Abstract (en)
[origin: EP3913228A1] A pump unit (4), which is a non-positive displacement type pump provided in a liquid supply device (1), has a first seal section (66) and a second seal section (67) provided between an intake port (53) and a discharge port (48) in the circumferential direction of an impeller (40). An angle between the two straight lines connecting the circumferential ends of each seal portion (66, 67) and the center of rotation of the impeller (40) is 43° or more and 47° or less. Each seal portion (66, 67) has a size making it possible to close at least two through flow paths (63) between both ends in the circumferential direction.
