摘要： A method of fabricating a pump casing that includes an inlet, an outlet and a pump casing body. The pump casing body has a neck portion that defines a groove. The inlet is formed by stamping a sheet of metal to form a basin-shaped body, wherein the stamping the center portion of the basin-shaped body forms the inlet. Centering the basin-shaped body about a first axis and using one set of roller dies to roll form the basin-shaped body into a pump casing body. The pump casing body includes, starting from the inlet, an inlet end plate, a passage side plate, a motor end plate and a neck portion. Stamping the passage side plate forms the outlet. A set of roller dies include an internal roller die and a mating external roller die, wherein both are rotatably mounted along a second and third axes, respectively, wherein the first, second and third axes are parallel to but spaced from each other.
