1. A pump comprising:
a housing having a suction chamber and a discharge chamber formed therein;
a suction part extending outwardly from a circumferential surface of the housing, and having a suction passage formed therein through which a fluid is introduced into the suction chamber;
a discharge part disposed under the suction part, extending from the circumferential surface of the housing in a direction opposite to the suction part, and having a discharge passage formed therein through which the fluid is discharged from the discharge chamber;
a partition wall dividing the suction chamber and the discharge chamber, and having a communication hole formed at a center thereof for allowing the suction chamber to communicate with the discharge chamber;
an impact body disposed toward the suction part so as to come into contact with the fluid introduced into the suction chamber through the suction passage; and
a gas discharge part disposed at an upper portion of the circumferential surface of the housing and communicating with an outside so that gas, separated from the fluid in contact with the impact body, is discharged,
wherein the suction part extends in one direction perpendicular to a virtual center line passing through the housing, and the impact body is disposed in a direction opposite to an extending direction of the suction part with respect to the virtual center line.
