Thrust Washer with Pressureless Sintered Silicon Carbide for Canned Motor Pumps

The Sleeve and Thrust Disc Assembly is a part of sliding bearing. It serves as a critical transmission component, functioning as both the support and rotational unit in canned motor pumps. Silicon carbide (SSiC), renowned for its outstanding corrosion resistance, wear resistance, and superior material properties, stands as one of the most ideal sliding bearing materials for such pumps.

• Superior Wear Resistance: High hardness and low friction coefficient of SiC (SSiC/SiC) ensure extended service life.
• Corrosion Resistance: Immune to acids, alkalis, and high-temperature fluids, ideal for aggressive media.
• Thermal Stability: Low thermal expansion maintains dimensional accuracy under high-speed rotation.
• Customizable: Available in standard or integrated designs to fit various pump models.

• Chemical process pumps, nuclear coolant systems
• High-purity fluid transfer (e.g., semiconductor-grade chemicals)
• Sealless solutions for extreme pressure/temperature conditions

1. The canned motor pump can be used in common corrosive conditions, such as the medium of inorganic matter, acid, alkaline and salt. In such conditions, SSiC (sintered) is taken as standard sliding bearing.
2. The canned motor pump can be used in common corrosive conditions, and the medium easy to vaporize.

We have three factories in China, can meet the needs for different customers, and also we have advanced pressing, sintering and processing machines.
