ABSTRACT:
A centrifugal blood pump has an impeller with a hub, a blade support ring and alternating long and short blades. A tapered seal between a pump housing wall and a hub of an impeller which provides a fluid tight seal interface surrounding a shaft. The long blades of the impeller have rear edges which are closer to the wall than is the seal interface and inner edges which extend from the rear edges to the hub. This provides high flow in the vicinity of the seal interface to enhance heat dissipation from the seal interface.
