High chromium alloy material
Wear resistance: It has excellent wear resistance and can resist the wear of high concentration and high hardness solid particles. For example, when transporting high hardness media such as ore slurry and grinding slurry, it can withstand long-term friction with minimal loss.
Corrosion resistance: It has good corrosion resistance and can also tolerate slag slurry media with certain corrosiveness.
Applicable working conditions: Suitable for conveying high concentration, high hardness, and high corrosiveness slurry media, such as ore slurry, grinding slurry, tailings slurry, etc.
Specific classification:
High chromium cast iron: usually containing 12-30% chromium and 1.5-3% carbon, with high hardness, can effectively resist wear and corrosion, and is suitable for handling corrosive media containing solid particles.
High chromium steel: generally containing 12-27% chromium, it has good wear resistance and corrosion resistance, and is suitable for processing high concentrations of solid particles.
High chromium alloy steel: usually containing 15-30% chromium, it also has excellent wear resistance and corrosion resistance, suitable for handling high concentration and high hardness solid particles.
Rubber material
Wear resistance: It has good wear resistance and can reduce wear caused by particle friction during transportation.
Corrosion resistance: It has good corrosion resistance and is suitable for transporting slag slurry containing corrosive media, such as acidic and alkaline solutions. It is also suitable for transporting waste materials and media with strong acidity and alkalinity.
Other features: It can effectively reduce the noise and vibration of the pump because its material itself has good elasticity.
Applicable working conditions: Suitable for conveying low concentration, low hardness, and weakly corrosive slurry media, such as coal slurry, mortar, etc., as well as gelatinous substances containing particles, such as mineral water, fruit pulp, etc.
Stainless steel material
Corrosion resistance: With good corrosion resistance, impellers are usually used for conveying chemical media and industries with high hygiene requirements, such as the food industry, pharmaceutical industry, etc.
Wear resistance: It has a certain degree of wear resistance and abrasion resistance, but may not perform as well as high chromium alloy materials when transporting high hardness particles.
Other characteristics: The material is relatively hard, the density is high, and the cost is relatively high.
Applicable working conditions: Suitable for conveying slurry media with general concentration, hardness, and corrosiveness, such as sewage, chemical wastewater, etc.
Cast iron material
Wear resistance: It has good wear resistance and can withstand a certain degree of particle wear.
Corrosion resistance: It has a certain degree of corrosion resistance and can be used to cope with general corrosive environments.
Applicable working conditions: Suitable for conveying slurry media with general concentration, hardness, and corrosiveness, such as coal gangue, gravel, etc.
polymer composites
Wear resistance: It has excellent wear resistance and can maintain good wear resistance when facing high concentration and high hardness solid particle impacts.
Corrosion resistance: It has good corrosion resistance and can adapt to highly corrosive slurry environments.
Impact resistance: It has impact resistance and can withstand the impact of particles during transportation without being easily damaged.
Applicable working conditions: Suitable for conveying high concentration, high hardness, and high corrosiveness slurry media, such as grinding slurry, tailings slurry, etc.
Polyurethane material
Wear resistance: It has high wear resistance and can effectively resist the wear of solid particles.
Corrosion resistance: It has a certain degree of corrosion resistance.
Applicable working conditions: Suitable for conveying high concentration and high hardness slurry, with a long service life.
Ceramic material
Wear resistance: It has extremely high hardness and wear resistance, and can effectively resist the wear and corrosion of solid particles in high concentration and high hardness slurry transportation.
Applicable working conditions: Suitable for conveying high concentration and high hardness slurry, with an extremely long service life, but may have certain limitations in use due to material brittleness and other issues.
Cast steel material
Wear resistance: High strength and hardness, good wear resistance, able to adapt to the transportation of high hardness, high concentration, and high viscosity slurry.
Other characteristics: The disadvantage is that the material is relatively brittle and prone to fracture, which needs to be considered in its impact on the lifespan of the impeller during use.
Applicable working conditions: Suitable for conveying high hardness, high concentration, and high viscosity slurry.
When selecting the material for the impeller of a slurry pump, it is necessary to comprehensively consider factors such as slurry concentration, particle hardness, and corrosiveness based on specific operating conditions, and make appropriate decisions in combination with economy and maintainability to ensure the normal operation and long-term stable performance of the slurry pump.
