As the reliable manufacturer of hydraulic drive decanter centrifuge in China, GN solids control recently shipped several units of Full Hydraulic Drive decanter centrifuge with feeding pump to Middle East, together with over 80 units of centrifugal pumps.


When we start production in the second factory in Dachang Chaobai River Development area, we introduced one batch of advanced machine to produce decanter centrifuge and vertical cuttings dryer, also for the centrifugal pump. We have high speed balancing machine, low speed balancing machine for balancing of centrifuge bowl. We can produce decanter centrifuge with 9 inch bowl, 14 inch bowl, 18 inch bowl, 22 inch bowl, 30 inch bowl for option, we have fixed speed centrifuge and VFD decanter centrifuge for different applications, also when used in high temperature weather area, for heavy drilling fluids, the user will need full hydraulic drive decanter centrifuge, compared with VFD decanter centrifuge, the hydraulic drive centrifuge is much easier to adjust the differential speed to reach better performance of the centrifuge treatment.


The feeding pump of the decanter centrifuge is positive displacement pump made by Germany Netzsch, it works steadily to feed the drilling fluids to the decanter centrifuge, the speed of the pump motor could be adjusted by PLC smart system so that the feeding flow rate will be controlled according to the client’s requirement.


4. The centrifugal pumps are widely used to transfer the drilling fluids, waste sludge, dredging slurry, oil sludge, etc. different materials and industry waste water. The major wear parts of the centrifugal pump is pump casing, impeller, the material of impeller and pump casing made by GN solids control is hard ductile iron alloy for longer working life and better wear resistance.
For more information about the full hydraulic drive decanter centrifuge, pls contact with GN solids sales.

Recently GN solids control shipped vertical cuttings dryer, decanter centrifuge system to Russia drilling companies, they are installed inside the 40ft container to keep them warm and avoid frozen of the drilling cuttings when working in Winter.


The client use the vertical cuttings dryer system for oil based drilling cuttings, when they use water based drilling cuttings, we will use different system design with high G drying shaker and decanter centrifuge, and we have standard design of pitless system for both water based mud and oil based mud ( also for SOBM), the client only need to buy one system and use them in different rig site.
The VFD decanter centrifuge GNLW363C-VFD is the most popular decanter centrifuge used for solids control system and drilling waste management system, oil sludge treatment system, dewatering system, solids water separation system and waste water treatment system. The VFD control panel is positive pressurized VFD control panel with PLC smart control and HMI interface, the inverter for main motor, back drive motor and feeding pump motor are made of ABB or Siemens brand or Schneider brand for global outsourcing.


The bearing is SKF brand, the screw  is made of stainless steel with heat treatment up to 1000 degree, the impeller is protected by tungsten carbide tiles for longer working life and easily replacement. The mud distribution port and solids discharge port are all protected by tungsten alloy and interchangebale. The bowl material is duplex stainless steel 2205 or 2304 by centrifugal casting, it is much better than SS304 and SS316.

GN solids control showed our equipments at Petrotech 2019 in India from Feb. 10th to Feb. 12th. The equipments we showed at the oil show in India including:


1) Sludge vacuum pump: it can be used to transfer drilling cuttings, powder cement, waste sludge, oil sludge, drilling fluids, industry waste water, mining tailings, dredging slurry, sand, even for animal waste, etc. Especially for high viscosity sticky oil sludge from refinery crude oil tank bottom, the vacuum pump is an ideal equipments to transfer the oil sludge, but the flow rate will be different with the normal flow rate. Depends on the different conditions oil sludge, we will choose the proper model for our clients according to the question list they filled.


As a 100% air operation pump, the vacuum pump do not need any electricity to operation, this is pretty convenient in some jobsites when electricity is limited, the user can use the air compressor in the jobsite to provide air for the vacuum pump, they can choose automatic operation or manually operation for their requirement.
2) Centrifugal pump: the complete centrifugal pump is consist of pump head, coupler for motor end, coupler for pump end, electric motor, control panel, skid and other accessories. The pump head is the most important components for the centrifugal pump, our pump head and all the parts are interchangeable with world famous brand centrifugal pump.
3) Shale shaker: the 2 panel shale shaker is the smallest model we have now, we have 2 panel, 3 panel and 4 panel single deck shale shaker for option, also we have dual deck shale shaker for special purpose.

GN solids control will ship 1800pcs shaker screens to our client in Asia after Chinese New Year holiday. All the screens are composite material frame shaker screens, the dimension is 635x1253mm. The screens can be loaded into 2 containers. Our factory will be closed for Chinese New Year holiday from January 29th to February 13th. Pls contact with GN solids control by email freely.


Shaker screens are one of our major products among our products lines. As the professional manufacturer of solids control equipments and drilling waste management, our products line including linear motion shale shaker, mud cleaner, desander, desilter, decanter centrifuge, vacuum degasser, centrifugal degasser, mud gun, mud agitator, centrifugal pump, submersible slurry pump, sludge vacuum pump, mud gas separator, mixing hopper and jet mud mixer, flare ignitor, screw pump, screw conveyor, high G drying shaker, vertical cuttings dryer, mud tank, complete solids control system and drilling cuttings treatment system. Also we can produce cuttings solidification unit, Thermal Desorption Unit, Oil sludge separation unit, chemical dosing unit, and HDD & CBM mud recycling system, TBM desander unit, Solids removal unit, Dredging slurry separation unit.


GN shaker screens are produced in our second factory workshop, every month we shipped thousands of shaker screens to USA, Russia, etc. over 70 countries in the world, most of them is from repeat order for good quality and competitive price. Features of GN composite material shaker screens:
1) All the screens over 60 mesh use 3 layers wire mesh for longer working life.
2) Four sides pre-tensioned shaker screens for reliable working performance.

GN solids control welcome our clients to take the sample materials to our facility to test by our decanter centrifuge, this is to let the client to know exactly the separation result clearly, and the operation method communication, this is a good way for the client to “watch the factory and watch the testing” before order.


GNLW224D mini decanter centrifuge is widely used to treat mining waste water recovery, industry waste water treatment, chemical slurry separation, animal waste separation, etc. projects. It is a single motor decanter centrifuge with VFD control panel, we can control the flow rate of the Netzsch brand screw pump by adjust the frequency of the motor, and set different differential speed to treat different fluids. The smaller of the differential speed, the drier of the discharged solids, the more clear of the discharged water. When increased the feeding flow rate, the discharged water might be less clear, the solids moisture is also increased. The max speed is 4500rpm, typical speed is 3800 rpm and the max G force is 2492G.


GNLW224EP-VFD is much better to treat the industry waste water, it is a 2 motor decanter centrifuge with main motor and back drive motor with VFD control panel. The smallest differential speed can be adjusted to 1 rpm, this can promise the discharged water very clear to meet the client’s requirement, and the solids moisture can also meet the limit. The max speed is 5000rpm, typical speed is 0~4500 rpm and the max G force is 3077G. The high G force ensures the better separation of the fine solids.
