The present invention relates to a foreign object crusher with both replaceable sides for crushing a foreign object included in a taken fluid and a pump having the same. The foreign object crusher with both replaceable sides according to an embodiment of the present invention comprises: an intake cover installed in an intake through which a fluid is taken in, having a cutter mounting recess formed at the center thereof, and having a plurality of intake holes through which the fluid is taken in through the cutter mounting recess; a cutter member mounted on the cutter mounting recess, rotated by a driving motor, and having a plurality of wing parts radially disposed around a driving shaft of the driving motor to crush a foreign object through interaction with the intake cover; and a cutter cap overlapping an outer surface of the cutter member and formed to have an area decreasing in a direction opposite to a direction in which the fluid is taken in to allow the fluid to be easily introduced through the intake hole. Thus, since both sides of the cutter member are used, maintenance cost for replacement can be reduced, and since a foreign object is crushed by one surface of the cutter member and a circumference thereof, machinability can be enhanced. In addition, since the intake holes are maximized, an intake amount of the pump can be increased. |
