FSD Series ANSI Process

FSD Series ANSI Process

The FSD Process ANSI pumps are used in a variety of industrial applications such as steel mill, mining, power generation and oil & gas applications. This heavy wall, reverse-vane, 304 investment cast stainless steel impeller design provides a durable and dependable product and is perfectly suited for petrochemical applications. These heavy duty process pumps feature double row outboard and single row inboard bearings standard. Each bearing housing is oil-lubricated to ensure maximum bearing life. Grease lubrication and oil mist bearing lubrication is also optional.
