Drilling Mud Centrifugal Pump and Mud Agitator for Africa Client

Recently one batch of drilling mud centrifugal pump and mud agitators are ready to ship to Africa client.
The drilling mud centrifugal pump can be used as drilling mud transfer pump, mud pump charging pump, trip pump, desander desilter feeding pump, water pump, mixing pump, etc., we produced different model drilling mud centrifugal pump for different flow rate and lifting head.


The mud agitator consists of heavy duty gearbox and explosion proof motor, which is connected directly, it will be installed on top of mud tank for drilling mud agitating, to prevent the solids deposition in the drilling fluids circulation system, to ensure stable performance and uniform mixing of drilling fluids.
Features of GN G version mud agitator:
1. The helical bevel type heavy duty gearbox runs smoothly with less noise.
2. The motor is directly connected to the input shaft of the gearbox without belt transmission, the speed of the mixing impeller is constant.
3. Compact foorprint and reliable operation.
4. High mixing strength and wide agitating range, avoiding the phenomenon of current overload when the motor starts.
5. Including agitator shaft, double or single layer impeller, stabilizer
6. Except for direct connected G version mud agiator, GN also produce coupler type E version mud agitator, vertical type mud agitator.
The selection of motor power and impeller is usually determined based on the following points:


a. Mud tank type – cylinder or rectangle
b. Mud Tank size
c. Mud specific gravity
d. Rotation speed ratio
After collecting relevant information, we will select the mud agitator proper model and confirm motor power, shaft length, and impeller.

GN will show Second Generation 3 Phase Decanter Centrifuge at 2024 CIPPE Exhibition

GN solids control is going to participate in CIPPE 2024 exhibition next week, we will show the second generation three phase decanter centrifuge during the show. If you are interested in the 3 phase decanter centrifuge and want to know more information, welcome to visit GN stand at CIPPE 2024.
The exhibition information is as below:


Exhibition Name: The 24th China International Petroleum & Petrochemical Technology and Equipment Exhibition（CIPPE 2024）
Exhibition time: 25th-27th, March, 2024,
GN Booth No.: E2168
After moving to the new 80000m2 new facility, GN introduced new advanced machines and technologies, to develop more new equipments with new technology, the 3 phase decanter centrifuge is also updated according to our experience with clients. The 3 phase decanter centrifuge is widely used for oil sludge separation projects to separate oil, water, solids. The separation is flexible for different liquid phase proportion. The operator can use the adjustable impeller to adjust the pond depth of the heavy liquid conveniently during working. An adjustment mechanism causes the position of the impeller to change.


The bowl material is duplex stainless steel SS2205, the screw conveyor is made of duplex stainless steel SS2205, the screw propeller is protected by tungsten carbide tiles, the material distribution port and solids discharged port are protected by tungsten carbide insert, the bearing is made from SKF or NSK brand, the gearbox is planetary wheel type gearbox.
Except for the 3 phase decanter centrifuge, GN will also show ViST 4 panel shale shaker with electric driven vacuum unit, 14” decanter centrifuge with VFD system, GNLW554FT-VFD big bowl big volume decanter centrifuge for industrial waste treatment, 3 phase disc stack separator for oil sludge separation system, vertical cuttings dryer, vacuum pump GNSP-10B and GNSP-40B, screw conveyor GNSC14-12B, etc. For more details, pls contact with GN solids sales.

Drilling Cuttings Vertical Dryer System for Middle East Client

Recently one set of drilling cuttings vertical dryer system are ready for delivery to Middle East Client, the client just finished inspection before delivery to inspect the fitting and performance of the vertical cuttings dryer system.


The vertical cuttings dryer system consists of the equipments as below:
1. Vertical cuttings dryer GNCD930G
2. VFD decanter centrifuge GNLW363D-VFD
3. Screw conveyor 2 sets, one as flushing pump of vertical cuttings dryer, one as feeding pump of decanter centrifuge, their control is inside the control panel of vertical cuttings dryer and decanter centrifuge. The decanter centrifuge VFD control panel
4. Screw conveyor, to transfer the drilling cuttings to vertical dryer system continuously. GN produced screw conveyor have been widely used to transfer drilling cuttings, waste sludge with high solids content but less moisture, industrial waste, etc. materials in the world. GN screw conveyor with each section standard length of 12ft, we can make it with different numbers of sections for different transfer length, as 12 ft with 1 section, 24 ft with 2 sections, 36ft with 3 sections, 48ft with 4 sections. There are sealing rubber between sections and fastened with bolts. The connecting shaft between the middle section and the adjacent blade shaft should be securely fastened with bolts, and the blades at both ends of the hinge bearing should have continuity. When the screw conveyor is installed slantly, GN produced telescopic bracket can be used for angle adjustment. The closed plate cover or grating cover can be selected as requirement.

If you need a customized solution for drilling cuttings treatment system, pls contact with GN solids sales engineer.

Vacuum Degasser and Mud Agitator for China Oilfield Service Company

Several sets of vacuum degasser and mud agitators are ready for delivery to China oil oilfield service company.


GN solids control can provide different types mud agitator for different application, including coupler connection mud agitator, direct connection mud agitator, vertical mud agitator, etc. The gearbox to be used with mud agitator is heavy duty helical bevel type gearbox for reliable operation, especially suitable for heavy mud. We will install different explosion proof standard motor for different project’s requirement, control panel can be optional as client’s requirement, such as IEC EX, ATEX, CNEX, etc. The impeller size and shaft length can be customized as your mud tank dimension.
When the agitator impeller come into contact with the drilling fluids, it forces it to generate vortex motion, thereby preventing the sedimentation of solid particles in the drilling mud, achieving the effect of uniform mixing of solid and liquid phases and consistent density. The connecting plate sandwiched in the middle of the impeller can prevent the solid particles of mud from depositing in the lower part of the impeller after shutdown, thereby reducing the resistance of solid materials to the impeller when starting again, and avoiding the accident of burning the motor due to starting overload. When motor is running, it drives the input shaft of the gearbox to rotate through the rotation of the motor. The output shaft of the gearbox drives the mixing shaft to rotate through a rigid coupling, and the mixing shaft is connected to the impeller through bolts for transmission.
To select proper quantity and model mud agitator for the solids control system mud tank, we will clear the drilling fluids density, mud tank dimension, equipments list, etc. information, then we will select proper model for our client.
