ることを特徴とするダイヤフラムポンプ。[Claims for Utility Model Registration] It has two diaphragms that face each other with a partition between them and are connected by a shaft that passes through the partition. The pump reciprocates, and the outer surfaces of both diaphragms suck in and push out fluid due to the reciprocating motion, and the seal mechanism is provided at a portion of the partition wall through which the shaft passes through to suppress leakage of the pressurized air. A diaphragm pump comprising an oil-impregnated silicon carbide push that is slidably fitted onto the shaft.
