WATER PUMP AND IMPELLER THEREFOR |
摘要 |
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.
