Product Description
Sliding Bearing SiC Sleeve for Canned Motor Pump
Silicon Carbide (SiC) Sleeve and Thrust Disc Assembly
The Sleeve and Thrust Disc Assembly is a critical component of sliding bearings, serving as both the support and rotational unit in canned motor pumps. Silicon carbide (SSiC) is renowned for its outstanding corrosion resistance, wear resistance, and superior material properties, making it an ideal sliding bearing material 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 Applications of Canned Motor Pump
1. The canned motor pump can be used in common corrosive conditions, such as with inorganic matter, acid, alkaline and salt media. In such conditions, SSiC (sintered) is the standard sliding bearing material.
2. The canned motor pump can be used in common corrosive conditions with media that is prone to vaporization.
