Centrifugal Pump Mechanical Seal Tungsten Carbide Rings
Mechanical seal ring are used to seal the clearance between the rotating shaft and the stationary housing in equipment .
Tungsten carbide is the most excellent seal face material in the seal material world.
One of main reasons for using Tungsten Carbide is the additional wear resistance that can be achieved in both moving and static parts.
This is particular the case in serve service conditions, such as high temperature,and high levels of corrosion and abrasion.

Our Quality control
During production process, we adopt the advanced production system and modern technology to monitor all-round quality control form the raw material to final product.
1. Chemical component analysis of the raw material.
2. Chemical analysis of the RTP powder.
3. Physical property testing and metallographic analysis based on trial production.
4. Testing the tolerance and deformation of the trial products.
5. Testing the physical properties of every batch of the sintered products.
6. Flaw detection of the molds and end products.
7. Testing the sizes, precision and defects of the end products.
