A structure improvement of a pump casing with a Polyfluoroalkoxy (PFA) liner which improves manufacturing efficiency, reduces manufacturing cost and improves yield strength, more particular to keep the stiffness of the shaft support and improve yield of the pump casing. The metal pump casing with the PFA liner used for handling corrosive liquids includes a suction casing with PFA liner, and a volute casing with PFA liner for accommodating an impeller. The volute casing also collects and then ejects the liquid through a discharge. The suction casing with the PFA liner and the volute casing with the PFA liner are separately formed as two workpieces by injection molding process and then assembled to form the pump casing so as to reduce the residual stress applied in the PFA liner.
