Title:
磁気駆動ポンプ
Document Type and Number:
Japanese Patent JP5796095
Kind Code:
B2
Abstract:
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.
