NOVELTY - The pump has a pump cylinder, an outlet elbow, an impeller, loudspeaker opening and an impeller chamber such that the cylinder, outlet elbow and loudspeaker opening are made of graphene fiber/carbon fiber composite fiber material. The graphene fiber and carbon fiber composite ratio is 1 is to 1 to 3 is to 1. The pump cylinder, the outlet elbow and the loudspeaker opening are made of composite fiber by a fiber winding molding process. USE - Seawater pump. ADVANTAGE - The strength of metal components is improved, while corrosion resistance is lower than metal components, to realize seabed.
