Silicon carbide ceramic slurry pump: technological breakthrough leads a new chapter in the industry

HEBEI XINGOU MACHINERY EQUIPMENT CO.,LTD

There are various material options for slurry pumps, with metal and rubber being the main ones on the market at present. Metal slurry pumps include ordinary cast iron, wear-resistant steel, nickel hard cast iron, and chromium based white cast iron. When selecting materials for slurry pumps, different usage scenarios need to be considered. For example, when the solid particles in the medium are smooth and have no sharp corners, and the head of the slurry pump does not exceed 40 meters, rubber made overcurrent components would be a suitable choice. However, with the birth of silicon carbide ceramic slurry pumps, this situation is expected to be broken. Silicon carbide ceramic slurry pumps, with their excellent wear and corrosion resistance, can significantly extend their service life and reduce downtime in mineral processing plants. This technological breakthrough is expected to help domestic enterprises achieve overtaking in the pump field.

Silicon carbide ceramics occupy a place in structural ceramic materials due to their excellent physical properties. It has excellent high-temperature mechanical strength, high hardness, high elastic modulus, high wear resistance, and high thermal conductivity, while also possessing corrosion resistance. Its Mohs hardness ranges from 9.2 to 9.5, second only to diamond and boron carbide, and its melting point is as high as about 2730 degrees Celsius, demonstrating extremely high chemical inertness. As a result, silicon carbide materials have been widely used in various fields such as bearing bushings, ceramic nozzles, heat exchangers, sealing rings, and satellite reflectors.

The slurry pump made of silicon carbide ceramics exhibits excellent performance. Thanks to its excellent chemical stability, this slurry pump can resist almost all types of inorganic acids, organic acids, and alkalis. Meanwhile, its excellent wear resistance makes its wear resistance 3 to 10 times that of high chromium wear-resistant alloys. Therefore, choosing a silicon carbide ceramic slurry pump will significantly extend its service life, thereby reducing the downtime of the beneficiation plant.
We firmly believe that the excellent performance of silicon carbide ceramic slurry pumps will bring important opportunities for surpassing the domestic slurry pump industry.
