Fine Abrasive Fluids in Positive Displacement Pumps

Doug Robinson30 Jul, 2021Business

An abrasive fluid is one that causes increased wear to the fluidic system by eroding surfaces through physical interaction. Erosion can occur from simple flow across a surface or by the abrasive particles interfering with internal component interactions within a pump. The types of particles can be large contaminants such as those experienced in wastewater applications, or they can be finely integrated pigments in the liquid which are intentional. These include paint pigments, ink pigments, suspended carbon, metal pigments and chocolate (when suspended in milk, syrup, etc.). This article will deal specifically with suspended abrasive particles less than 1mm in size.
