Omnirise – FSubsea

Omnirise™ Subsea Pumping Systems

Seal-less “Fit & Forget” pumping systems for permanent subsea use.
Zero discharge of toxic barrier-fluid and minimal maintenance required.
Handles virtually any liquid.

Omnirise HydroMag™

Hermetically sealed with magnetic coupling and built-in variable speed

Omnirise Mag™

Hermetically sealed with magnetic coupling

Omnirise HiDi™

Hermetically sealed with High Pressure Diaphragms

Omnirise HydroMag™

Hermetically sealed with Magnetic Coupling and Torque Converter

This all-electric pump system is seal-less with the drive unit hermetically separated from the process fluids. It has built-in hydrodynamic variable speed functionality with robust and real-time adjustment to process requirements. These features are enabled by a patented, high performance magnetic coupling embedded with a fluid torque converter, developed in partnership with Voith Turbo. A single powercable can supply multiple pumps, making it the most flexible and versatile system of its kind.

Omnirise Mag™

Hermetically sealed with magnetic coupling

This is the world`s first subsea process pump that does not require any mechanical seal or barrier fluid system. Furthermore, versions with lower than 50kW power are easily integrated with a unique electric Subsea Variable Speed Drive (VSD). The core and proprietary technology of the centrifugal boosting system received the OTC Spotlight Award in 2017 and is currently available in the marketplace for a variety of subsea boosting and circulation applications.
