In a submersible motor pump in which the lower casing uses a vertically split type casing that does not require a manufacturing core, the intermediate casing is placed on the lower surface of the intermediate casing corresponding to the upper casing. In order to shield the bolt part attached to the motor from water flow,
A submersible motor pump characterized by a replaceable ring made of a wear-resistant elastic material such as rubber. 2. By providing an O-ring-shaped protrusion on the inner diameter side of the elastic body ring, providing an annular groove that fits with the protrusion on the intermediate casing side, and forcibly fitting these protrusions and grooves, the above-mentioned elastic body Claim 1 characterized in that the ring is fixed to the intermediate casing.
Submersible motor pump as described. 3 The relationship between the inner diameter d 1 of the elastic ring, the outer diameter d 2 , the outer diameter D 2 of the impeller, and the blade width B 2 is expressed as 0.8D 2 ≦d 1 <d 2 ≦1.2×(D 2 +2
The submersible motor pump according to claim 1, characterized in that: B2 ). 4. The submersible motor pump according to claim 1, wherein the volute drainage portion of the lower casing is pressed down by an elastic ring. 5 A fitting part corresponding to the outer circumference of the elastic ring whose inner diameter side is forcibly fitted into the intermediate casing,
3. The submersible motor pump according to claim 1, wherein the submersible motor pump is provided in the lower casing to facilitate positioning of the intermediate casing and the lower casing. 6. The submersible motor pump according to any one of claims 1 to 5, characterized in that a tapered chamfer is provided in a portion of the outer peripheral portion of the elastic ring that fits into the lower casing.
