The AK59B is a hydraulically balanced multispring DIN 24960 seal giving low face loading at high
pressures.
General chemical applications, oil refining, petrochemical, and pharmaceutical industries.
Suitable for use with corrosive fluids and for cryogenic and high-temperature applications.
By choosing suitable component materials, the seals can be adapted to operate with a wide range of liquids and operating conditions.
Structure Description:
Equivalent to Jonhncrane 59B
Multiple spring , balanced seal
Features
- Complies with European Standard EN 12756, formally DIN 24960/L1K, ISO 3069 and API 610 specification for the petrochemical industry.
