API 610 Roto-Jet Pump Product Feature

The Roto-Jet® RO-FT API 610 pump provides a reliable, robust pump for the midstream and downstream refining, petrochemical and chemical processing industries.  Designed specifically for demanding low-flow high-head services, this pump fully meets the requirements of API 610.

Roto-Jet-RO-FT-API-610The operating characteristics of the Roto-Jet RO-FT API 610 pump are simple and 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 has been specifically designed to achieve a broad operating range without generating damaging hydraulic forces during a process upset. These attributes result in improved mechanical seal and bearing life to maximize Mean Time Between Failure, and decrease operational and maintenance costs. This makes the Roto-Jet the most cost effective choice for low-flow high head process applications.

API 610 RO-FT Pump Features

  • API 610 11th Edition compliant
  • Standard API 682 cartridge seals
  • No external lube system required
  • No wear rings or close running clearances
  • Low NPSHr 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 for maximum 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
