Sulzer APP Pumps for Paper Mills, Mechanical Seals for Water Pumps
Introduction
1. The adoption of a modular double-ended mechanical seal not only simplifies on-site installation and replacement procedures but also effectively balances pressure across the sealing faces. This ensures the seal maintains exceptional performance even under elevated medium pressures.
2. The seal's rotating and stationary rings (friction pair) utilise high-performance materials such as silicon carbide. These materials possess high hardness and outstanding wear resistance, effectively handling minute solid particles within the medium. Concurrently, their excellent chemical stability and corrosion resistance enable adaptation to a broader spectrum of chemical media.
Features
The sealing's core friction pair end faces undergo super-finishing to achieve a mirror-like finish, thereby reducing the coefficient of friction and energy consumption while enhancing sealing performance and durability. All metal components (such as bushings and gland covers) are typically fabricated from high-grade stainless steel and may undergo surface passivation treatment to enhance corrosion resistance in humid and corrosive environments.
The combination of bellows and spring design ensures superior retention of the compensating ring's contact and tracking capability, enhancing the seal's adaptability to shaft vibration and axial movement (shaft play) for more reliable operation. Through its dual-balanced structure, premium friction pair materials, and precision manufacturing processes, it demonstrates comprehensive advantages in reliability, durability, and ease of maintenance. It effectively enhances pump set operational efficiency while significantly reducing unplanned downtime and maintenance costs caused by seal failure.
