Sleeves And Plungers Input: 3.3

Sleeves and Plungers A major expense associated with pump operation is replacement of sleeves/plungers. Wear on these components necessitates:Frequent packing adjustment to compensate for dimensional changes caused by wear.Packing material failure due to sleeve surface roughness.Premature pump stoppage due to leaks.  The main causes of the problem are: Abrasion, Corrosion and friction.  The Solution is to provide a long lasting wear resistant surface of ceramic oxides or metallic carbides. We have a robotic Plasma transferred arc system (PTA) and flame spray equipment to apply coatings of tungsten carbide in a nickel chrome boron matrix and chromium oxides. The coating thickness is selected based on application wear potential and varies from 0.5mm to 1.5mm in thickness. For severe wear applications PTA coated sleeves last longer. Our Major Consumers are: Thermal power plants, Sugar industries, Oil and gas sector and chemical process plants.
