More Information
Summary:A water pump includes an impeller (17) provided on an end of a rotational shaft (14) supported on a body (11) through a bearing (13), a mechanical seal (18) provided between the impeller and the bearing, a draining hole (22) guiding a coolant leaked from the impeller side to a reservoir (28) provided at a bottom of the body via the mechanical seal, a vapor outlet (24) provided above the reservoir for establishing communication between the reservoir and the atmosphere, and the draining hole opening to the reservoir at a lower level than the vapor outlet. An axis of the reservoir is offset from a vertical plane which passes through an axis of the rotational shaft.
