<p>The present invention relates to a fluid metering pump for continuously transferring the certain quantity of fluid. And the present invention comprises: a ring-shaped pump housing (200a) having an inlet (201) and an outlet (202) in which a pipe of the waste water is combined to enable to be watertight; a radial support drum (210) in which a mount edge (120a) of a semicircular elastic tube is sealed in the edge and which is bonded to the inner diameter of the ring-shaped pump housing (200a) in order to be connected to the inlet and the outlet; an axle supporter (230) combined in the side of the radial support drum (210) to include an axle mount (232) extended to the elastic tube in order to restrict the axial expansion of the elastic tube; a rotor retainer (220) including a rotor combining hole (221) bonded to the ring-shaped pump housing (200a) in the external side of the axle supporter (230); and a rotor (101) configured to support a squeeze roller (102) to rotate, wherein the squeeze roller (102) is connected to the elastic tube (120) to be compressed and rotatably coupled in the rotor combining hole (221).</p> |
