Rotodynamic pumps such as centrifugal pumps use a rotating impeller to increase the pressure of fluid through the piping system. AST Bearings has the knowledge and expertise to meet demanding specifications for the centrifugal pump industry. These fluid pumping systems often require a wide range of bearing types which AST Bearings is easily capable of supplying or engineering to meet specific liquid pump demands.

Centrifugal pumps are often critical to all types of manufacturing processes; bearing failures can mean catastrophic consequences, which can be both hazardous and expensive in downtime and/or damage to equipment. Bearing performance and reducing the risk of potential pump failures are critical factors that our ball bearing engineers can address up front. Common bearings for liquid pumping applications are our durable, high-precision angular contact bearings although other types of bearings are also used depending on the application and resulting design.
