PROBLEM TO BE SOLVED: To attain a modular formation of a vertical pump and make it adaptable for various kinds of containers. SOLUTION: A central part of a first bottom wall 2 is provided with a suction valve 7. A first circumferential wall 3 is raised from an outer circumference of the first bottom wall 2. A first outward flange 4 for use in installing a container body is arranged at an upper end of the first circumferential wall. There are provided a main body member 1 spaced apart between the member and the first circumferential wall 3 and raising a cylinder 5 from the first bottom wall 2; an operating member 20 having a discharging valve fitted in such a way that it can be moved up and down within the cylinder 5 and it can not be pulled away; and a compression coil spring 40 installed in the clearance for use in biasing upwardly the operating member 20 in respect to the main body member 1. Moving-up or moving-down operation of the operating member 20 in respect to the cylinder 5 enables the liquid sucked from the suction valve 7 into the cylinder 5 to be injected out of a nozzle port arranged at the upper part of the operating member 20 through a discharging valve. |
