Overview
Pumps and Valves are a significant part in transfer of media such as chemicals, fluids, resins, gases etc. specifically in the Oil & Gas and Chemical industries where the nature of media is extremely abrasive and corrosive. Pump components are subject to abrasion, erosion, cavitation and sliding wear during process. Abrasion and erosion results from abrasive particles in the medium being pumped, but even in the absence of any abrasive particles, sliding wear can occur due to unintentional contact between rotating and stationery components. Moreover these wear rates in pumps are often unexpectedly high because of the synergistic relationship between wear and corrosion. As the pump components in the flow path wear, clearance between sealing surfaces increase and vane angles change, resulting in increased vibration or leakage and decrease in pump efficiency over time. A range of Thermal spray coatings for different components in the pump and valve assembly exhibit improved wear and corrosion resistance thereby increasing the operational life and reducing downtime costs.
