G Series

Environmental Decanter Centrifuges

Get dryer solids and clearer fluids with Allied's advanced bowl and scroll designs

  • Optimal length to diameter ratio for oilfield applications; this allows a longer beach section that removes and dries heavy solids with a reduced chance of plugging. The cylindrical section length has been specially designed to optimize clarification of the fluid. 

  • The solids discharge radius allows for a dryer cake while operating with a deep pond to remove low gravity and ultra-fine solids

Run your operations more efficiently

  • Enerports capture wasted energy from liquid exiting the bowl to aid in reducing the rotational energy required by up to 30%

  • Regenerative technology uses power from the back drive while operating in the same direction as the bowl to reduce the main drive power requirements. This results in a reduced load on the generator and increased machine processing capability

  • High efficiency, quality brand inverter duty motors

  • Revolutionary robust panel design with intuitive control interface

Allied seal technology

  • Pillow block seals only found on Allied decanters, is a proprietary seal design which uses centrifugal force on an intermediate ring to produce an ultra-close running, non-contact seal. This eliminates the concern of any contamination entering the bearing cavity, or loss of lubricant when loading on trucks, or operating on uneven surfaces.

  • The Allied G-force seals on the scroll, counteracts the expansion of the sealing shaft while being subject to G-force. This results in no contamination of the internal scroll bearings which in turn, extends the operating interval life of the decanter.

Planetary Gear Boxes

  • Allied’s specially engineered two-stage planetary gear units result in high torque carrying capacity, quiet operation and long-term reliability in severe weather environments.


Backed by the highest quality materials and parts

  • Bowl Sections: produced from solution annealed, stress relieved centrifugal castings

  • Bowl Heads: manufactured from solution annealed, stress relieved forgings

  • Scroll: manufactured from fully welded, centrifugally cast sections and stress relieved for reliability in service

  • Containment Case: manufactured from 1.4306 stainless steel and protected by removable wear liners in critical areas

  • All components quality checked to Allied ISO :9001quality conformance before service

Customize & accessorize your G Series Decanter Centrifuge

Allied Centrifuge Technologies G Series decanters can be customized to any customer requirements. Some of these options include:

  • Alex certified

  • Class 1 div1 certification and verification

  • Modular skid packages

  • Fixed speed configurations

  • Fully and partial hydraulic configuration

Gseries scroll design website.jpg
  • Our specially designed scroll features a variable pitch, double lead conveyor to optimize solids removal, capacity and efficiency. Customers have a choice between a full radial flow design or a higher capacity half axial flow design. The half axial flow design is better suited for water based drilling applications, while full radial flow design has a reduced capacity, which is better suited for oil-based drilling solids
