When improving the performance of mission-critical pumps, John Crane’s customers face challenges, including high heat generation, poor lubrication, abrasion and barrier system complexities.
To solve these problems, we developed a face treatment, called **Dynamic Lift Up-stream Pumping**, as part of our suite of seal face technology options for rotating equipment.
Drawing upon our pioneering gas seal innovations in the 1960s and 1970s, John Crane engineered the Dynamic Lift Up-stream Pumping concept for liquid services and launched this face treatment three decades ago.
Today, we answer operators’ toughest challenges, improving seal and pump reliability, preventing unplanned downtime and reducing operating costs across a broad range of process industries.
