    摘要： The disclosure offers a sealless magnetic drive pump for improving the stiffness of a stationary shaft (3), and more particularly to, a metal magnetic drive pump with an anti-corrosion casing liner (4a). The magnetic drive pump is used in manufacture processes related to corrosive fluid. The pump is especially used in a highly corrosive and high-temperature (up to 200°C) condition to improve the stiffness of a front support. The stationary shaft includes a metal front support (43) integrated with the pump casing (4) at a pump inlet (44) and encapsulated with a resin enclosure made of a fluoropolymer; a rear shaft seat (413) positioned on a sealed bottom side of a containment shell (41) for offering auxiliary support for the stationary shaft (3); an impeller (5) including a channel for reducing an inlet flow velocity to offer a low NPSHr.

    摘要： A structure improvement of a pump casing (4) 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 (4) with the PFA liner used for handling corrosive liquids includes a suction casing (41) with PFA liner, and a volute casing (42) with PFA liner for accommodating an impeller. The volute casing also collects and then ejects the liquid through a discharge (422). The suction casing (41) with the PFA liner and the volute casing (42) with the PFA liner are separately formed as two workpieces by injection molding process and then assembled to form the pump casing (4) so as to reduce the residual stress applied in the PFA liner.
