  • Patent number: 9028209
    Abstract: A pipeline pump shaped by stamping and welding, comprises a pump body, a pedestal, a pump rear cover and a motor installed at the opening of the pump body, and an impeller arranged inside the pump body. The pump body is comprised of an inner cylinder and an outer cylinder. A flow guide part, the impeller, an exhaust part, and the pump rear cover mounted on the opening of the outer cylinder are coaxially arranged upwards in turn from the opening of the inner cylinder. The impeller is axial suction and radial discharge. The disk bottom of the flow guide part is sealed with the opening of the inner cylinder. The impeller is coaxially arranged inside the flow guide part, and a flow guide vanes corresponding to a radial exhaust port of the impeller are provided on a circumferential wall of the flow guide part.
