In recent years, decanter centrifuges with brand GN Solids Control is more and more popular and accepted by end users all over the world. From the extremely low temperature in countries like Russia, to the extremely high temperature countries like Kuwait, you can easily find GN centrifuges working on the jobsite. GNLW series decanter centrifuge models cover nearly all necessary applications in the oil and gas industry, and in some slurry treating industries and also for mining.

Now for oil and gas solids control and drilling waste management industry, we all use Horizontal sedimentation centrifuge, and we call all of them decanter centrifuges or centrifuges for short.

GN has a full series of horizontal sedimentation centrifuges, ranging from 9 inch diameter bowl to 22 inch diameter bowl, and all those centrifuges could be divided into two catalogs, the economic configuration, GN standard models, and the highest configuration, the internationally highest standard and materials.

Take GNLW363 Decanter centrifuge for example, which is also the most popular model, there are totally 5 options, see the detailed compassion as below:

Grouped in configurations and material used for centrifuges:

  1. high configuration, GNLW363CG/GNLW363CG-VFD, we use best material and parts, like SS2205 by centrifugal casting for bowl material, SKF bearings. and tungsten carbide tiles for impeller protection. We compete with other top manufacturers from USA and Europe.

Main applications : waste management centrifuge, dewatering centrifuge, and slurry industries for extra fine particles.

  1. economic configuration: GNLW363CD/CD-VFD, ss304 by centrifugal casting for bowl material, NSK bearing and ceramic tiles for protecting impeller.

This model is mostly used inside China, comparing with other China suppliers, this model has better quality, but price nearly same.

Main applications: solids control centrifuges mostly for barite recovery and fine particles, as the forth step of solids control system.

For the optional electric control panels, GN totally has 3 options, Positive pressurized control panel, flame proof VFD control panel, and flame proof fixed speed control panel. For the economic configuration GNLW363CD, all three options for electric control panel available, while for the high configuration, there are positive pressurized control panel available.
