When the solid-liquid mixture is pumped by slurry pump, the slurry pump impeller is the most worn part. Also other parts as slurry pump liner, throatbush, FPL inser will face wear problem too.
Bellow listed 5 main factors of wear problem
1) Rheological properties of solid-liquid-liquid phase.
2) Particle size, shape, hardness and density of solid particles.
3) The structure type and parameters of the pump.
4) Pump running speed or we can name it as impeller running speed.
5) The properties of pump materials, such as hardness, strength (elongation, acid and alkali resistance, heat resistance), etc.
Among the factors affecting the life of the slurry pump parts, material is the most important one.
The second is the characteristics of the medium
Third is the structure and hydraulic parameters of the pump
Last is the operating conditions
