(54) Pump unit and fluid supplying system


(57) A fuel supplying system includes a tank (11) and a pump unit (12), which transfers fluid from the tank (11). The pump unit (12) includes a first pump (P1), a second pump (P2), and a drive source (M) . The first pump (P1) and the second pump (P2) are driven by the common drive source (M). The first pump (P1), the second pump (P2), and the drive source (M) are structured as one unit. This reduces the size and simplifies the structure of the fuel supplying system.
