The Sulzer OHHL Pumps are an extremely popular API 610 pump found in chemical plants and the oil and gas industry across the world. Most commonly found in light hydrocarbon boosting, Light and Heavy vacuum gas oil (LVGO & HVGO), these pumps have proven to be robust and reliable in chemical plants, pipelines, and refineries.
Usually the OHHL 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 stationed in wet and humid areas, the bearing housings have issues with water vapor ingress. Isomag bearing isolators are a positive seal and will hold oil in, and keep the external contaminates out of the bearing housing. Many customers from Shell, Phillips 66, Enbridge Pipeline, and Valero refining have found Isomag bearing isolators to be their best solution for maintaining their maintenance lifetime goals.
