The Mechanical Seals are a pump most delicate parts. Although the seal rings are made from extremely hard materials such as Tungsten carbide or Silicon carbide, the seals should be handled with care. The extreme flatness tolerance of the Mechanical Seal faces allows for no distortion from physical shock or contamination by even the smallest of particles.
Mounting Water Pump Mechanical Seal:
The gap between the Mechanical Seal faces is on average less than 0.5 micrometers, which means that even small particles from a thumb print could separate the seal faces enough to create leakage. Normally, particles on the Mechanical Seal faces are worn away shortly after startup, but metal particles can cause leakage for a long time before they are worn away.
Extra care and attention while mounting Mechanical Seals will be repaid by greater operational reliability:
1. Keep seal faces clean;
2. Do not distort the seal rings by using excessive force;
3. Use the recommended service tools;
4. Follow the mounting instructions enclosed with the seal unit;
5. Examine the shaft, O-ring grooves and seal seat for scratches and damage;
