Nigeria is No.1 petroleum country in Africa. With its relative stable politics surroundings and rich oil resources, more and more investor come to this country, making this country to be flourishing and productive.

GN Solids America will attend Nigeria Oil & Gas Show in 2015, taking the latest model Vacuum Degasser,During solids control & drilling waste management scope, Vacuum Degasser quality talks much. The company who can supply Vacuum Degasser similar to USA Vacuum Degasser working performance, but the price is reasonable; he will win the market much.

GN Solids America has exported over 30 sets Vacuum Degasser & Hi-G Dryer to Nigeria market. Among them, over 20 set are Vacuum Degasser,Some of the cuttings are transported to rigsite for solids control & waste management work, some of the Vacuum Degasser are used for waste water separation and purify. The feedback from one customer is very good. He wrote in his email : “ the performance of the 2 Vacuum Degasser is very good, One Degasser worked for about 3 days non-stop and there was no problem with the bearing. They are very good.

With this oil show, we believe GN Vacuum Degasser can get better market share in Nigeria.

NOV’s Mission Magnum is the most popular centrifugal pump in the drilling industry. Every year lots of wear pumps are required but because of the high cost and long delivery time, it is necessary to find a long term and reliable supplier for Mission Magnum centrifugal pump parts. GN solids control has the production capability to produce not only our own brand centrifugal pumps for 3×2, 4×3, 6×5, 8×6 series, but also we produce wear parts for Mission centrifugal pump Magnum and 250 series, because GN Decanter Centrifuge parts are replaceable with Mission’s.

Features of Magnum Centrifugal Pump:

The Magnum has an open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The Magnum pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration). 

Typical Applications of Magnum Centrifugal Pump:
• Barite, ferric oxide, and mineral oil
• Base drilling muds
• Glass fibers
• Sugar processing
• Ash or coal conveyers
• Cement
• Mine de-watering
GN own produced centrifugal pump models as below:

GNSB8×6A-14J, GNSB8×6A-12J, GNSB8×6A-13J,  GNSB8×6A-11J, GNSB6×5A-13J, GNSB6×5A-10J, GNSB6×5A-12J, GNSB6×5A- 9.5J, GNSB5×4A-13J, GNSB5×4A-11J, GNSB5×4A-12J, GNSB5×4A-10J, GNSB4×3A-13J, GNSB4×3A-12J, GNSB4×3A-12J, GNSB4×3A-10J, GNSB4×3A-11J

GNLW363 is always top seller decanter centrifuge of GN product list and that model is well known to many drilling companies and oilfield service companies. At beginning of year 2014, GN Solids Control has improved the design of this centrifuge by locating 2 motors on same side of centrifuge.

Technical advantages of GNLW363BG decanter centrifuge:

  1. GNLW363 centrifuge can get a high speed up to 3900 RPM, in case of VFD control, speed can be easily adjusted from 0 RPM to 3900RPM, can be suitable for various applications including middle speed and high speed.
  2. GNLW363BG uses International highest material, SS2205 for main body of rotating bowl and tungsten carbon tiles for impeller protection.
  3. Bearing for GNLW363BG is world famous high quality SKF bearings.
  4. GN’s special protection for bearings during transportation.
  5. GNLW363BG-VFD has 3 VFD control for main motor, back motor and centrifuge feeding pump.

Advantages for New Location of 2 Motors:

Comparing with formal design, 2 motors located separately on both sides of centrifuge, the functions and working principle for motors remain the same. But this design still has its advantages:

  1. More compact in structure.
  2. Easier to open the collection box cover, and leaving more space for maintenance.

Since early this year, GN Solids Control has started manufacturing for new design GNLW363 Centrifuges. Now there is one brand new, old model in stock for sale. It has same high standard of GNLW363BG high configuration centrifuge, only different location of motors. You can have a discount up to 20%.

Only 1 set left, may you have interest, pls do not hesitate, contact me now!


Recently, GN production department is busy with drilling waste management systems, because same orders come from different regions of world, one after another. The 3 OBM waste management systems are respectively for Asia, West Africa and Middle East.

This is a standard system with GNCD930C vertical cutting dryer, a hopper shape tank for receiving the liquid from the vertical cutting dryer, and a GNLW363BG-VFD for further treatment of drilling liquid. Solids parts discharged by this system is always buried or made into mud plate before burying.

When designing this system, besides the basic functions, GN engineer team take into consideration lots of factors, even including small details. As below:

  1. In GNCD930 vertical cutting dryer, air flushing system adopted for avoiding screen blocking cases.
  2. GNLW363BG decanter centrifuge is mounted on a telescopic skid, this skid can offer 3 optional heights for the centrifuge, easier for operator to lead the treated clean liquid back to a reserving tank.
  3. Liquid outlet of decanter centrifuge is designed with 2 branches, equipped with valve. One is to the side, in order to transfer liquid into reserving tank. The other is vertical, used for discharge liquid directly, and also helps flushing.
  4. GNLW363BG-VFD decanter centrifuge is international high standard decanter centrifuge, with positive pressurized VFD control and high standard material for longer service life and better performance.
  5. Tank between vertical cutting dryer and decanter centrifuge is shaped as a hopper, in this condition, solids particles remaining in liquid is adapt to settle down to the smaller bottom. On bottom there is a gate for discharge them on occasions and easy to flush.

Some customers who use WBM only can replace the vertical cutting dryer into a GNZS594HGE high G shale shaker and cost will be much lower.
