Slurry pumps are essential for mining industries, where they are used to transport solid or abrasive materials. These pumps must be designed with abrasion resistance in mind in order to reduce wear and tear and lengthen the lifespan of machinery. Several factors should be considered when designing a slurry pump for abrasion resistance.

Type of Slurry

The type of slurry being transported is a major factor in designing a pump with abrasion resistance. Slurries with high concentration of solid particles, such as sand and gravel, tend to be more abrasive. Therefore, slurry pump designs for these types of slurries will often have thicker pump walls and impellers made of more durable materials such as ceramic or highly alloyed chrome steel.

Pump Materials

The materials used to make a slurry pump also affect its abrasion resistance. Materials chosen for the pump must be able to withstand abrasion and corrosion. Some of the most commonly used materials for abrasion-resistant slurry pumps include high chrome iron, ceramic, and rubber. High chrome iron is used for its excellent wear resistance, while ceramic is suitable for its hardness and resistance to abrasive materials. On the other hand, rubber materials are best suited for less abrasive slurries.

Pump Liner Design

The design of the pump liner also affects abrasion resistance. The pump liner protects the internal surfaces of the pump from abrasion damage. The liner should be smooth and free of any roughness that can contribute to internal pump wear. Additionally, it should be made of materials that are both strong and resistant to abrasion. Thick liners are ideal for slurry pumps designed for more abrasive slurries, while patterns can be molded into liners to improve abrasion resistance.

Pump Impeller Design

Another component of the slurry pump that affects abrasion resistance is the impeller design. The impeller is responsible for moving the slurry through the pump. It should be designed to reduce turbulence, which can cause wear and tear on the pump. The impeller may be made of materials such as ceramic or high chrome iron to reduce abrasion while maintaining the necessary strength. It is also important to note that proper alignment of the impeller can reduce unnecessary wear and tear on the pump.


Maintenance of slurry pumps is essential in preserving its abrasion resistance. Poor maintenance can lead to increased wear and tear on the machinery, ultimately shortening its lifespan. Maintaining the pump liner, the impeller, and the pump casing is crucial in ensuring the pump continues to function well. One way to extend the life of the slurry pump and decrease the frequency of maintenance is to install a lined pipe system. These systems reduce the risk of blockages and abrasion while increasing the efficiency of the pump.


When it comes to selecting a slurry pump for abrasion resistance, in-depth consideration and careful selection are necessary. The type of slurry, materials, pump liner design, impeller design, and maintenance all play important roles in prolonging the life and usefulness of the machinery. Proper design and maintenance of slurry pumps not only reduce the costs associated with repairs and replacements but also ensures the safety of workers and the efficient operation of mining industries.
