Silicon Carbide Sleeve and Thrust Disc Components for Canned Motor Pumps

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.

Our factory and processing machine:

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

Beijing Zhongxing Shiqiang Ceramic Bearing Co., Ltd., founded in 2005, situated in No. A38 Weishanzhuang Industry District, Daxing District ,Beijing, is the first company in China to invent and manufacture rare-earth ceramic bearings. The rare-earth ceramic bearings have characteristics of strong resistance against all kinds of acid, alkali, salt and other corrosive medium erosion, high temperature resistance, wear-resistant, dimensional stability at high temperature, etc. They can be used in worse lubrication working condition with a long operating life, thus it is a new kind of high-tech products material, with great social and economic value.

Besides, the founder of the company started theoretical research and process development on ceramic bearings as early as 1982, and obtained two national invention patents in 1992/1994 (Patent No. ZL92114993X for rare-earth ceramic bearings and Patent No. ZL94106294.S for ceramic ball processing technology).

At present, our company mainly produces ceramic bearings, sliding bearings, ceramic balls and ceramic industrial parts. The production materials are high performance ceramic materials, mainly SSIC, Si3N4, ZrO2, Al2O3.

The advantage of our company is that we have specialized production line for high precision ceramic balls, and we can produce customized GPS (Gas Pressure Sintering) and HIP (Hot Temperature Isostatic Pressing) sintered Si3N4 balls and ZrO2 balls. The quality of our products is equivalent to ASTM F2094 F2094M-08 standard class I and II materials, and the precision grade reaches international standard G3, G5, G10 ceramic bearing balls, etc. Please note that the most of equipment used in our production and testing process are from Mitsutoyo Japan, and the hot isostatic sintering furnace is from ABB Sweden, therefore, the quality of our products is absolutely superior. And we are confident that you will be satisfied with our products.

In 2017, Liaoning Zhongxing Shiqiang New Material Co.,Ltd., was founded, situated in 571 Jianshe Road, Jingkai District, Anshan City, Liaoning Province. The company mainly produces sliding bearings as well as pump accessories. And the pump accessories are mainly sold in domestic famous pump manufactures.

In 2020, Zhongxing Shiqiang Technology (Tianjin) Co., Ltd., was founded, situated in No.41 Guangyuan Road, Wuqing District, Tianjin. The company mainly produces rolling bearings as well as ceramic balls, and its productions are competitive in the international market.
