RO-FT API 610

Roto-Jet®

RO-FT API 610

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. 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.

KEY FEATURES & BENEFITS

  • API 610 11th Edition compliant

  • Standard API 682 cartridge seals

  • No external lube system required

  • No wear rings or close running clearances

  • Low NPSH3 without the use of an inducer

  • Robust design is insensitive to process upsets

  • Pulsation free flow over the entire head-flow curve

  • Integral gearbox is isolated from process seal leakage

  • Reduced life cycle cost by optimizing hydraulic efficiency

  • Process seals exposed only to suction pressure to maximize seal life

  • Between bearings arrangement minimizes shaft deflection at the seals

  • Bearing L10 life exceeds API 610 requirements using rolling element bearings

  • Patented rotor eliminates radial and axial thrust as a function of flow rate and suction pressure

  • High heads achieved in a single stage at low operating speeds compared to other low-flow

  • High-head pumps
