Customized Silicon Carbide Or Zirconia Sliding Bearing For Gear Pump
Description of Sliding Bearing for Gear Pump:
Sliding bearing is a crucial transmission part, as the support and rotary unit of gear pump. With the excellent corrosion resistance, wear resistance and other properties, silicon carbide (SSiC) is one of the best sliding bearing material for the pumps.
Main application of Gear Pump:
1. The gear pump can be used to transport the liquid with high viscosity and corrosion, and commonly used in high temperature.
2. The gear pump can bu used for metering.
3. The gear pump has the good advantages which other pump can't compare, especially for the transport of special material.
Why choose us:
According to the structure difference, it can be divided into: external gear pump and internal gear pump. Our company has ample production experience of both kind of the gear pump sliding bearing in material of silicon carbide. We did supply these SSiC sliding bearing for Germany Witte for many years.
