GN Decanter Centrifuge and Centrifugal Pump For Russia
As one of the largest market for GN Solids Control, Russia market is playing a more and more important position in increasing GN Solids Control sales revenue. GN Solids Control works closely with many large customers in Russia in the oil and gas drilling mud treating.
In 2014, GN Solids Control provided some sets of drilling waste management treating systems include GN Vertical Cuttings Dryers and GN Decanter Centrifuges. And GN Solids Control has a partner in Russia name Akros. Every year, they purchased a lot of GN Solids Control equipment.
Besides those above mentioned customers, GN Solids Control also has many other partners keeping using GN equipment. GN made shale shaker, decanter centrifuge, cuttings dryer as well as turnkey treating equipment are widely used by hundreds of customers in Russia. Word of mouth successful projects are helping GN to grow faster and larger.
So last month GN Solids Control provided some solids control equipment to a Russian customer, it includes GN decanter centrifuges and centrifugal pumps.
1.GN Decanter Centrifuge
GN Solids Control manufactures different sizes of decanter centrifuges, GN14 inch bowl centrifuges, 18 inch bowl centrifuges and GN 22 inch bowl centrifuges are largely used in drilling mud solids control and waste management. GN Solids Control also built 9 inch bowl centrifuge for small flow rate treating, like diamond drilling, mining, lab scale waste water treating. Also GN Solids Control manufactures 30 inch bowl decanter centrifuges that arr very popular in tunneling, mining slurry treating as well as environmental waste slurry treating. 
2.GN Centrifugal Pump
GN made centrifugal pumps are totally interchangeable with NOV Mission magnum pumps. GN Solids Control provided different sizes centrifugal pumps from 3x2 to 8x6. Also, GN Solids America which is the branch company of GN Solids Control based in Houston, USA keeps many centrifugal pumps in stock.
GN 9 inch Centrifuge in Houston, TX
GN Solids Control manufactures different rotating bowl sizes of centrifuge, which cover the 9 inch bowl, 14inch bowl, 18 inch bowl, 22 inch bowl and 30 inch bowl. Different centrifuges are using in different area. Today we would like to give a detail introduction about GN 9 inch bowl centrifuge which we also called baby centrifuge or mini centrifuge.
GN 9 inch centrifuges are largely using in diamond drilling, core drilling, label scale slurry treating as the flow rate is around 30 gpm. Every other years, GN Solids Control upgrade its equipment in order to have a much better working performance. Now the 9 inch centrifuge GN Solids Control manufacture is the D version which comes from the original A version gradually.
GN 9 inch centrifuge bowl is also made of duplex stainless steel by centrifugal casting like the other GN bigger bowl centrifuges. There are mainly 2 models: one is fixed with single driven motor and the other model is driven by 2 separated motors.
GN 9 inch centrifuge also provides fix speed control and variable speed control to choose. Usually, if you only treat one slurry, use the fix speed is more cost effective, anyway it can also change speed by using different pulleys and belts. While the VFD is more convenient to adjust the rotating speed on the control box.
GN Solids Control is also open to provide only the centrifuge rotating assembly without motor and centrifuge foundation. Customer can choose to make it their own brand by assembling motors and paint in different colour with their own logo.
Every year, GN Solids Control manufactures and sells about 300 sets decanter centrifuges, among them 50 sets are GN 9 inch bowl centrifuges.
GN 9 inch bowl centrifuges are very popular in North America and South America, many local diamond drilling companies or mining slurry treating companies are using GN made centrifuge. 
Sometimes, if there are too many large particles in the slurry, a shale shaker will be highly recommended to add in front of the centrifuge.
GN Offshore Drilling Mud Treating System for COSL Offshore Rig
GN Solids Control equipment has provided thousands of solids control systems that used for onshore and offshore drilling rigs. As we all know, GN Solids Control has manufactured and provided solids control equipment to more than seventy countries and regions.
It’s relative easier to provide solids control systems for onshore drilling rigs, while it’s a little more complicated when using for offshore drilling rigs. Today we would like to share one solids control system that we provided to a COSL offshore rig.
It mainly includes these treating equipment: shale shaker, mud cleaner, decanter centrifuge, mud tank, centrifugal pump and screw conveyor.
1.Shale Shaker
GN shale shaker is one of the most cost-effective shakers in the world. GN shaker deck is all stainless steel. GN patented C-type groove is using 2.8 mm thickness SS, which is inserted with rubber to have a long time protection of shake screens. Also GN Solids Control made varieties of shaker screens includes GN own screens and the other popular sizes.
2.Mud Cleaner
GN mud cleaner is a 3-in-1 treating unit: GN shaker, GN desander and GN desilter. It is a 2 phase treating unit as desander separate solids larger than 55 microns and desilter eliminate solids larger than 25 microns.
3.Decanter Centrifuge
GN decanter centrifuge plays a very important role in drilling mud separating. GN Solids Control provides different sizes bowl centrifuges which are widely using in barite recovery, solids control , thickening and dewatering. GN Solids Control provides VFD control box that suits for IEC Ex, ATEX explosion-proof environment. DNV lifting certificate is also provided for the offshore usage. 
4.Mud Tank
GN mud tank is the storage tank to keep the drilling mud and also the foundation of all the above treating equipment as they will all fixed on the top of the tank. Centrifugal Pumps and Screw Conveyors are also provided in this system as auxiliary treating equipment.
