摘要： A centrifugal pump of the chopper type is disclosed which is structured with a chopper plate and impeller that are configured with an open eye or “hubless” arrangement such that processing of solids through the pump does not result in clogging of solids at or near the center of the impeller, thereby producing a dead zone. Because the configuration of the chopper pump of the present invention avoids the development of a central dead zone or clogging of solids, and provides for flow of solids and fluid through the eye of the impeller, pump efficiencies are markedly improved.

摘要： Axial adjustment apparatus is provided in a centrifugal pump to effect adjustment of the impeller relative to adjacent pump elements. Specifically preferred is adjustment apparatus in a chopper pump that provides adjustment of the impeller relative to a chopper plate to facilitate continuous efficient cutting of solids by the pump. The adjustment apparatus may also include adjustment structure for providing axial adjustment between the impeller and a plate-like member positioned adjacent the drive side of the impeller to effect adjustment of cutting tolerances in cutting elements positioned between the impeller and plate-like member. The invention further includes a seal mechanism configured and positioned to retain the seal height of the seals throughout continuous adjustment of the impeller.

摘要： 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.
