Last week we delivered 1 unit GN vacuum pump to northern America client. This pump will be applicant on the chemical industry. Vacuum pump was totally self developed by GN. And we are the only China manufacturer that can provide this vacuum pump.

The most type pump of the market are for water or some material with lower solids content. But for some high viscosity or high solids content, normal pump is useless. Many our client from oil gas industry was troubled when transfer drilling cutting, oil sludge ,or the settlement on bottom tank. Aim at these problem, GN manufactured this vacuum pump. It is different with normal type. The power is from high speed pressure air. Vacuum pump equipped a venturi device, when high pressure pump flow through venturi, the air flow will take air out from inside of pump tank, and generate a negative pressure space. Suck material inside pump tank. Higher pressure air supplied, higher suction generated. In theory, the suck distance can reach 100 meters.

This pump is automatic machine. The loading time and unloading time are controlled by a timer delay switch. Operator can setup the suction time from 5seconds to 30 seconds and also same unloading. For currently, we have 3 models according to treating capacity, 40B, 20B, and 10B. The number of model standard the treating capacity ,such as 40 B means 40 cube meter per hour. The pump standard material is carbon steel, if client have special requirement, we also can provide 304 stainless steel and 316 stainless with anti corrosive. This pump can not transfer material include chloridion. Because it will corrosive steel and damage pump.And the pump is high pressure container, any damaging is not allowed.

GN Export more than 100 units vacuum pump every year, especially mining slurry industry, this pump is very popular for slurry long distance transfer, and stable quality. If you are interested in our pump, welcome to contact us.

In generally , offshore drilling equipment has more strict requirement to equipment quality, and manufacturer need to produce with higher grade standard. Such DNV lifting ,footprint designing, higher explosion proof standard and also the anti corrosive coating. To reach these quality standard ,manufacturer need to have full experience. GN has focused on solids control equipment for more than 15 years .We exported to more than 75 countries and provide equipment to many top oil gas industry in the global. Such as Baker Huges, Shell, Halliburton etc. GN get his reputation from the market.

Last week we delivered several set cutting drying high G shale shaker to offshore drilling platform. It different with normal shaker. This high G shaker was used to treat drilling cutting. The vibration G force can more than 8 G.  Through the shaker treatment , we can recycle partial drilling mud and dryer cutting to convenient transporation. It is helpful to reduce transport cost and for the further process. As we all know drilling mud is high solution ,even the drying drilling cutting to be treatment by profession device to reduce pollution.

From the photos we can see, this high G shaker equipped a vacuum device. It connect with a liquid catch hopper installed under the shaker screen. The vacuum device can generate negative pressure. When drilling mud pass this area, the negative pressure will suck liquid out drilling cutting and dryer it. This special equipment is very popular, and it has been used in many drilling job site. Currently GN can provide two models cutting dryer shaker. One is installed 4 pcs shaker screen ,and the other is equipped 3 GN shaker screen. They have similar capacity ,which can recovery 2000L mud per day.

GN can provide a whole series solids control equipment and wast management equipment for drilling industry. We are good at customized build system according to client requirement. If your project have demanded on these equipment, welcome to contact us.

Solids control of oil gas industry is just one branch of solids liquid separation. Although is famous with its solids control equipment in the global market, but GN also provide equipment for other industry ,such as waste water treatment from municipal project, such as slurry from HDD, TBM. The most featured product of GN is shale shaker. According to the treating capacity and different application, GN has 2 panel ,3 panels, 4 panels and double deck shale shaker.

Shale shaker is the primary separation equipment in waste water treatment. though the vibration, shale shaker can generate 7-8 G force, The solids smaller then screen opening size will go through it and down to bottom tank, certainly the water will also through the screen and be collected together with fine solids. The bigger size particle will be separated out and discharged out the shaker. Considering the treating capacity, most shale shaker consider to use the screen that mesh smaller than 270. Since the higher mesh will reduce the treating capacity, because the higher mesh meander the smaller opening size, even the water is harder to go through.

To get more clean water, we can mount hydrocyclone on shale shaker. 10 inch diameter hydrocyclone and 4 inch hydrocyclone. We call the combination unit as mud cleaner. The liquid discharged from shaker will be pumped into 4 inch hydrocyclone ,the flow under the high speed will generate separation force, the solids bigger than 40 um will be separated out. And we can get the clean water. From this photo we can see, there is also equipped a 10 inch hydrocyclone ,actually the sludge will feed into 10 inch hydrocyclone as the first step separation , and then shale shaker, finally 4 inch hydrocyclone. We designed the bottom tank as buffer to collect liquid from shaker. This is a customized design.

GN is good at provide customized solution for client special requirement. If you have demand on these separation equipment ,welcome to contact us.

As long as there are more environment protection laws issued in different country. All global company are upgrading their device to reduce the consumption of resource and also the output of pollution. Water consumption and waste water treat is the most gravely problem for all people from different industries. Our Australia client also faced the same issue. They are a construction company, most of their project need large water and also lots wasted water need to be treatment for reuse or discharge after reach emission standard. To construction company, the wasted water always mixed with kinds solids, if we can clarify them, we can reuse it.

Last week we shipped one set solids liquid separation equipment to Australia, as we all know Australia has the most strict law rule about waste treatment. This system is main used to process the waste water from construction, which mixed with vary size particle. From the picture we can see the main equipment was loaded in sea container. Due to client frequently change the job site , the container package is convenient for customer to transport them between different place. Aim to the big treating capacity requirement and complex solids content. We add the liner mining vibration screen. As usually, this shaker was used in mining industry to dewatering mining slurry, big capacity and anti-wear. Sludge can be directly feed into this mining shaker to remove out particle bigger than 1mm. after that, liquid will be pumped into GN liner shale shaker to remove out solids bigger than 100um. It is the featured shaker of GN, we exported more than 200 units to different country all over the world, and it get the good reputation from the market. After the treatment by both shaker, it will be feed into hydrocyclone and Decanter centrifuge to remove out the fine solids. After the whole treatment program, we can get the clean water for reuse in construction project or directly discharge.

GN can provide different kind solution as client required, customized manufacture the separation system, if you have demanded, welcome to contact us.
