Abstract: A pump includes: a branch pipe extending from a pump body for branching a part of raw water introduced from outside through a raw water inlet; a first tank having an exhaust pipe of an engine accommodated therein, the raw water supplied via the branch pipe being evaporated by heat of the exhaust pipe; a second tank provided over the first tank and having the branch pipe accommodated therein, vapor produced by evaporation of the raw water in the first tank being condensed into water droplets in the second tank; and a communication pipe interconnecting the first and second tanks in communication with each other.
