The Roto-Jet® RO-FT API 610 pump was designed specifically for demanding low-flow, high-head services, and fully meets the requirements of API 610. The RO-FT between-bearing configuration provides a reliable, robust, and easy to maintain pump for the midstream and downstream refining, petrochemical, and chemical processing industries.
The operating characteristics of the Roto-Jet® RO-FT API 610 pump are similar to a conventional centrifugal pump. Energy is added to the fluid via the rotor, and the stationary Pitot tube converts the fluid velocity energy into static pressure.
In addition, the Roto-Jet® RO-FT API 610 pump is specifically designed to achieve a broad operating range. These attributes result in improved mechanical seal and bearing life to maximize Mean Time Between Failure, and decrease operational and maintenance costs, which make the Roto-Jet® the most cost effective choice for low-flow, high head process applications.
