GN Solids America was funded in 2013, as branch of GN Solids Control, it main provide service to north and south America market for quick response. Not only a office , we also built warehouse in Houston to reduce the shipping time. GN main produce separation and conveying equipment for different industries, especially in the drilling, our equipment get good reputation with stable quality. Not only separation equipment, GN centrifuge pump,screw pump ,submersible pump these equipment as corollary equipment of separation system, they are also popular in the market, especially the vacuum pump.

Last week, we delivered several sets vacuum pump to Houston warehouse. It is different with the normal pump ,it used to transfer the material with high solids content or solids particle that smaller than 50mm, such as the drill cutting, waste water from mill, cement etc. Vacuum pump is driven by air. The transfer capacity can reach 10m3-40m3 depend on the material density and viscosity. Pump empty the air and generate suction force , the material will be suck in to pump body. Then the air compressor will convey high pressure to the pump and push the material to discharged port. The pump max suction distance can reach 50 meters, and max discharge distance can reach 500-1000 meters.It is long suction and discharge distance, but the pump suck depth is less than 12 meters in vertical. This limit some client to use it transfer sludge from deep pit.

As we know, only 3 companies in the world can manufacture this kind pump. And GN Solids America LLC is only vendor to provide this pump. Even so,GN price is very reasonable and competitive compared with some other pump supplier. With the widely application , GN vacuum pump are known by more and more people , we improved our inventory to make sure the quick delivery. If your project have demanded on this pump, please contact us.

GN Solids Control has been funded for more than 14 years. From the date of establishment, we are focused on the solid control industry and serve the drilling company and oil gas company , and help them solve the drilling mud treatment problem. In oil well drilling, the mud is very import middle material to cool the rig and carry out the drill cutting from well. It almost use the solids control system to finish this treatment.

As we all know, the mud system has several different kind equipment and mud tank. Which need many pump to transfer the the slurry from different tank. Centrifuge pump is the most common be used for in solids control system. At beginning, GN design the system ,and purchase the pump from other supplier for our solids control system. But the quality is not stable. Then we decider to make our own brand centrifuge pump with stable quality.

GN decanter centrifuge is one kind equipment with simple structure and stable quality. The pump connected with a electrical motor, through the motor drive the impeller to reach the slurry transfer. It can transfer the slurry with high solids content, but we need to note high solids content material will speed up the pump wear, especially the impeller. Centrifuge pump has not the ability that suck the material , the liquid level need to higher than suction port.

In the centrifuge pump , which has many spare part, so it will need supplier can provide the part quickly when client maintain the pump. Considered this point, GN decanter centrifuge spare parts are 100% interchangeable with Mission Magnum. Client can get the parts from GN ,or directly use Mission part. That will be convenient for client to repair the pump.

GN centrifuge pump have several kind model from 11kw-75kw with flow rate 45m3/hour to 320 m3/hour. Client can choose according to the requirement. For America user, you can directly purchase from our Houston warehouse and also the after sale service. GN centrifuge pump is stable with competitive price.

Hydrovac excavation is one popular in developed country. It utilized the high pressure water flush the ground and finish the excavation. Compared with normal excavation method, it is high effective, will not damage the pipeline under ground, and also the sludge will be sucked by hydro vac truck, so there is no pollution. However, the collected sludge always the big problem for treatment. GN dewatering system is specially used to treat this kind sludge. Last week ,we delivered 1 set dewatering system to our New Zealand client.

In this dewatering system, this will include mud catch hopper, coarse shaker ,mud cleaner and decanter centrifuge. As we know ,the sludge will be collected by hydrovac truck, the catch hopper make it easy that truck can directly dump the sludge into the hopper. It will improve the efficiency and prevent the splash. The catch hopper will feed the sludge into coarse shaker. The sludge always include some big solids ,such as gravel ,plastic, stone etc. Coarse shaker can separate out these big size solids, and finished the first stage of classify.

The liquid after coarse shaker will be feed into mud cleaner , through the the hydrocyclone , the solids that bigger than 40 micron will be remove out . In this step, the solids content will down to 20%. This is very import for the next separation stage by decanter centrifuge. Because the high solids content slurry will affect the working performance of decanter centrifuge.

In the final stage, the decanter centrifuge will separate out the solids smaller than 20um .Under the max 3000 G separation force, 95% solids will be removed. The discharged water is clean enough to reuse for the hydrovac excavation. This will save much cost of water. Meanwhile, the recycled solids can be used for building material according to the size. GN dewatering system is environment friendly, it get the good feedback from client to solve the sludge treatment problem , and recycle the water and building material to save resource.

We had built 11 sets dewatering system in North America, if you have demand ,welcome to contact us for more information.

Last week we shared part instruction how to disassamble the inlet pipe of decanter centrifuge, we will continue to share the following steps. Hope that will be helpful when you maintain your equipment. 

5. For thesmall end cover that has been removed , remove the receiving box and the fixing seat of the slurry inlet pipe .

6. Remove the sleeve of small end, take out the circlip, oil seal and bearing of the small end , and then install the small end sleeve in the original position.

7. Check the big end side of small end cover, and ensure bearing lubrication is good, no foreign matter, then replenish the grease.Install the small end cover according to the marked line.

8. Hoist the centrifuge assembly to the centrifuge base,put on the bolts, turn the centrifuge bowl by hand to make sure no scratching and abnormal noise. Install the positioning pins and tighten the bolts, turn the drum again to confirm that there is no abnormal.

9. Install the inlet pipe fixing seat and the receiving box in their original positions, and then the belts of main motor and auxiliary motor .

10. Install the upper cover of the collection box, tighten the bolts, turn on the equipment to see if there is any abnormality. After confirming everything is normal, install the inlet pipe, turn on the equipment again to confirm that there is no abnormal sound, scratch, etc., Install the motor shield, and start the equipment. Observe the work status, and check the bearing temperature . Commissioning with 4 hours idling to make sure no abnormalities
