Product Description


Silicon Carbide (SiC) Sleeve and Thrust Disc Assembly


Description of Sliding Bearing for Canned Motor Pump:


The Sleeve and Thrust Disc Assmbly 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.  


Key Features:

  • 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.


Typical Uses:

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

Main application of Canned Motor Pump:


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

2. The canned motor pump can be used in common corrosive condition, and the medium easy to vaporized.
