Abstract
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.
