10 Sets Fully Hydraulic Drive Centrifuge for Drilling Mud to North Africa

Recently 10 sets of fully hydraulic drive decanter centrifuge for drilling mud cleaning are ready for delivery to North Africa.
The technical configuration is as below:


Model : GNLW363D-FHD
Bowl diameter: 14 inch (360mm)
Bowl length: 50 inch (1271mm)
The max speed is up to 3600rpm, the max G force is up to 2610G
The drive system is fully hydraulic drive system with adjustable speed, we use the reliable brand FHD system for reliable operation.


The Fully hydraulic drive decanter centrifuge can be utilized for oil and gas drilling solids control system, drilling waste management project, oil sludge treatment project, HDD mud recycling, , HDD tailing slurry dewatering, TBM slurry separation, construction engineering mud treatment, mining slurry separation, etc. Compared with VFD ( variable frequency drive) decanter centrifuge, the FHD centrifuge can be applied for heavy duty, simple operation, more flexible to meet the different working conditions.
Features of GN FHD decanter centrifuge:

  1. The centrifuge bowl assembly use high level stainless steel material, duplex stainless steel SS2205 or SS2304 by centrifugal casting, which is superior to the performance of SS304 and SS316.
  2. Multi speed balancing of different rotation parts to ensure the stable operation of the centrifuge under the high speed working condition.
  3. Screw blade is protected by tungsten carbide tiles, which is adjustable once damaged. Compared with hard facing wear resistant coating, it can last longer and the further maintenance cost is cheaper for the long run operation.
  4. The solids outlet and mud distribution port is protected by replaceable hard alloy sleeve.
  5. The carbide scrapers to protect the bowl and prevent it from wear. The 360 degree rectangular slag discharge port for smooth discharge and avoid blocking the bowl inside.

VFD decanter centrifuge and Full Hydraulic Drive decanter centrifuge

As a manufacturer of decanter centrifuge in China, GN solids control can produce different types decanter centrifuge for many different applications, including oil and gas industry used VFD decanter centrifuge and full hydraulic drive decanter centrifuge, rated speed decanter centrifuge, which can be used for drilling fluids solids control centrifuge, drilling waste treatment centrifuge, oil sludge treatment centrifuge, mud dewatering centrifuge; and industrial waste water treatment decanter centrifuge. Especially for VFD decanter centrifuge and full hydraulic drive decanter centrifuge, they are the most popular decanter centrifuges.


The centrifuge bowl assy is same for the VFD decanter centrifuge and full hydraulic drive decanter centrifuge, the difference between them are motor power and drive system.
Simply speaking, VFD decanter centrifuge is drived by VFD control panel, mostly the VFD control panel is positive pressurized, we can provide CNEX, ATEX, IEC EX based on different client’s requirement, and the suitable ambient temperature from -20℃ to + 40℃ or +55 ℃. Take GNLW363C-VFD decanter centrifuge as example, the main motor power is 50HP, the back drive motor power is 15HP, the feeding pump motor is normally 10HP, sometimes use submersible slurry pump, it is 7.5HP. The VFD decanter centrifuge will be lay on the telescopic skid directly or on top of mud tank with support leg.


Full Hydraulic Drive decanter centrifuge is drived by VISCOTHERM Full hydraulic drive system, The advantage of the FHD centrifuge is for use in high temperature ambient for heavy mud with flexible bowl
and differential speed. The compact one skid design makes it easier for rig up. Take GNLW363-FHD decanter centrifuge for example, the main motor power is 45KW, the electric control with PLC smart control, The torque gearbox is up to 4163 N.M (3260 ft.lbs)for heavy mud separation.

Full Hydraulic Drive Decanter Centrifuge manufacturer in China

As the professional manufacturer of full hydraulic drive decanter centrifuge in China, GN solids control developed full hydraulic drive decanter centrifuge with good quality good performance lower maintenance cost, and shipped it to clients in Middle East. We can design and produce rated speed decanter centrifuge ( high speed and middle speed), VFD decanter centrifuge and full hydraulic drive decanter centrifuge for different applications. We have different bowl size, bowl length for various client’s requirement, including 9 inch, 14 inch, 18 inch, 22 inch, 30 inch, the bigger ratio of the bowl length/ bowl size, the better result of the treatment slurry/ waste water.
The features of Full Hydraulic Drive Decanter Centrifuge:
1) Driving system is VISCOTHERM full hydraulic drive system for reliable performance and after sales service


2) The explosion proof standard is ATEX for zone 1 application
3) The differential speed is adjustable from 10 ~ 60 rpm, the bowl speed is adjustable from 0 ~3600rpm, the adjustable bowl speed, differential speed and pond depth to archive different dryness requirement according to different material conditions.
4) The max torque is 4163 N.M (3260 ft.lbs) for heavy mud treatment
5) The max treating capacity is 200gpm for water
6) The max G force is 2610G under 3600rpm
7) The SKF bearing for longer durable life, and adopt high environmental temperature
8) PLC smart control for easy and convenient operation
9) The bowl material is made of duplex stainless steel 2205 or 2304, the other bowl components are made of stainless steel 316L.The screw is made of stainless steel 304 by heat treatment up to 1000℃.The open impeller design can increase the fluids treating capacity. The collection box is made of stainless steel 304.

Fully Hydraulic Drive Decanter Centrifuge manufacture in China

As a professional FHD decanter centrifuge manufacturer in China, GN solids control produce both FHD decanter centrifuge and VFD decanter centrifuge. Fully hydraulic drive decanter centrifuge is new developed centrifuge compared with our mutual series VFD decanter centrifuge. Features of GN brand FHD decanter centrifuge as below:


1) Compact design, all the hydraulic drive system imported from Europe, the main motor ( explosion proof, IEC or ATEX), electric control panel, centrifuge bowl assembly, bearing , skid are installed on one skid for convenient operation, convenient transportation, and save space for installation.
2) Big bowl speed adjustment arrange, Big differential speed adjustment range for better separation result, it can treat the drilling fluids drier and recycle more clean fluids, and separate more solids.
3) It is more suitable for heavy duty drilling fluids and specially in high temperature area, like India, Middle east, Brazil, Africa etc. area.


GN VFD decanter centrifuge is also very suitable for extremely high and extremely low temperature area, like Russia, and above mentioned countries. When the environmental temperature is below 40 degree, the VFD self cooling tube installed inside the VFD control panel is enough. When the temperature is lower than 55 degree, we need to use an air conditioner for cooling, so that the VFD control panel can be operated 24 hours per day continuously without over heating to break. If use normal explosion proof VFD control panel, it will break very easy in hot weather.
The positive pressurized VFD control panel with stainless steel material cover, equipped with ABB brand inverter for main motor, back drive motor, pump motor, PLC smart control, HMI interface, the operator only need to connect the cable gland with the VFD control panel.
