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 HiDi™​

Hermetically sealed with High Pressure Diaphragms

Omnirise HydroMag™

Hermetically sealed with Magnetic Coupling and Torque Converter

This “all-electric”  pumping system is seal-less and 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.

Technical specification

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 clectric 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. 

Technical specification

Omnirise™ HiDi​

Hermetically sealed with High pressure Diaphragms

This seal-less volumetric subsea pumping system has been run in ambient pressures up to 300 bar (3000m). It is highly efficient under a large range of operating points and versions up to 50kW can be supplied with a qualified subsea electric Variable Speed Drive. The system is reliable and suitable for a multitude of tasks including desalination, chemical injection, well intervention and P&A applications. Versions up to 250 lpm (15 m3/hr) readily available.
