[0002] The horizontal corrosion-resistant pump is a pump device with horizontal structure and corrosion resistance. The pump shaft is horizontally installed, the motor and the pump body are in the same horizontal plane, the center of gravity is low, the operation is stable, and the installation and maintenance are convenient.
