The invention discloses a method for manufacturing a fluorine-containing dilute sulphuric acid delivery pump. The method comprises the following steps: a volute of a centrifugal pump is manufactured through 0.8mm graphite raw materials performed with twice dipping and triple baking and then is performed with triple immersion treatment and thermal treatment through phenolic resins; an impeller of the centrifugal pump is manufactured by 0.25mm high-quality graphite blocks and then is performed with triple dipping treatment and thermal treatment through the phenolic resins; and two mechanically-sealed end faces of the centrifugal pump are made of pressureless sintered silicon carbide. Products manufactured through the method are good in anti-corrosion performance, high in temperature resistance, stable in operation and long in service life.
