We are seeking agents to jointly expand the market. The "diamond" of the materials world—not all materials dare to challenge their limits.
Silicon carbide ceramic slurry pump
Under abrasive conditions in mining, ceramic pumps have a service life 4-8 times longer than metal pumps, and can handle a maximum particle size of 18 mm, meeting the pump requirements throughout the entire mineral processing process. High-quality ceramic slurry pump impellers and bushing replacements are available for AH series slurry pumps and are 100% interchangeable.
Extremely high wear resistance
Silicon carbide (SiC) impellers, sleeves, and wear plates are core components in wear-resistant equipment such as slurry pumps and chemical pumps. Their superior performance stems directly from the unique properties of silicon carbide ceramic materials. The following is a detailed analysis of its material hardness and overall performance:
Core Characteristic: Extreme Hardness
Silicon carbide is one of the hardest materials in nature, and its hardness is the fundamental guarantee of its wear resistance.
· Mohs Hardness: Approximately 9.2-9.5 (second only to diamond’s 10).
· Knoop Hardness/Vickers Hardness: Typically in the range of 2000-2800 kg/mm².
· Comparison: Hardness far exceeds that of commonly used wear-resistant metal materials.
· High-chromium cast iron: Approximately 600-800 HV.
· Alumina ceramic: Approximately 1500-1700 HV.
· Tungsten-cobalt cemented carbide: Approximately 1400-1800 HV.
This means that silicon carbide slurry pumps can effectively resist the cutting and chiseling wear of most abrasive particles (such as quartz sand and slag).
