DEPAC seal type 270 is a stationary design cartridge mounted single mechanical seal. It has been developed for simple and easy change from packings to mechanical seals without modifications of the existing equipment. The stationary design principle developed by DEPAC for the process industry ensures highest reliability and smooth running even in difficult seal applications.

Advantages

  • Stationary design
  • Simple change from packings to mechanical seals possible
  • Best suited for standardization
  • Cartridge mounted
  • Pressure balanced
  • Direction of rotation independent
  • Multiple spring design and springs made of Hastelloy C
  • No fretting of shaft
  • No clogging of springs
  • .“ NPT axial flush and quench connection (up to O 70 mm | 2 3/8“)

Technical specifications

Operating range*

  • Pressure: 700 mm Hg up to 28 bar
  • Temperature: depending on Elastomer
  • Sliding velocity: up to 35 m/s

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.
