Product Description
Mechanical seal for containerized reactors; highly adaptable, easy to install, and with stable and reliable performance; this seal is a typical structure for vertical large-diameter reactors with pressure ≤2.5MPa.
Product Features：Back-to-back mounting;Double-end face;Large shaft diameter;Assembled design;Self-adjusting bearing;Center-side stationary ring limiting.
- ouble-end face sealing structure, high safety
Utilizing a double-end face sealing design, combined with an isolation fluid system (PLAN53 series or PLAN54), a double sealing barrier is formed, effectively preventing media leakage, especially suitable for toxic, flammable, and volatile conditions.
- Back-to-back mounting method
The sealing end faces are arranged back-to-back, capable of withstanding bidirectional pressure, improving sealing stability, and adapting to pressure fluctuations under complex process conditions.
- Strong adaptability to large shaft diameters
Specifically designed for vertical large-diameter reactors, with strong structural rigidity, stable operation, and meeting the sealing requirements of large equipment.
- Assembled (Containerized) Structure Design
Utilizes a containerized mechanical seal, pre-assembled and adjusted at the factory, simplifying on-site installation, reducing human error, and improving assembly efficiency.
- Self-Adjusting Bearing Structure
Built-in self-adjusting bearings or compensation mechanisms automatically adapt to shaft runout and vibration, reducing sealing surface wear and extending service life.
- Center-Side Static Ring Limiting Design
Effectively controls the position of the sealing element through a static ring limiting structure, preventing movement and improving the reliability and stability of seal operation.
- Wide Operating Condition Adaptability
Temperature Range: -40℃～260℃ (depending on material selection)
Pressure Range: -0.1～2.5MPa
Speed: ≤300RPM
Capable of meeting various reaction process requirements.
- Multiple Flushing/Isolation Schemes Supported
