ABSTRACT:
A component assembly is provided for converting a conventional centrifugal pump, of the vortex impeller type for example, to a different type of centrifugal pump, such as a spiral impeller pump. The component assembly enables a resident centrifugal pump to be converted to a more efficient or appropriate type of industrial pump when conditions or application processing requirements change, and avoids the need to entirely replace an installed pump for a new type of pump.
