| Zusammenfassung: | A water pump (
10
) and impeller (
30
) for use in applications such as internal combustion engines. A plurality of holes (
40, 44
) are formed near the hub and periphery of the impeller (
30
) of the water pump to provide coolant flow through a cavity (
22
) housing a seal. The seal (
18
) is thereby cooled to prevent premature failure of the seal (
18
) due to overheating. |
