The wear is material destruction caused by cumulative damage between the solid particle impacts( friction or abrasive ) the wetted parts of the slurry pump.

Type of slurry pump wear is generally divided into chipping abrasion (caused by high-intensity impact, sometimes tear off debris), grinding abrasive (wear when the fine powder solids crushed between two surfaces,) and erosion wear (the high-speed or low-speed free movement abrasive, sometimes particles parallelly compact the grinding surface or collision the grinding).
