Roto-Jet®
RO-FT API 610
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.
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
