Abstract

Provided is a cascade pump device which can reduce installation space. The cascade pump device (1) may include a pump chamber (25), an impeller (21), a magnetic drive mechanism structured to rotate a coil (27), and a pump case (2) installed with the above components. The pump case (2) is provided with two end faces (2a,2b) located at both ends in an axial line direction and an intermediate part (2z) between the two end faces. The intermediate part (2z) is provided with a suction pipe (3) and a discharge pipe (4) and a wiring outlet part (6) for taking out wiring lines (5) for supplying an exciting current to a drive coil of a motor. The suction pipe and the discharge pipe are protruded in the same direction and the wiring outlet part is provided with a wiring line drawing-out guide part (6a) which determines a drawing-out direction (D1) of the wiring lines to the outer side. An angle between the drawing-out direction (D1) and a protruding direction of the suction pipe and the discharge pipe is less than 90 DEG around the axial line.

Description

technical field

[0001] The present invention relates to a cascade pump device with a structure in which a suction pipe and a discharge pipe communicated with a pump chamber protrude parallel to each other from the side of a pump casing. Background technique

[0002] A cascade pump device for pressurized liquid transfer called a vortex pump or a cascade pump is described in Patent Document 1. The cascade pump device of the above document includes a pump chamber, an impeller, a magnetic drive mechanism that drives the impeller to rotate by exciting a drive coil, and a pump housing in which they are installed. The pump casing has a flat cylindrical shape, and a suction pipe and a discharge pipe communicating with the pump chamber protrude parallel to each other from the side of the pump casing. In the above document, the magnetic drive mechanism is a motor, and a cable for supplying an exciting current to a drive coil of the motor is drawn out radially outward from the lower e...
