Isomag Bearing Isolators : The Best Solution For KSB WKT API Pumps

KSB WKT Pumps are an extremely popular API 610 pump found in chemical plants and the oil and gas industry across the world. The WKT process pump for the chemical and petrochemical industries is a vertical, radially split, multi-stage ring section pump with radial/mixed flow single entry impellers, these pumps have proven to be robust and reliable in chemical plants, pipelines, and refineries.


Usually the WKT line is equipped with a labyrinth from the OEM. Which has commonly been found to have an oil leakage issue. Many customers have tried other style labyrinths which typically fair better on the leaks. However since most of these pumps are in oil bath or oil mist lubrication environments, positive sealing is needed for extended maintenance cycles. Isomag bearing isolators are a positive seal and will hold oil in, and keep the external contaminates out of the bearing housing. HPCL in India has two refineries that have found Isomag bearing isolators to be their best solution for maintaining their maintenance lifetime goals.
