<P>PROBLEM TO BE SOLVED: To provide a pump apparatus with a crushing function and a fluid supply system by which the amount of waste to be trapped can extremely be reduced, a filter exchange service life can extremely be extended and operation cost can significantly be reduced. Ž<P>SOLUTION: The pump apparatus with a crushing function for forcibly feeding fluid containing solid components is configured such that a suction space 15, a discharge space 17 and a pair of engaging gears 11 and 13 are provided in a casing 10, the fluid sucked into the suction space 15 is confined between the outer peripheral part of the gears 11 and 13 and the casing 10 and forcibly fed to the discharge space 17 by the rotation of the pair of engaging gears 11 and 13, the solid component in the fluid staying in the discharge space 17 is pulled into the engaging part 30 of the gears by the rotation of the pair of engaging gears 11 and 13, crushed, turned to solids of a small particle size and returned to the suction space 15, the solids and the sucked fluid are mixed in the suction space 15, confined again between the casing 10 and the gears 11 and 13 and forcibly fed to the discharge space 17.
