A05 Material Slurry Pump

The slurry pump is primarily used to pump solid-liquid mixtures containing hard particles. It is widely applied in industries such as coal, metallurgy, mining, thermal power, chemical engineering, water conservancy, transportation, urban sewage, and more. In the slurry pump, the transported solid-liquid mixture rotates irregularly at high speed, causing the overcurrent components to be continuously polished by what is referred to as a "liquid grinding wheel."

This process results in the transported slurry causing severe wear to the overcurrent components, which also endure corrosion from the medium. As a result, the service life of overcurrent components in slurry pumps is generally short. Frequent part replacements not only increase production costs but also significantly impact production efficiency.

From the perspective of operating conditions, the wear in slurry pumps is classified as hydraulic erosion and particle wear. Research has shown that the wear on most overcurrent components in slurry pumps manifests as micro-cutting, plowing, plastic deformation, and brittle fracture. Under moderate impact and low-stress wear conditions, a martensitic matrix is generally the most suitable material.

Guided by the composition, structure, and heat treatment processes of wear-resistant materials, the martensitic matrix demonstrates the following performance characteristics: strength = 700 MPa, hardness > 55 HRC, and impact toughness > 10 J/cm². A05 material fully meets these requirements and currently outperforms other matrix and composite alloy materials.

Our company is also capable of producing overcurrent component materials with a longer lifespan than A05. However, due to their relatively lower cost-effectiveness, A05 remains the most suitable choice for general customers without special requirements.

This explains why the slurry pump commonly uses A05 material.
