GN Solids Control is China leading make for solids control products & drilling waste management products. We’ve been working in this field over 9 years, and the prosperous experience and professional get to be the power to enlarge GN effect in the domestic market in addition to overseas market. Up to now, GN already has GN Solids America facility, GN Solids Russia facility in operation. Regarding other areas, we have GN spouse or dealer to help market place the local market and share solids control equipment to get urgent projects.

GN Solids Control also attaches importance in Africa market. The Cameras oil field requirement can also be very large. As the huge industry and sensitivity of selling price, GN Solids Control effectively enters Africa market with good quality equipment and sensible price. One client instructed us” so far, the decanter centrifuge is working really fine with the heavy mud, but the other people at the rigsite are curious how long moment the good performance will last “. The decanter centrifuge is readily worked in Algeria over one years. So far so great.

We also have one consumer from Argentina who individual over 30 sets decanter centrifuge from us. The highly effective partner work for Baker Barnes and have his own mud company. The professional service along with good relationship help the customer occupy a large percentage of the local sector at mud service location. The clients also acquire some sets of top to bottom cuttings dryer to expand the service scope.
Within Australia, we have partner TT Asia who is dealer to get VERMEER, the famous drilling device brand. They buy mud system from us as well as match with Vermeer rigs. Solely in 2012, the client ordered about 10 sets mud mixing system from GN Solids control.

Why we can include so many clients and continuous buy from us? Because of the high quality equipment reasonable price as time after sales services.

In this article, we will mainly introduce the wide application of Shear Pump manufactured by GN Solids Control.


As we know, Shear Pump is specially used for shearing the high-molecular polymer and bentonite, which need to be fully sheared by the Shear pump before entering the drilling fluids system, then their functions could be fully played and improve the property of drilling fluids. If the high-molecular polymer and bentonite are not fully sheared, the polymer will block the screen in the first time circulation and massive polymer will be lost and increase the drilling cost.


As what showed in below picture, GNJQB series Shear Pump is specially designed for meeting to quickly configure and get high-performance drilling fluids. After been fully sheared by the Shear Pump, the high-molecular polymer could be more easily mixed and hydrated in the fluids and shorten the configuration time, thus improving the quality and efficiency of configuration drilling fluids.


GN Shear Pump

The Advantages of GN Shear Pump

1). Belt-driven and has a compact structure;

2). Special design with the impeller, a wider flow passage and smooth vanes design make the pump has a larger flow area and fluids could pass smoothly. Compared with similar products, the work efficiency is effectively improved and energy is saved more than 10%.

3). Thicker pump shell than normal one, with rational flow rate and occurring less turbulence;

4). The pump shell and impeller are made of high wear resistant cast irons with longer service life;

5). The shear pump has higher strength that can reduce shaft deflection and extend the service life of seals;

6). The Shaft is lubricated by lubricants or grease. The oil seal is made of special structure and material, which is suitable for high and low temperatures and complicated environment;

7). Front opening structure design, convenient for installation, repair and maintenance.

It is widely recognized that industry compliance standards are more demanding than ever,    with new regulations impacting every stage of the energy exploration chain-including waste management. GN Solids Control assists you ensure environmental compliance in order to obtain operational efficiency and economy.


1. Solids Control Equipment-Vertical Dryer


Typical after GN linear motion shaker processing, cuttings of liquid content is average ranging from 12% to 16%. New industry of regulations require the lower oil content of cuttings, GN vertical cutting dryer is able to achieve liquid content below 5%.  This can be done while managing between 30 tons ~50 tons per hour of drilling cuttings.


GN vertical cutting dryer is with easy operation and low maintenance. Cutting is fed by the auger, vacuum system or shear pump from shale shaker. The drilling cuttings are distributed to screen of cutting dryer with rotor speed. The cuttings are discharged to the environment, and fluid is pump to a GN decanter centrifuge for further treatment.


GN vertical cutting is with IECEX/ATEX explosion proof enclosure. It not only provides a safe environment but also supply an operator friendly machine


2. Solids Management Equipment- Two phase Centrifuge


After GN vertical cutting dryer process of drilling fluids, fluids still contains small solids. GN high speed centrifuge will further remove the solids from fluids. GNLW363 decanter centrifuge is capable of reaching 3200rpm for separating ultra fine particle/solids. GN provides both VCD and Fixed speed control. Fixed speed is operated with soft start or a VFD (variable frequency drive) controller is able to adjust the speed of main motor, back motor and feeding pump.  IECEX/ATEX explosion proof is also available.


GN’s rugged, continuous waste management system is widely applied for many drilling project domestic and international. We provide the most reliable solids control equipment for all over the world project. For more information you could contact with local distributor and sale representative.

Person who works on drilling site know that there are several additives in the drilling mud, like bentonite,clay and Polymer. When add the polymer into the drilling mud, we may use the shearing pump.


In a drilling mud recycling system, for the bentonite and other additives, we could use the centrifugal pump to shear and mixing them. But for long strings polymer, only the shearing pump could be used for its wider flow pass and smooth vanes.

Always the shearing pump is package together with hopper, mud gun and transfer line which could transfer the mixed mud into each tank compartment. The impeller of GN shearing pump is made of high wear resistant cast iron for longer service life. Any need for shearing pump and other solids control equipments, just feel contact with GN Solids Control.
