawal device includes an inducer which is positioned between the underflow outlet of a thickener tank and a centrifugal pump, and is positioned for contacting the underflow as it leaves the tank. The inducer shear thins the underflow to modify its flow characteristics, thereby increasing the flowability of the dense, thickened material through the centrifugal pump. The inducer is rotated by virtue of an extension of the drive shaft which operates the impeller of the pump. Therefore, the costs of manufacturing and operating the underflow withdrawal device are reduced. |
