Mechanical seals

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.

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
