We are going to ship 2 sets of shale shakers and one batch of shaker screens to South America, as the most professional manufacturer of shale shaker and shaker screens in China, GN solids control design and produce 2 panel shale shaker, 3 panel shale shaker and 4 panel shale shaker and dual deck shale shaker with different treating capacity.

We produce the OEM composite material shaker screens for our own shale shaker, we can also produce replacement shaker screens for world famous brand shale shaker, like Swaco Mongoose, Brandt Cobra, Derrick FLC 500, FLC 2000, FSI, KPT, etc. The shaker screens are packed in sea worthy pallet package which is container loading design.
Shale shaker is the most important equipment for solids control system, a good performance shale shaker can reduce the drilling waste volume effectively and reduce the cost of drilling waste management. When installed the hydrocyclones frame on the shale shaker, it will become the mud cleaner, desander cone, desilter cone and underflow shale shaker 3 in 1. By using different numbers desander cone and desilter cone, the treating capacity is different. GNZJ703F-1S8N mud cleaner with 500gpm treating capacity, GNZJ703F-2S12N mud cleaner with 1000gpm treating capacity, GNZJ703F-3S16N mud cleaner with 1500gpm treating capacity.
The order including 2 units of 3 panel linear motion shale shaker, we can also produce dual motion shale shaker with linear motion and progressive elliptical motion for different applications equipped with different vibration motors. The shale shakers are used to treat water based drilling fluids, it can be also used for SOBM and OBM. It can reduce the solids content and protect the centrifugal pump impeller, which will be easily damaged if the solids content is too high. The mud engineer will use different mesh shaker screens according to the drilling fluids conditions.

As the most professional shale shakers manufacturer in China, recently we shipped several units of shale shakers to our client for their repeat order. 4 sets of shale shakers are shipped to Asia client, 2 sets of shale shakers are shipped to South America. All of these shale shaker are with same model GNZS703F-SHBF.The technical features of the shale shaker are as below:

1) 3 panel screen, the shaker screen dimension is 700x 1250mm,composite material frame shaker screen , total screen area is 2.73m2
2) 2 ea of 1.72KW vibration motor, Italy Oil brand
3) 4 sides pretensioned shale shaker screen with heat press for longer working life and better separation performance

4) Heat treatment on complete shale shaker deck for High G force operation, G force is up to 7.5G which is adjustable
5) Shale shaker bottom deck made from Stainless Steel for long service life
6) Patent tighten rubber sealing for shale shaker deck and screen, long life and easy replacement.
7) Locking wedge to fix the shaker screen for fast screen replacement
8) Patent shale shaker deck angle adjustable while working, mechanical deck angle adjustment with reliable performance., deck adjustment angle is -1°~+5°
9) Feeding type: Weir Feede

Except for shale shaker, the client also order the shaker screens for stock. We can produce shaker screens comply with API RP13C from API 20 to API 300.We use 3 layers wire mesh for all the screens over API 60, and the wire mesh is from famous supplier SS316L.
If you need 4 panel shale shaker, 2 panel shale shaker, dual deck shale shaker, tandem shale shaker, triple shale shaker and dual motion shale shaker, pls contact with GN sales engineer. We also produce replacement shaker screens for other brand shale shaker, like Mongoose, Brandt Cobra, Derrick, FSI, Kemtron.

Recently we shipped solids vacuum pump to Africa client, the model is portable design GNSP-10B vacuum pump, it is the most popular model because of its compact design, it is easily to be installed and put into the oil tank and other tanks, GN vacuum pump can be also disassembled easily to be installed in the tank bottom and assembly again in the tank.

The solids vacuum pump can be used to transfer not only sludge, but also for animal waste, oil sludge, drilling waste, drilling fluids, chemicals, sand, oil contaminated soils, dredging sludge, mining slurry, waste water, cements and other powder materials.
It is 100% air operation pump without electricity power supply,

The client only need to prepare the suction pipe, discharge pipe and the air compressor.
The air supply demand and pressure required is as below:
For GNSP-40B, 17m3/min( 600CFM) , 80 ~114 PSI
For GNSP-20B, 8m3/min( 280CFM), 80 ~100 PSI
For GNSP-10B, 4.3m3/min(150CFM), 80 ~100 PSI

Why use GN solids vacuum pump instead of other pumps?
1) GN solids vacuum pump is air operation, no need electricity power, it is suitable for the area without electricity and hazardous area.
2) The max solids size is 75mm for GNSP40B and 50mm for GNSP-20B & GNSP10B, it is suitable to transfer the big solids without filter required.
3) Compact design, GNSP10B & GNSP20B are both made as portable structure, GNSP40B is also designed for easy transportation.
4) Powerful suction and discharge, the suction distance is up to 50m, the discharge distance ( horizontal) is up to 500m for GNSP-20B & GNSP10B, the discharge distance is up to 1000m for GNSP40B. The vertical lift height depends on the material, we will send the standard question list to know all the information and judge the possibility to use the vacuum pump.

As the offshore mud tank system manufacturer in China, we can design customized mud tank system for onshore and offshore drilling.
Recently we shipped one set of offshore mud tank system to our client, it consist of one unit of shale shaker, one unit of mud cleaner, one unit of decanter centrifuge , one unit of submersible slurry pump as feeding pump of decanter centrifuge, 2 units of centrifugal pump as feeding pump of mud cleaner desander cone and desilter cone. The shaker screen size of shale shaker and mud cleaner underflow shale shaker is same for easy stock of shaker screens, the composite material shaker screens is proved with at least 20% longer working life than the steel frame shale shaker.

Shale shaker is the first phase cleaning equipment to separate coarse solids and reduce the solids content, the performance of the shale shaker is better, the drilling waste is less, the working life of the desander cone is longer, the working life of centrifugal pump is longer.
The desander cone is the second phase cleaning equipment to separate cut point over 75 microns.
The desilter cone is the third phase cleaning equipment to separate solids cut point over 25 microns.

The decanter centrifuge is the fourth phase cleaning equipment to separate the fine solids cut point 2~5 microns. Features of GN decanter centrifuge:
1) Bowl material is made of duplex stainless steel 2205 or 2304 by centrifugal casting, the screw is made of stainless steel by heat treatment up to 1000 degree, the opening propeller design increase the treating capacity.
2) The solids discharge port and fluids distribution port is protected by tungsten alloy, the screw impeller is protected by tungsten carbide tiles, the scraper and side scraper is also installed to protect the solids discharge port and bowl.
3) The collection box is made of stainless steel material for better abrasion resistence.
