Abstract: A rotary seal comprises includes a first annular element, a second annular element and a seal element. The first annular element has a first axially extending flange and a first radially extending flange extending radially from a proximal end of the first axially extending flange. The second annular element has a second axially extending flange and a second radially extending flange extending radially from a proximal end of the second axially extending flange in the same direction as the first radially extending flange. The second annular element is fixed to the first annular element, the second axially-extending flange being received radially on the first axially-extending flange. The second radially extending flange is spaced axially from the first radially extending flange to define a pocket therebetween.

Abstract: An agitator for being disposed in a container and rotated to agitate fluid in the container includes a shaft and an impeller attached thereto. The shaft, being supported relative to the container, provides an input for attachment of a rotation mechanism for causing rotation of the impeller and shaft. The impeller includes an impeller body defined by a hub portion for receiving and being mounted to the shaft, and a plurality of blades extending radially outwardly from a longitudinal axis of the hub portion. The impeller body is a single piece of unitary construction, such as where the plurality of blades are formed in a manner that the blades are integral with the hub portion at the formation of the blades.

Abstract: A method consistent with the present disclosure may include: (a) equalizing pressure between a nozzle inner void and a receptacle main inner void by pressing a nozzle check against a receptacle check to open the nozzle check and the receptacle check; (b) extending the nozzle into the receptacle such that a receptacle main body surrounds at least a portion of the nozzle probe; (c) flowing fluid from the nozzle inner void into the receptacle main inner void.

Abstract: An in-line connector is disclosed having a plurality of connector components attached in an in-line configuration with a common bore. Depending on the application, the in-line connector can have an end seal and a holding block for securing the in-line connector to a pin, lead, or shaft. The connector components are arranged so that at least one seal element is located between two adjacent conductive contact elements. To provided added biasing force to a seal lip of the at least one seal element, a seal groove is provided with an energizer located therein.

Abstract: A mechanical seal is disclosed having a rotatable sealing face and a stationary sealing face that are in opposed relation and arranged to be urged, into contact to form a seal. One of the sealing faces is mounted on a support assembly that includes a biasing device operative to move that sealing face into contact with the other sealing face. In one form of the invention, the biasing device includes one or more resilient members that in use are deformed to provide the biasing force. In a second form of the invention, the support assembly forms part of a fluid barrier of the seal and the biasing device is fluid impervious and forms part of the barrier. In a third form of the invention, the biasing device is exposed to fluid pressure in the chamber and the biasing force increases on increasing the fluid pressure in the chamber.

Abstract: The present invention relates to a new kind of a mechanical seal, a so called slide ring seal, which is used, for example, for sealing a shaft space of a centrifugal pump in relation to a pumping space thereof. The present invention especially relates both to centering said mechanical seal and/or fastening said mechanical seal to the casing of said centrifugal pump and a body part used for the attachment. A characterizing feature of a mechanical seal in accordance with the present invention, comprising at least one rotary slide ring unit (24, 24?, 24?), a body part by means of which said seal is attached to said casing (16), and at least one either separate counter ring unit (42, 42?) or a counter ring unit (42, 42?) stationarily attached to said body part, is that said body part (40, 40?) is provided with inclined fastening means (52), by means of which the body part (40, 40?) is tightened to the casing both axially and radially.

Abstract: A face seal device for use with components rotating at a high rotational speed includes a non-rotating face seal ring (5) and a rotary face seal ring (11). The rotary face seal ring is mounted in a loose fit for common rotation with a rotating component and includes a sealing face (6) which, in operation, is essentially radially aligned for cooperation with an opposite sealing face (16) of the non-rotating face seal ring. A heavy-mass-contributing element (22) is arranged to rotate in common with the rotating component and engages a portion of the rotary face seal ring. The center of gravity of the heavy-mass-contributing element is axially spaced from that of the rotary face seal ring, whereby, in operation, a torque directed towards the non-rotating face seal ring is applied to the rotary face seal ring. This torque arises from the centrifugal forces that correspond to the mass-contributing element and the spacing between the centers of gravity.
