Horizontal peeler centrifuge for chemical applications

A shaft seal that is preferably a radial shaft seal has a sealing element of polyfluorocarbon that is provided with a sealing lip. The sealing element contacts a surface to be sealed under a radial force action acting in a radial direction of the shaft seal. An elastomer element is provided that is acting on the sealing lip and loads the sealing lip in a direction toward the surface to be sealed. The elastomer element supports the sealing element. The sealing element is resting flat on a face of the elastomer element, wherein the face is facing away from a medium side of the shaft seal.

Shaft seal, especially radial shaft seal

A mechanical seal has a housing having a collecting space for a coolant/lubricant medium. A sleeve is disposed in the housing. A counter ring is disposed in the housing and fixedly connected to the sleeve. A slide ring is disposed in the housing and interacts with the counter ring. At least one inlet conduit communicating with the collecting space is provided. The at least one inlet conduit is positioned between a radial bottom of the housing and a radial ring segment of the sleeve.

Mechanical seal

Slide ring seals have the problem that they generate noise under certain conditions of use. In order to suppress this noise in an effective way, the slide ring seal has at least one damping part that comprises at least one shaped sheet metal part. It is provided with at least one elastically deformable spring part that is supported under pretension. Between the damping part and the support area microfriction is generated that leads to an effective noise damping action. The slide ring seal is advantageously used in the automotive field.
