The Centric Reciprocation is a unique and patented rotary displacement technology

Page last modified
April 11 2024

Inner and outer rotor has two vanes each, rotating in the same direction with variable angular velocity 90 out of phase.

Each chamber expands and contracts twice per revolution -> Enables high capacity per unit.

Each revolution vields 8 full compressor/pump strokes.

Suction/exhaust are formed in four voids between vanes (arranged in front and back of barrel or on sides).

The technology is ready for market and well suitable for applications such as: booster pump, mud pump, CO2 pump, heat pump. wet gas compressor.

 

Pros & Limitations
1
Water sealing fluid provides efficient cooling for nearly isothermal compression process
1
Low internal friction due to non contact compression chamber sealing
1
High output – Low energy consumption (kWh/m3)
1
Oil separation and cooling systems are not required
1
The high tolerance for liquid and contaminations allows for process steps like e.g. scrubbing and drying to be done after compression at a lower volume
1
Positive displacement, self priming, positive suction head
1
Robust and reliable, particle resistant, suitable for multi-phase pumping and wet gas compression
1
Modular, simple, repair friendly design
