Vacuum Pump Mechanical Seal Manufacturer
Precision-engineered seals for vacuum pumps — designed for leak-free, oil-free, and high-vacuum performance.
Why Mechanical Seals for Vacuum Pumps?
Vacuum pumps must maintain high vacuum levels and zero leakage during operation.
Traditional packing or oil seals are prone to failure under low-pressure, dry-running conditions, leading to vacuum loss or contamination. Mechanical seals effectively prevent air ingress and media leakage through high-precision face-to-face contact and wear-resistant, self-lubricating materials, ensuring long-term stable operation of vacuum systems.
Sakowit vacuum pump mechanical seals are specifically engineered for vacuum and dry systems, delivering reliable, clean, and low-maintenance sealing solutions.

Key Features & Benefits of Vacuum Pump Mechanical Seals
Sakowit vacuum pump mechanical seals prioritize “high sealing integrity, extended service life, and low energy consumption.” They ensure safe, reliable, and stable operation of vacuum systems.
- Prevents air ingress and media leakage: Operating in negative pressure environments, mechanical seals effectively block external air from entering the system.
- Suitable for high vacuum and slight positive pressure conditions: Utilizing a balanced design, it maintains uniform pressure across sealing surfaces under both high vacuum and slight positive pressure.
- Available in single-face or double-face configurations
- High sealing performance with minimal leakage: High-precision ground sealing surfaces (Ra ≤ 0.2 µm) achieve near-zero leakage (<500 ppm), meeting environmental and cleanliness requirements.
- High operational efficiency with low energy consumption: Low friction at sealing surfaces (μ≈0.03) reduces shaft power loss and enhances vacuum efficiency.
