PURPOSE: An underwater motor pump with an adjustable wear ring is provided to prevent the lifespan of a motor from becoming reduced by preventing noise and damage to a bearing. CONSTITUTION: An underwater motor pump(1) with an adjustable wear ring comprises a pump unit(2), an electric motor unit(3), a chamber unit(4), an impeller(25), and a variable wear ring. The pump unit and the electric motor unit are integrally assembled by the same driving shaft(10). The chamber unit is mounted on the upper end of the electric motor unit. Water from the lower part is pumped to the upper part while the impeller of the pump unit operates by the operation of the electric motor unit. The variable wear ring is installed between an upper casing(21) and a lower casing(22) on the pump unit.
