摘要： Disclosed is a submerged motor pump of the type in which a motor is installed inside an outer casing so as to define an annular passage therebetween and a pumped liquid is discharged to the outside through the annular passage while cooling the entire periphery of the motor. The outer casing is formed using a resilient material and is retained at its upper and lower ends by rigid members. Accordingly, the outer casing is deformable in the radial direction so as to absorb external force, for example, impact force, which may be applied thereto during transportation.

摘要： A submergible motor pump including a vortex impeller attached to an end of a motor shaft, a pump casing attached to a motor casing and accommodating the impeller therein, a strainer attached to the pump casing for introducing water to be sucked into the pump casing, and a bottom plate supporting the strainer from therebelow is disclosed. The pump casing comprises an intermediate casing member and a lower casing member, which are detachable from each other. The pump casing has a configuration in which the upper side is open so that the flow passage formed in the lower casing member does not have a bag-shaped configuration. A plurality of legs are provided on the lower side of the lower casing member as being integral portions thereof. The legs are spaced apart from each other and extend as far as the outer peripheral end of the lower casing member. The strainer is provided around the outer peripheral end of the lower casing member in such a manner as to surround the outer periphery of the lower casing member. The lower casing member is clamped betwen the bottom plate and the intermediate casing member by means of clamping bolts, thereby assembling together the bottom plate, the lower casing member and the strainer in one unit.

摘要： A motor pump group has a plurality of centrifugal pumps of the same nominal port diameter including a plurality of impellers having stepwise greater outside diameters for stepwise higher pump heads, and a plurality of respective motors for actuating the pumps. The pump heads are classified into a low head section and a high head section. The low head section is handled by a single-stage impeller, and the high head section is handled by multi-stage impellers. The centrifugal pumps have respective pressed-sheet pump casings. The outside diameters of the impellers are not required to be increased in the high head section, and the outside diameters of the pump casings fall in a relatively small range.
