Now there are hundreds of shaker screens manufacturers in the world, as one of most famous shaker screen manufacturers, GN Solids Control has a very good reputation for providing the most cost-effective replacement shaker screens. Based on the compare test, GN made shaker screens are even better than most of those OEM screens.
GN Shaker Screen product line includes replacement screens for Derrick 500, replacement screens for Derrick, replacement screens for Mi-Swaco Mongoose, and replacement screens for FSI, replacement screens for Brant King Cobra or Cobra and Venom etc. GN Solids Control is especially good at providing composite frame shaker screens. Now GN made composite frame shaker screens basically cover most of those above mentioned screens, some other screens are also can be provided by using composite frame.
GN Solids Control Houston warehouse stocks thousands of shaker screens which can be delivered to North America and South America in a pretty short period. Hundreds of oil and gas drilling rigs are using GN shake screens.
As one of the most activate oil and gas drilling area, Permian Basin has over 400 drilling rigs. GN Solids Control is working closing with many local shaker distributors. GN Solids Control provides shaker screens without GN logo so the end users will never know they purchase from us.
GN Solids Control hired one USA third party to test GN made shaker screens, based on the testing data they provided, GN made screens strictly conform to API RP 13C standard. Most of GN shaker screens competitors are using 2 layers for shaker screens below API 120, while GN Solids Control is using 3 layers for all screens above API 60. GN Solids Control is using the best quality shaker screen wire cloth providers which are similar as Mi-Swaco and Derrick. Feel free to connect with GN Houston office if you need any shaker screens.

GN Solids Control provides varieties of feeding pumps, like screw pump, submersible pump, centrifuge pump, shear pump, vacuum pump etc. Generally speaking, screw pump and submersible pump is used to feed decanter centrifuge, while centrifuge pump and submersible pump is used to feed hydro-cyclones.
Several weeks ago, we have one submersible pump issue occurred in South America. According the design principle: GN submersible pump will shut down automatically in order to protect the motor, which was designed and manufactured to run at 36A, 50A is too high.

We don't have extra motors for this pump. If you use higher running amperage, the power should be larger than 30Hp, which will increase the feeding volume and will affect the whole system separating process.
Desander pressure gauge was reading 25 psi, which is about 0.17 Mpa. What our team members did observe is that there are only 8 cyclones (pipes) on the desander, and 4 of the openings are plugged off. Our team members reviewed the spare parts but did not find any extra...
From the below guidance, appears we are about “spot on” regarding pressure…
adding in the 4 extra could potentially lower the pressure and potentially reduce some of the load on the pump?
Submersible pump to feed the fine shaker, so far so good! It does not shut down! We agree with the engineer, but so far that pump is doing fine. Will be even better with the agitators!
The pressure seems normal, need to discuss with our engineer and get back to you.
There are 8 sets cyclones assembled on the shaker. The rest 4 openings are blocked in order to control whole system treating volume, with more cyclones the treating volume will also get larger (4 sets cyclones will increase 500GPM treating volume). This is why we only use 8sets and didn't provide extra cyclones in the spare parts list.
At last we recommend modifying the impeller of this submersible pump. GN engineers recommend using one smaller impeller which is around 270mm.

GN Solids Control has provided thousands of solids and liquid treating units which are usd in various working sites to meet customers’ demands.
Today we would like to share another inquiry on GN Soil Remediation Unit. Here are the questions from our customer:
1. Does this system need a Pre-screening (or shaker type system), in the event large solids get pulled from the Tunneling operations (i.e. clay clumps, sand, nuts bolts, grease clumps, etc.)?
It's necessary to use one coarse shaker before feeding the slurry into decanter centrifuge if you have those large solids. We actually recommend the coarse shaker before. By using a coarse shaker (double deck or single deck depends on the slurry analysis), it will improve the separating performance of the centrifuge and also protect the centrifuge without too much wear from those large solids.
According to your former email, there's no large solids, please kindly help to double check. After treated by the decanter centrifuge, only few finer solids are left in the slurry. You may use one Inclined Plate Clarifier to removal them before release into the sewers. Or you may just use one holding tank in order to save cost.
2. Can you send a flow drawing of the complete system that shows the components included and any components that are needed that are not included?
Let's work on the system design first. A typical treating system will include: coarse shaker (depend on whether exist large solids)+ decanter centrifuge (necessary)+ dosing unit (necessary)+ inclined plate clarifier/ holding tank (optional).
For the decanter centrifuge +dosing unit, you may check those former drawings we sent to you before. Flow drawing can be provided after we confirm on what treating equipment will be needed.
GN Solids Control decanter centrifuge also provide Vibration switch to protect the two main bearings (also bearing temperature sensor), they can be fixed on the centrifuge as following decanter centrifuge we provided to Baker Hughes. They can both be integrated into our VFD control panel. Usually, they are provided when customer demands them. We have no problem to add them into your future unit.

GN Solids Control designs and manufactures various shaker screens. Until now, GN Solids Control made shaker screens are using in over seventy countries, which includes thousands of shaker shale shaker users.
GN Solids Control opened one branch company in Houston, TX. A large warehouse stocks more than 5000 pieces shaker screens in Houston, replacement shaker screens like Mi-Swaco Mongoose shaker screens, replacement Brant VSM 300 screens, replacement Venom or King Cobra Screens, replacement Fluid System Screens FSI5000 series. All of those screens are all composite frame screens. GN Solids Control has done some compare test in the drilling rig sites, it turns out most of the cases GN Composite Frame Shaker screens are even better than the traditional metal frame screens. GN Solids Control also manufactures replacement screens for Derrick 500 and Derrick 2000 series.
Since the opening of GN Solids America LLC, GN Solids has solids more and more shaker screens to North America and South America customers. Now many drilling companies are using GN Solids Control shaker screens in USA, Canada and Mexico. These days, GN Solids Control also got more and more inquiries from Latin America countries.
GN Solids Control would like to find some shaker screens distributors in Latin America countries. If you are using those OEM shaker screens, and you are tired of paying high shaker screen price, welcome to connect with GN Solids America LLC for more info.
GN Solids Control shaker screens now are also largely using in Latin American countries, such as Venezuela, Brazil, Trinidad etc. Before the oil price was very high, many drilling rigs stopped working, even those drilling rigs still working were trying to find the most cost-effective solids control equipment. GN Solids Control is a whole solids control and waste management system manufacturer. GN Solids Control shaker screens are also largely accepted by Latin America solids control service providers.
