As one of the leader in solids control industry. GN always try his best to develop and provide the best product to serve customer. Solids vacuum is GN most feature equipment for sludge transfer.

As we all know ,normal pump can not transfer the material with high solids content or high viscosity material. That makes some work very hard to transfer high solids content material. Most times client only can transfer these sludge by labor with low efficiency and high cost. To solve this problem ,GN develop this solids vacuum pump. Different with other type, it is driven by air, no impeller. Utilize the vacuum to suck sludge and push it by high pressure. Currently this pump is very popular and widely used in drilling industry, oil tank cleaning ,mining slurry transfer and powder material transfer. As long as more and more people know this pump, I believe it would be used in more different industry.

Last week, we shipped on GNSP-40B pump to middle east by air. This client provide crude oil tank cleaning service to local customer for many years. At the bottom of tank, there is always exist large oil sludge. They tried lots equip to remove them, but fail due to the high cost and low efficiency. They saw GN Solids vacuum pump in website ,after know their project situation. we recommend GNSP-40B pump for their project. Client want to suck out sludge from a 2 meters tank. These sludge almost solidified even client heat it up to 30 degree, it is still high viscosity with low liquidity. Solids vacuum is specially applied for this kind project. It 100mm inlet allowed the max 75mm particle through the pump and discharge it to finish the transfer. Drive by air means it is totally explosion proof, and comply with most strictly ex-proof requirement.

GN has 40,20,10B these 3 types with different transfer capacity. If your project have demand on these sludge transfer, welcome to contact us.We will be pleased to share our experience and provide equipment for your project.

WEFTEC is short of Water Environment Federation's Technical Exhibition, which is a professional exhibition of waste water industry. GN almost attend every year, meet our customer and communicate experience with other people in same industry.

In this time, we take our mini decanter centrifuge and solids vacuum pump to display. Mini Decanter centrifuge is our smallest model of Decanter ,which mainly used for mining slurry treatment such as diamond core drilling. Actually for waste water, our biggest Decanter GNLW-764 is suitable for big treating capacity. The bowl diameter is 760mm and the max capacity is 120 cube meter per hour. The big capacity make it very popular in waste water treatment.

One other our featured equipment is solids vacuum pump. This pump is different with normal pump, which is driven by high pressure air. Through the vacuum to suck and transfer material. It is good at pumping high solids content material or high viscosity material ,even some dry solids such as sand. Widely application in different industry, such as transfer oil sludge , suck tough sludge at the bottom of tank, transfer cement. Vacuum pump is one of the most feature products, which is very popular in all global market. Actually, its special application for high solids content material transfer, makes it no replacement device. In all over the world , there is only 3 company can built this kind pump, and GN solids control is the only China manufacture that provide it.

At WEFTEC, We also introduced out screw press dewatering machine and solids remove unit, but we did not carry the real to display. solid remove unit is specially designed for mining explore industry. It is a mobile unit, convenient for user to transfer it into different job site. The equipped shale shaker and Decanter centrifuge can separate the mining slurry well, but treating capacity is small.

GN has the design capacity for different complex separation project, if you have demanded on these project, welcome to contact us.

HDD is short of horizontal direction drilling, this is widely used in municipal project and also oil gas industry for pipeline laying etc. In most HDD project there will generate large drilling sludge, in some special project, these slurry also mixed much chemical medicine to improve the drilling efficiency and protect the rig. However these slurry is very expensive and also has big pollution to environment if we directly dump. Recycle the involved slurry in drilling sludge is very necessary to reduce the drilling cost and protect environment.

Last week we delivered one set HDD mud reclaimer to abroad project. This system include 2 unit GN mud recycle and one unit mud mixing tank. GN mud recycle unit is a small comprehensive system, which equipped GN shale shaker, hydrocyclone and also mud tank. This is double deck shaker, sludge was feed on the bottom shaker first, which can remove out the big size particle, liquid through shake screen and down to bottom tank. Centrifuge pump transfer slurry from tank into hydrocyclone, under the rotating liquid flow, solids will discharged from bottom of hydrocyclone , and recycled liquid will discharged out the system from top end, this discharged liquid is clean enough for reusing. Solids discharged from cyclone will drop on top layer shaker screen. This screen is higher mesh to separate out small size particle, liquid go through top and bottom shaker screen , finally down to bottom tank. Centrifuge pump it again into hydrocyclone. After a entire loop treatment, we get clean slurry and dry solids.

In this project, we also customized produce mud mixing tank for client mad drilling mud. From photo you can see it has big tank to store cleaner water and also a feeding hopper. Pump water from tank, through venturi principle, chemical medicine will be feed from hopper and mix with water. This design is convent for client to supplement new mud when they need.

GN has more than 15 years manufacture experience in separation equipment.If your project have demand on this kind equipment ,welcome to contact us.

In Latin America and south America, such as Peru ,Chile, Mexico etc. The mining industry of these country is very developed. However ,in the mining process, which will use large water to flush the mining ore , and genera large slurry. Which is high pollution , the sludge with long time accumulation, the quantity is huge. Almost every mining have a huge sludge pit. It is very necessary to treat these sludge ,and recovery the oil.

Last week , we receive inquiry form Peru customer in mining. They have a big issue of sludge in their mine. This customer want us provide solution to process these sludge , otherwise they have to built a new job site for the mining.Client require us recovery the water and dewatering the solids. The recycled water will be reuse for mining, and the dried solids will be transport to landfill near the job site. It is a huge treating capacity ,in the rainy season ,the flow rate can reach 360 cub meter per hour, 30% solids content , particle size centralize over 400 um. For this project, we need to use the big capacity equipment.

Firstly, GNZS595 shaker screen. 3 units shaker, the treating capacity can reach 140m3/hour. It will equipped PU shaker screen to anti wear for long lifetime. In this process, the particle bigger than 400 um will be remove out. And then the discharged liquid will be feed into GNLW764 decanter centrifuge. Which is the biggest mode centrifuge of GN, every hour can treat more 120 cub meter slurry. In this process, the particle size bigger than 5um will be separated out , and it does not need to add any chemical medicine. The moisture of discharged solids will less than 40%, which will dry enough for landfill without any liquid leakage. Water will be stock for mining.

GN has series equipment for waste management , and provide the technical support. If your project have demand on these separation equipment, we will be please to share our experience.
