Claims

[Claims for Utility Model Registration] (1) A pump drive body having a rotational drive means;
The gear pump unit includes a pump head having a suction port and a discharge port, and a gear pump unit assembled between the pump drive body and the pump head, and the gear pump unit includes a drive gear and a driven gear that mesh with each other, and a drive gear and a driven gear that mesh with each other. a gear casing that partitions a pump chamber for accommodating the gears and is open at both ends; and a first shaft that corresponds to the pump drive body when assembled. and a second side plate corresponding to the pump head, and a fixing means for fixing these plates integrally with the gear casing by bringing these plates into contact with the corresponding open end surface of the gear casing in a liquid-tight state, A drive connection portion extending through a first side plate is provided at one end of the gear to be operatively connected to the rotational drive means, and a second opening is provided that communicates the suction port and the discharge port with the pump chamber of the gear pump unit. A gear pump characterized by having a side plate formed with. (2) The fixing means consists of a stepped pin consisting of a large-diameter shaft portion inserted into the gear casing and small-diameter step portions formed at both ends of the large-diameter shaft portion, and the stepped pin is A gear pump according to claim 1, wherein a small-diameter stepped portion is inserted into and fixed to a corresponding side plate, and a large-diameter shaft portion defines an interval between both side plates.
