1 unit of GNLW363D decanter centrifuge,the working principal of the decanter centrifuge is as below:


The centrifuge bowl and screw rotates in same direction with a set differential speed, the feeding material is transferred by the centrifuge feeding pump continuously into the screw shaft, then flies to the bowl along with high speed increase. Under the working of centrifugal force, the heavy phase solids deposite on the bowl wall to form sediment layer, the solids is pushed the bowl cone section and discharged from the solids outlet. The light liquid phase forms a liquid ring, which is continuously overflow out of the bowl from the liquid outlets at the big end of the bowl. The straight section of the bowl is the clarification area, and the cone section is extrusion drying area. The decanter centrifuge separation cut point is 2~5 microns, with proper chemicals additives, the separation cut point is up to 2 microns. The centrifuge bowl diameter is 360mm, the bowl length is 1271mm, the max speed is up to 3900rpm, and max G force is 3063G, the designed capacity for water is 200gpm, and typical capacity is 132gpm, the main motor is 50HP, back drive motor power is 15HP.

Recently one batch of vacuum degasser, decanter centrifuge, solids vacuum pump and shale shaker are ready for shipment for international drilling company.


The vacuum degasser model is GNZCQ270B horizontal type vacuum degasser, which is self suction type without needing a jetting pump. It has been widely used to separate gas from gas cut mud, so that it can protect the solids control equipments used in the next step, such as centrifugal pump ( desander desilter feeding pump). The vacuum degasser will be normally installed on the mud tank which is after primary shale shaker and before desander desilter or mud cleaner.
The features of GNZCQ series vacuum degasser are as below:
(1) water ring type vacuum pump provide safe and reliable operation.
(2) Suction capability of the vacuum pump plays 2 roles, 1 is to let the mud entering in, 1 is to let the gas out of the vacuum tank, it means, the working of the vacuum degasser do not need an extra jetting pump.
(3) When there is no gas cut mud, since the suction pipe is installed inserted into the mud tank and under the liquid, it can be used as high power mixer of the drilling mud.
(4) Belt pulley instead of gearbox for easier maintenance.
(5) Proper design of gas water separator, since the gas and water will not be discharged simultaneously, the exhaust pipe will be always unconstructed, the water can be circulated as water supply to the vacuum pump for less water consumption.


The solids vacuum pump can be used as spilled mud collection on the rig floor, or transfer pump of the drilling fluids, drilling cuttings and other high solids content materials from one place to another place. The rig air supply can be used as the vacuum pump air supply, it is a 100% air operated transfer pump without electricity.

What equipments and technology we will show at IE expo China environmental show?
The subject of our show is related to oil sludge treatment equipments and solids liquid separation equipments.

Sludge Dewatering Centrifuge
GN T series decanter centrifuge is mainly used for dewatering and thickening purpose. It has been widely used for municipal and industrial waste water treatment. Normally it needs to work with flocculants to gather the fine solids condensed into large solids in the waster water or sludge, then dewatered with GN T series decanter centrifuge.

Solids vacuum pump, GN solids vacuum pump is a 100% air operated pump to transfer drilling mud, hazardous waste, barge holdings and vessel bottom cleaning, sand, animal waste, bulk tank and silo transfer, oil sludge, tank bottom residual removal, waste pit cleaning, drilling waste, diatomaceous earth, etc. Especially when the transfer distance is up to 1000m, and the solids content, high viscosity, and max solids size is up to 75mm, or when electricity power supply is not available, vacuum pump will be an ideal solution.

Vibrating screen, it is used to remove the coarse solids from the sludge before feeding to other solids liquid separation equipments.

Waste Treatment Decanter Centrifuge, it is used for oil water solids separation in oil sludge treatment system.

Recently a unit of mute solids vacuum pump are ready for shipment, it will be used for tunneling slurry transfer. The vacuum pump is used to suck the slurry used for Tunneling project and discharge to another place, the max suction distance is 50m horizontally, max discharge distance is up to 1000m horizontally. The vertical lifting depth is up to different materials. The max solids content allowed is 80%, and max solids size can be pumped is up to 75mm, it can be used to transfer tunneling slurry, especially for long distance transfer. Since the vacuum pump is 100% air operated pump, no need electricity supply, it is suitable for hazardous area application. When the vacuum pump is installed near city center, a mute tank is applied to reduce the noise.


Tunneling slurry is a mixture of topsoil, Portland cement, and water. The consistency of the slurry is different depending on its purpose in a repair project. The slurry is made thinner and more watery for filling purposes and thicker with less water for lifting purposes. In foundation repair and tunneling, slurry is used as a filling material and is of a thinner consistency.


We have 3 models of solids vacuum pump for option with different flow rate, GNSP-10B with flow rate max 10m3/h, GNSP-20B with max flow rate 20m3/h, GNSP-40B with max flow rate 40m3/h. There are automatic mode working and manual mode working for option based on different working conditions. After several times testing for suction time and discharge time, the user can adjust the timers of suction and discharge until it reach your requirement.
It can be widely used to transfer waste mud, drilling cuttings, oil sludge, tunneling slurry, animal waste, hazardous waste, sand and solids, etc. material. If you need solids vacuum pump, pls contact GN solids control.
