DEPAC component seal style 186K is a dynamic single seal which has been developed especially to replace common elastomeric bellows seals. This seal type fits to installation spaces according to DIN 24960 / EN 12756 but is designed with a shorter installation length.

Style 186K can be combined with all common stationary seats.

This seal is characterized by universal application opportunities and is suitable for many different sectors of industry.

Advantages

  • Replaces common component seals with short installation length
  • Axial and radial mounting possibility
  • Short installation length
  • Pressure balanced
  • Direction of rotation independent
  • Multiple spring design and springs made of Hastelloy C
  • No fretting of shaft
  • No clogging of springs
  • Can be combined with various stationary seats

Technical specification

Operating range*

  • Pressure: 700 mm Hg up to 30 bar
  • Temperature: depending on Elastomer
  • Sliding velocity: up to 30 m/s
  • Shaft movements:
    • ​axial ≤ O 60 +/- 0,5 mm | > O 60 +/- 1,5 mm
    • radial ≤ O 60 +/- 0,5 mm | > O 60 +/- 1,0 mm

Maximum temperature / pressure / speed indicates operating extremes independently and does not imply the seal will function at these extremes at the same time. Contact Pactor if in doubt.
