Seals for rotating shafts

SDF320 CEMA

The STASSKOL SDF320 is a cost-effective solution for applications that need a high-performing seal. This design eliminates major issues experienced by conventional soft packings, such as heat generation and leaking due to shaft runout, resulting in a long service life.
STASSKOL offers standard CEMA mounting options, making it suitable for a variety of applications, including screw conveyors, bucket elevators, drag conveyors, and bearing mounted applications if required. The SDF 320 is available with a split housing and as a cup housing version, providing versatility to meet your specific needs.

SDF320 CEMA Design

Design

With its two rotating seal rings, the SDF 320 shaft seal forms an axial seal against the housing’s running surfaces. An elastomeric sealing element connects the shaft to the sealing rings to prevent contact between them and the shaft thus protecting the shaft from wear. These non-contacting sealing rings allow for shaft runout without losing the seal on the shaft.
SDF320 CEMA Applications

Applications

The SDF 320 shaft seal, designed to seal with buffer gases, ensure safety in your operations. The sealing compounds, specifically tailored to seal against various media, including explosive dust, powders, liquids, slurries, and vapors, guarantee the seal’s long service life. STASSKOL even offers FDA-approved compounds if required by the application, further enhancing safety. The SDF’s proven design has demonstrated its reliability in challenging applications for mixers, blenders, augers, bucket elevators, drag conveyors, and screw conveyors.

Type overview

The SDF 320, a shaft seal design with a split housing and split sealing rings is a solution for applications that lack access to slide the seal assembly on the end of the shaft. The split design, which conveniently eliminates the need to remove bearings, couplings, motors, and other accessories, saves significant time and cost associated with traditional seal installations.

The SDF 320c, a non-split housing design, is a cost-effective solution for applications that need a high-performing seal with access to slide the seal assembly on the end of the shaft. This design can be supplied with non-split sealing rings to reduce cost or split rings for easy field service and replacement.
