The upper casing has an inlet and an outlet, the upper casing is fixed on the bottom casing, and the impeller is arranged between the upper casing and the skived fin cooling plate. In addition, the skived fin cooling plate is fixed on the bottom casing, and the impeller sucks the heat-dissipating liquid from the inlet and drives the heat-dissipating liquid passing through the skived fin cooling plate, upwardly passing through the impeller and then discharged from the outlet.

A pump includes a housing which forms a suction chamber and a discharge chamber therein; a suction nozzle which is disposed in one side of the housing, and communicates with the suction chamber; a discharge nozzle which is disposed in the other side of the housing, and communicates with the discharge chamber; a partition wall which partitions the suction chamber and the discharge chamber, and has a communication hole, which communicates the suction chamber and the discharge chamber, that is formed at a central portion; and a plurality of baffles which are disposed inside the suction chamber, and guide fluid introduced through the suction nozzle to the communication hole, wherein the plurality of baffles have different lengths and are separated apart from each other in a circumferential direction in an upper side of the partition wall.

The invention relates to the field of pump design. A multistage centrifugal pump with two parallel flows of pumped medium comprises a housing consisting of two separate parts, each of which contains impellers and guide apparatus, and a central pressure cover mounted between said parts of the housing. A delivery pipe is vertical and centrally oriented. The pump additionally includes an end transfer cover for transferring fluid from the first part of the housing to the second part via transfer channels provided integrally with the pressure cover and the transfer cover. The impellers are arranged in the first and second parts of the housing such as to be opposed to one another in relation to the central pressure cover. The first part of the housing comprises a horizontal suction pipe and a vertical discharge pipe, which are disposed on the drive side of the pump and are configured in the form of a single cast part. The discharge pipe is connected by a transfer pipe to an annular chamber in the central pressure cover.
