Recently 2 sets of shale shakers are shipped to South America, together with 500 pcs shaker screens and other wear parts for stock. This is repeat order from the same client, they purchased 2 units of high speed decanter centrifuges before.


The shale shaker model is GNZS703F-SHBF, with shaker screen size is 700x1250mm, the total screen area is 2.63m2. The max G force is 7.5G and it is adjustable for different applications. The shaker deck angle is adjustable from -1º to +5º by manual adjustment. Both of the 2 sides can be adjusted synchronously. 2 ea Italy Oli vibration motors 1.72kw drived the shale shaker and the starter is explosion proof for oil drilling rig.
The composite material frame shaker screens is proved to work 20% longer time than previous steel frame shaker screens, in some rig site, the working life is up to 700 hours with drilling fluids. It can be also used for oil sludge treatment to separate the coarse solids from the oil sludge, different mesh shaker screens can be installed on the shale shaker by different applications. For all the mesh over API 60 use 3 layers stainless steel wire mesh for steady performance.
The decanter centrifuge model is GNLW363CG with max speed 3900rpm, The normal speed is 3200rpm for low gravity solids removal, the client can replace 2700 rpm speed pulley for high gravity solids separation or 2200rpm speed pulley or 1800 rpm pulley for barite recovery. The centrifuge bowl material is duplex stainless steel 2205, the other components are made of SS316L for better corrosion resistant, the collection box is made of SS304 material. The screw impeller is protected by tungsten carbide tiles which is repairable once it is damaged.

Recently 4 sets of solids control equipments are ready for shipment to our client, this is the repeat order from the client, they will produce 4 sets of mud tank system locally to produce sea freight cost and import tax. The configuration is as below:


1) 4 sets of shale shaker with 3 panel shaker screens, each shale shaker with 2 no vibration motors. Each shaker installed with API 170 shaker screens
2) 4 sets of 7.5KW mud agitators
3) 36 pcs of composite material frame shaker screens, dimension is 700 x 1250mm
4) 4 sets of mixing venturi hopper with stainless steel material
5) 4 sets of mud gun
6) 2 sets of centrifugal pump as mixing pump


These 4 sets of mud tank system are used for workover rig drilling mud recycling. Each mud tank with 1 unit shale shaker, 1 unit mud agitator, 1 unit mud gun, 1 unit of venture mixing hopper, 1 unit of centrifugal pump as mixing pump to drive the mixing unit. The client produce the mud tank, tank accessories, pipelines, walkways, handrails, stairs, valves, etc.


Compared with oil drilling rig solids control system, the workover rig mud tank system normally with less equipment and do not have strict requirement for the solids removal from the drilling fluids. The common rig solids control system including 2 or 3 units of shale shaker, 1 unit of mud cleaner with 2 unit of centrifugal pumps, 1 unit vacuum degasser, 1 unit of decanter centrifuge for barite recovery, 1 unit of decanter centrifuge for low gravity solids removal. Several units of mud agitator, mud guns for agitating the drilling mud, several units of mixing hopper with mixing pump, several units of charging pump to feed the drilling fluids to mud pump.

Recently one batch of solids vacuum pump are shipped to Africa. As the most professional solids vacuum pump manufacturer in China, GN solids control can produce 3 models vacuum pump with different treating capacity for different applications. We have 3 models vacuum pump for option: GNSP-40B with max flow rate 40m3/h, GNSP-20B with max flow rate 20m3/h, GNSP-10B with flow rate 10m3/h.


The vacuum pump is 100% air operated pump to transfer different materials, including:
1) Waste mud/ cuttings discharged from shale shaker, mud cleaner, decanter centrifuge
2) Drilling fluids
3) Oil sludge, oil tank bottom waste sludge
4) Dredging slurry/ mining tailings/ industrial waste mud
5) Barge holdings and vessel bottom cleaning
6) Sand, solids, fine silt, coarse solids
7) Hazardous waste/ oil contaminated earth
8) Animal waste


The GNSP-10B, GNSP-20B vacuum pump are all made as portable design for convenient movement, the actual flow rate will vary based on different materials transfer, for example, the flow rate to transfer oil sludge with high viscosity and to transfer normal sludge is very different. The user need to prepare air compressor for air supply and provide enough pressure. Also the client need to prepare proper length suction and discharge pipe to connect with the solids vacuum pump. The solids vacuum pump is the ideal equipment to transfer the solids with the most compact size without electricity power supply required.
GNSP-40B vacuum pump can be put on the trailer/ truck for convenient transportation.

Air supply demand:
For GNSP-40B, 17m3/min( 600CFM)
For GNSP-20B, 8m3/min( 280CFM)
For GNSP-10B, 4.3m3/min(150CFM)

Pressure required:
For GNSP-40B, 80 ~114 PSI
For GNSP-20B, 80 ~100 PSI
For GNSP-10B, 80 ~100 PSI

Max suction distance and discharge distance:
For GNSP-40B, 50m / 1000m
For GNSP-20B, 50m / 500m
For GNSP-10B, 50m / 500m

If you required the solids vacuum pump, pls contact with GN solids engineer.

Recently one set of offshore mud tank system is ready for shipment, Because of the limit space for offshore platform, the design of the mud tank system is compact and easy transportation, the technical configuration is as below:


1) One unit of linear motion shale shaker to separate the coarse solids, the shaker screens are composite material frame with stainless steel 316L wire mesh for longer working life, so that the user do not need to waste much time on replace the shaker screens. The screen lock method is by wedges with ratchet wrench for convenient locking the screens.


2) One unit of mud cleaner( desander cone, desilter cone and underflow shale shaker combination) with 2 centrifugal pump as feeding pump, the centrifugal pump is interchangeable with famous brand centrifugal pump, the hydrocyclones are 100% PU material for longer working life, if the mud temperature is higher than 80 degree, we will use metal cover outside the PU cone to prevent is from deformation.
3) One unit of decanter centrifuge with submersible slurry pump as feeding pump
4) Compact design mud tank with all the electric cables outside the mud tank for convenience replacement and check. The discharged solids/ cuttings are collected by a slant box and drop down to the screw conveyor to transfer the cuttings to the drilling waste management system.The user do not have to clean the floor and do not need extra skip to collect the waste cuttings. The handrail, walkway and stairs are installed with the mud tank.
5) The mixing hopper, mixing pump are installed on the mud mixing tank if the client need to prepare for new drilling fluids with the recovery drilling fluids.
If you need customized design mud tank system for offshore and onshore drilling, pls contact with GN solids control.

Last Month we shipped one unit of sludge vacuum pump to India for oil sludge transfer with capacity 40m3/h. This month the client repeat order again for a smaller flow rate 20m3/h vacuum pump, they need a smaller size vacuum pump.
When the client use the vacuum pump to transfer the oil sludge or tank bottom cleaning oil sludge, the real capacity will reduce according to different material. The higher density & viscosity of the material, the less transfer capacity it will produce.
The major components of a vacuum pump including:
1) Lifting frame
2) Vacuum tank and pedestal comnination
3) Air suction combination
4) Slurry suction pipe combination
5) Slurry discharge pipe combination
6) Air jet tube components
7) Air inlet pipe combination
8) Pressure pipe combination
9) Pneumatic control box


We will suggest the user to have one set of spare parts for their operation for convenient replacement once it is required.
What other accessories is required to operate the vacuum pump?
This is also the most common questions from our clients, they need to know the operation cost to use the sludge vacuum pump. There is pressure and air volume supply requirement for different model vacuum pump. Also the user need to prepare the strong enough suction pipe and discharge pipe with suitable length as per their own requirement. Our vacuum pump is 100% air operated pump without electricity power supply, the user need to prepare for suitable model air compressor. Before purchasing, we will send the question list to our client to judge if our vacuum pump can work for their project or not, especially for the suction depth/height, suction length and discharge distance.
GNSP-40B is the largest model we can produce right now, we can make customized design if the client need to put several units one one skid, the GNSP-20B, GNSP-10B vacuum pump is portable with compact design.
