1. Reliable Sealing: Extremely low leakage (≈1% of soft packing seals); stable performance during long-term operation.
2. Long Service Life: 1–2 years in oil/water media, ≥6 months in chemical media.
3. Low Friction Loss: Friction power consumption is only 10%–50% of soft packing seals.
4. Minimal Shaft Wear: Shaft/sleeve remains almost unworn.
5. Long Maintenance Intervals: Automatic wear compensation; no frequent maintenance needed.
6. Good Vibration Resistance: Insensitive to shaft vibration, runout, or seal cavity misalignment.
7. Wide Application Range: Suitable for high/low temperature, high pressure, vacuum, and corrosive/abrasive media.
8. Adaptability to Twin-Screw Pumps: Matches screw pump characteristics (stable flow, low pulsation); compatible with non-lubricating/viscous media.
Precautions for Use
Installation
1. Alignment & Concentricity:
◦ Tighten gland bolts evenly after coupling alignment; face runout ≤0.05 mm.
◦ Gland-to-shaft/sleeve clearance uniform; concentricity tolerance ≤0.01 mm.
2. Spring Compression: Compress per specifications (error ≤2 mm); excessive compression accelerates wear, insufficient causes leakage.
3. Dynamic Ring Flexibility: Ensure free axial movement; must rebound automatically when pressed.
4. Cleanliness: Keep sealing elements and cavity free of debris; lubricate with compatible fluid during assembly.
