vacuum pump

Recently one set of oil sludge treatment system is ready for shipment to a oilfield environmental solutions company with customized painting color. GN solids control can design and produce standard oil sludge treatment system with different treating capacity 1m3/h, 5m3/h, 15m3/h, also we can design as per client’s concept and technics process.


A standard oil sludge treatment system is consist of the modular below:

  1. Waste transfer unit: GN use our own solids vacuum pump to transfer the oil sludge from the waste pit to pre-mixing modular. The features of vacuum pump: (1)100% air operated pump without using electricity power, need air compressor for air supply. The user need to prepare one air compressor to provide air for both vacuum pump and the positive pressurized VFD control panel of the decanter centrifuge.
    (2) can be adopted to different types of oil sludge, heavy duty for continuously working

  2. (3) automatically and manually working for option for different requirement
    (4) max discharge distance is up to 1000m, max suction distance is 50m, it can used into the crude oil tank without labors in, it is user friendly pump to transfer the oil sludge out of the crude oil tank bottom.
    2 pre-mixing modular: including a pre-mixing tank equipped with heating lines inside the tank wall, when the user supply hot steam to the heating lines, the oil sludge will be heat to 60 degree for easier separation in the next separation step. Mud agitator with control panel to agitate the oil sludge with necessary chemicals and keep it flowable. The submersible slurry pump will transfer the pre-mixing oil sludge to the next process- coarse solids separation modular.
    3 coarse solids separation modular: it might be removed depends on if there is coarse solids in the oil sludge.
  3. fine solids separation modular for solids/ liquid separation by using VFD decanter centrifuge, and working together with chemical dosing system
  4. 3 phase centrifuge modular to separate oil from water.

GN solid control will participate in the exhibition 2019 ADIPEC in Adu Dhabi again this year, this is one of the biggest and most important exhibition for oil and gas products & service, we had participated in this exhibition every year. The general information is as below.

3) Decanter centrifuge: GN made high speed/VFD decanter centrifuge has been widely used for oil & gas industry solids control and drilling waste management, dewatering unit, construction waste treatment, oil sludge treatment, dredging slurry separation, and waste water treatment, including mining tails separate.


4) Vacuum pump: The vacuum pump can be used to transfer different materials like drilling cuttings, dry sand, cement, drilling fluids, slurry, oil sludge, contaminated soils, dredging slurry and all other kinds of sludge.
If you are interested in these products and would like to know more, welcome to visit GN stand at ADIPEC.

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

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.

GN Solids Control finished the oil exhibition at OTC 2019 in Houston, TX successfully. We have showed both of our traditional equipments and new technology at OTC. Centrifugal pump, Decanter centrifuge, shale shaker and composite material shaker screen are most popular products among our complete products line, which have been sold to over 70 countries in the world. We can provide OEM shaker screen for our own shale shaker and replacement shaker screens for world famous brand shale shaker. The composite material shaker screen working life is proved much longer and with larger screen area.


The new technology ViST vacuum screen, Sludge vacuum pump are introduced and many clients showed interests on them. The ViST unit are used together with the shale shaker, the purpose is to reduce drilling waste and recycle more drilling fluids. You can check the working video from GN website: http://www.gnsolidscontrol.com/video/vist-vacuum-screen-technology-for-shaker-test-video


It is installed under the last screen of the shale shaker or mounted externally whichever is convenient. The ViST increased the recovered drilling fluids volume and drier cuttings of the drilling waste. The less drilling waste is produced so the cost to treat the drilling waste is reduced. The operator can save money for drilling fluids and treat drilling waste.
The vacuum pump is not a new product, It has been widely used to transfer the oil sludge, waste oil, drilling cuttings, cements, dredging slurry, waste slurry, etc.


Both of the vacuum screen and vacuum pump are air operated, no need electricity power. It is convenient when electricity power is limited. The air compressor is required to provide the air.


We can also produce and customized design the tank cleaning system, waste water treatment system, complete set oil sludge separation system, drilling waste management system, mud recycling system and solids control system. For more information, pls contact with GN sales engineer.
