摘要: A seal for use in a centrifugal pump, the pump having a stationary pump casing, a stationary plate and an axially adjustable side liner, is disclosed. The seal includes a base having an inner surface and an outer surface. A band portion extends from the base and a retainer member extends from the band portion. The retainer member is spaced apart from the base and oriented for positioning against a groove formed in the axially adjustable side plate liner of the centrifugal pump.

摘要: A sealless magnetic drive pump features in improving the stiffness of a stationary shaft. More particularly, the metal magnetic drive pump has an anti-corrosion casing liner. 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 integrated with the pump casing at a pump inlet and encapsulated with a resin enclosure made of a fluoropolymer; a rear shaft seat positioned on a sealed bottom side of a containment shell for offering auxiliary support for the stationary shaft; an impeller including a channel for reducing an inlet flow velocity to offer a low NPSHr.

摘要: A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.

摘要: A double seal pump assembly is provided and comprises a pump housing having an inlet and an outlet. An impeller is in communication with the inlet and outlet. The impeller includes an impeller shaft extending outwardly from the housing. The impeller shaft is adapted to engage a drive shaft of a motor. A housing adapter is mounted onto the housing at a first seal and is configured to secure the impeller to the housing. A motor adapter is mounted to the housing adapter at a second seal thereby defining a cavity therebetween. The motor adapter is configured to mount the motor and the cavity is configured to be filled with a barrier fluid. An accumulator is in fluid communication with the cavity and is adapted to hold a reserve barrier fluid so as to maintain barrier fluid volume and pressure within the cavity.

摘要: Various “contactless” bearing mechanisms including hydrodynamic and magnetic bearings are provided for a rotary pump as alternatives to mechanical contact bearings. In one embodiment, a pump apparatus includes a pump housing defining a pumping chamber. The housing has a spindle extending into the pumping chanber. A spindle magnet assembly includes first and second magnets disposed within the spindle. The first and second magnets are arranged proximate each other with their respective magnetic vectors opposing each other. The lack of mechanical contact bearings enables longer life pump operation and less damage to working fluids such as blood.
