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.

A method of manufacturing a component includes additively manufacturing a crucible; directionally solidifying a metal material within the crucible; and removing the crucible to reveal the component. A component for a gas turbine engine includes a directionally solidified metal material component, the directionally solidified metal material component having been additively manufactured of a metal material concurrently with a core, the metal material having been remelted and directionally solidified.

Two hybrid ball bearings and a compressor bearing arrangement with two hybrid ball bearings for a rotatable support of a rotor of the compressor versus a stator of the compressor. The two hybrid ball bearings are arranged face-to-face or back-to-back, are designed with an optimal axial clearance depending on the inner diameter of a ring-shaped inner raceway element one of the hybrid ball bearings respectively a pitch diameter of one of the two hybrid ball bearings for a long bearing life in connection with an optimal compressor operating performance.

Molten metal transfer pump, in which a shaft (4) with the impeller (5) mounted on the shaft (4) is installed on the upper bearing (2) and the lower journal plain bearing (3). The lower journal plain bearing (3) has rotor (15) and stator (16) parts. The rotor part (15) is made in the form of two split bushings (17) mounted on the shaft (4), and the stator part (16) is made in the form of two split bushings (18) fixed in the cage (19) in axial alignment with the shaft (4). Bushings (17) (18) are fixed correspondingly with flat rings (24) (33) and composed of cylinder segments (20), (28) equidistantly placed in a circumferential direction, located correspondingly in the cylindrical groove (21) on the shaft and cylindrical groove (29) of the cage (19) and fixed with cone hold-down rings (22), (30) radially, and with spring rings (23), (31) axially.

Embodiments of the invention are directed to a rotor for use in molten metal and devices including the rotor. The rotor has a rotor body and blades, wherein each blade includes a tip that is at least twice as hard as the rotor body.

A hydraulic machine includes a first member (1) having a first structure (2) for a hydraulic medium opening in a first interface surface (3) and a second member having a second structure for the hydraulic medium opening in a second interface surface is described, the first interface surface (3) being in contact with the second interface surface, wherein at least one of the members (1) is provided with a support element (6) surrounding the member (1). Such a machine should have a good efficiency. To this end the support element (6) has a strength varying in circumferential direction around the member (1) and/or in thickness direction in a middle region of the member (1).

The present invention is directed to a spa tub (and to a spa chair that includes a spa tub) that has a sprayer with a thermal meter so that an employee does not need to touch or feel the water and/or fluids to gauge the temperature of the water and/or fluids. The spa tub may also have a water pump and/or an air pump assembly that is designed and configured to be mounted to the wall of a basin for providing massage therapy to a user. In addition, the spa tub may additionally have a liner and/or an air dispenser. As a non-limiting embodiment, a spa chair includes a spa tub, a basin, a mounting housing member, and a sprayer with a thermal meter. The spa chair may also include a jet assembly, an air pump assembly a spa base, a gasket or seal, an air dispenser, and/or a liner.

A fluid pump for dispensing a fluid to a setting or work environment is disclosed. A fluid pump having a contactless, fluid sensor and for use with a liner is also disclosed. The pump includes a jet assembly, a motor assembly, and a contactless, fluid sensor. The pump may further include a mounting housing member, a gasket or seal, and a liner when a liner is not already present. The jet assembly is coupled to or secured about the motor assembly. The jet assembly includes a jet assembly housing, and preferably also includes a printed circuit board (PCB), a PCB cover, a shaft assembly, and an impeller. The jet assembly housing includes a base, a top cover, an impeller-receiving chamber, at least one inlet aperture, and at least one outlet aperture. A pump apparatus that includes a pump as described, a power source, and/or a control apparatus is further disclosed.
