Mechanical seals Type 186K

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.

  • 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
