GN brand solids vacuum pump has been widely used to transfer different materials in different industry, like mud tank cleaning, crude oil tank bottom cleaning oil sludge, drilling cuttings for both onshore and offshore drilling platform, drilling waste, oil contaminated soil, sand, dredging slurry, industrial waste slurry, etc, it also can be used to clean the cabin, tank top and other drilling site area with the small model vacuum cleaner unit.

GN solids vacuum pump have 3 models for your option GNSP-40B with 40m3/h, GNSP-20B with 20m3/h, GNSP-10B with 10m3/h. The small size pump allowed solids size is max 50mm, max suction distance is 50m, max discharge distance is up to 500m, the max solids content is 80%; The Air Demand is 8m3/min (280 CFM).
The bigger size GNSP-40B pump with max allowed solids size is 75mm, max suction distance is 50m, the max discharge distance is 1000m, the max solids content allowed is 80%. Air demand is 17m3/min (600CFM).
The user should provide an air compressor for air supply to the vacuum pump, it is a 100% air operated pump, it is suitable for offshore drilling platform because electricity power is limited there. Compared with screw conveyor transfer system, vacuum pump can transfer much more long distance, no power consumption, less maintenance cost and spare parts cost, less cost, less space requirement, offshore drilling platform is normally with limit space, screw conveyor transfer system is hardly to be installed there, then several units of solids vacuum pump unit can be installed easily.
If you are interested in GN vacuum pump, pls contact with sales engineer and fill in the question list to check if it can be used or not. For working video and operation video of GN vacuum pump, pls check our website or get it from our sales: https://www.gnsolidscontrol.com/sludge-vacuum-pump

Recently GN has one unit of oil sludge treatment unit for sale, welcome to contact with sales engineer for more details. We have 3 models of oil sludge treatment unit with different treating capacity for option, 1 m3/h, 5 m3/h, 15 m3/h. The one we have in stock is 1 m3/h model. All the motor, control panels are explosion proof, suitable for application of oil & gas industry.

The configuration including: 1 ea pre-mixing tank with heating lines & mud agitator, 1 ea shaker tank with heating line and transfer pump, 1 ea 2 panel shale shaker, 1 ea mini decanter centrifuge, 1 ea centrifuge feeding pump, 1 ea disc centrifuge, 1 ea oil storage tank, 1 ea water storage tank, 1 unit of chemical dosing unit, pipelines and electric control system, all of the items installed one skid for convenient operation and land transportation.
The oil sludge treatment unit is used widely for Crude Oil tank cleaning sludge, Refinery plant waste oil sludge, Drilling waste oil sludge.
The working process is as below:

The sludge vacuum pump pick up the oil sludge from the waste pit to pre-mixing tank, ( for the compact unit with 1 m3/h capacity, the user dump the material to the pre-mixing tank directly by folk lift or crane ), the oil sludge is heating up to 60℃ to increase the flowability and make it easily to separate in the next process. The transfer pump will transfer the oil sludge to shale shaker to separate the coarse solids, the fluids dropped into the second tank which also equipped with heating lines inside, the decanter centrifuge feeding pump feed the fluids to decanter centrifuge to separate fine solids, the fluids flow to buffer tank, then flow to disc centrifuge to recover oil and water, the water and oil are storage into 2 box separately.

Recently GN solids control shipped several sets of mud cleaning system to North America for vacuum truck slurry treatment project, it can be used not only for vacuum truck slurry treatment project, but also for dredging slurry separation, mining tailings treatment, construction waste treatment, drilling mud cleaning, drilling waste treatment system, etc. projects.
The technical specification is as below:

Part 1: waste slurry collection hopper from vacuum truck to storage the slurry temporarily, there are 2 discharge port in the bottom of the hopper, so that the slurry can be fed to the 2 units of double deck shale shaker directly.

Part 2: mud treatment tank for coarse solids separation, including 2 units of double deck shale shaker, 1 unit of mud agitator, 1 unit of mud tank with pipelines, tank accessories.
Part 3: mud treatment tank for fine solids separation, including 1 unit of linear motion shale shaker, 1 unit of submersible slurry pump, 1 unit of mud cleaner, 1 unit of mud tank with pipelines, accessories, electric control system

Part 4: dewatering centrifuge package with chemical dosing system, centrifuge feeding pump, 1 unit of mud tank. To match with the treating capacity of the mud cleaning system, the dewatering centrifuge should be a big bowl decanter centrifuge, when used the chemicals or flocculants, the centrifuge treating capacity will be reduced a lot. The max centrifuge model we have is GNLW764A-VFD, the bowl diameter is 30 inch (760mm), the bowl length is 3328mm, the ratio of bowl length/ bowl diameter is 4.4 for better treatment performance. The max bowl speed is 2650rpm, the working speed is 0 ~2200 rpm, the max G force is 3000G, the normal G force is 0~2060G, with mechanical separation cut point is 2~5 microns, when working with chemical dosing system, the cut point is up to 1 microns.
