decanter centrifuge

This week 2 units of VFD decanter centrifuge ready for shipment to India for ONGC project in GN factory. The clients ordered 2 units of GNLW453C-VFD with screw pump for their solids control system with their customized painting color.


GNLW453C-VFD centrifuge with 18inch bowl and 61inch length, the max G force is up to 2578G, considering the high temperature in India, the positive pressurized VFD control panel with air conditioner for cooling, in some countries with environmental temperature less than 40 degree, the VFD control panel attached cooling tube for cooling. The frequency converter of the main motor, back drive motor and pump motor is all made of ABB brand, the other electric components are also world famous brand like Siemens/ schneider/ ABB, the motor and VFD control panel are all ATEX approval and suitable for 460V/60HZ, 3 phase and apply for zone 1 application.
Features of GN decanter centrifuge:
1) Different with other Chinese centrifuge manufacturer, GN use SKF bearings, since bearing block is the most important part for centrifuge, we use more reliable brand bearing to improve the centrifuge working life and reduce maintenance cost.
2) The screw is completely made of stainless steel, the impeller is protected by tungsten carbide tiles, the fluids distribution port is protected by tungsten alloy and interchangeable.

This week GN shipped one set of containerized drilling cuttings treatment system and several units of shale shaker to Russia. This is not the first containerized drilling cuttings treatment system sold to Russia, because of the low temperature in Russia area, the client do not want to stop operation in the long winter, this customized design is to keep the drilling fluids warm and prevent it from get frozen.


The containerized drilling cuttings treatment system including one unit of vertical G dryer with fluids collection tank, one mud agitator installed on top of the collection tank. The centrifuge feeding pump transfer the mud from fluids collection tank to the decanter centrifuge to separate more solids from the fluids, the final discharged solids can be reused for the drilling rig or used to prepare for new drilling fluids. The solids discharged from the vertical G dryer is with OOC < 5% like powder, they will be transferred by the screw conveyor to the cuttings box outside the container. One unit of 4kw screw pump is used as flashing pump of the vertical G dryer. The whole drilling cuttings system treating capacity is 40m3/h for oil based drilling cuttings, the decanter centrifuge with VFD control panel can be used to separate the fine solids from the fluids, the separation cut point is 2~5 microns.


The client also ordered several units of GNZS594 shale shaker with 4 panel composite material frame shaker screens, the screen size is 585x1165mm, the total screen area is 2.73m2, the G force is high up to 7.5G.

After participation in the CIPPE 2018 in Beijing, China from 27th to 29th March, 2018, GN solids control will participate in OTC 2018 in Houston , TX.

Decanter centrifuge GNLW363C, this is the best sold model decanter centrifuge among all the decanter centrifuge models.
Shale shaker: GNZS594F-HB, we have many sets of shale shaker and mud cleaner in stock in Houston warehouse for immediate shipment, we install Martin brand vibration motor made in USA and assembly in our warehouse.
Sludge Vacuum pump:GNSP-20A, this is our new products in 2018, we have sold GNSP-40A vacuum pump for drilling cuttings transfer and dredging slurry transfer for dredging slurry separation system, sometimes the vacuum pump may not be suitable to transfer the oil sludge based on the sludge density and viscosity and the depth. GNSP-10A & GNSP-20A vacuum pump is the new designed model to meet the client’s requirement for smaller treating capacity.


Mud cleaner: GNZS594E-2S12N
Centrifugal pump, the installation dimension, outer dimension and spare parts are all interchangeable with Mission Magnum centrifugal pump.

If you are looking for a good manufacturer of decanter centrifuge, vertical cuttings dryer, shale shaker, shaker screens, welcome to visit GN solids control stand at CIPPE 2018 to check our equipments.
Our stand info is as below:


We will show our best sold model decanter centrifuge at the show. As the largest and most professional oilfield industry products and service exhibition in China, all of the manufacturers will show their most advanced technology during the show.


GNLW363CG-VFD decanter centrifuge is one of the best sold model for our international clients, it can be used for solids control system, drilling waste management system, industry waste water treatment, dredging slurry separation, dewatering system, barite recovery, Low gravity solids separation, etc.
GNLW553C-VFD decanter centrifuge is the best sold big bowl big volume centrifuge, it is normally used as dewatering centrifuge with chemical dosing system for waste water treatment, it can be used for all kinds of waste water treatment. Sometimes it is used for oil sludge treatment system when the clients need 20~25m3/h treating capacity.


We will also show vertical G dryer GNCD930, it works together with GNLW363CG-VFD decanter centrifuge as drilling cuttings treatment system for oil based mud.
