centrifugal pump

This week GN solids control shipped one batch of mud transfer pumps and mud agitators to Asia client. The centrifugal pumps are 100% interchangeable with world famous brand centrifugal pump, we can provide bare pump head and all the parts and the whole centrifugal pump with motor, skid, coupler, and control panel.


Features of GN centrifugal pump:
1. The impeller and pump casing is made of hard ductile iron alloy, which is abrasion resistant material and can longer the working life of the centrifugal pump. Different with the other competitors grey steel material, it is easily break.


2. The bearing is top brand bearing for reliable operation, the client do not need to repair the pump time and time and delay their operation.
3. The mechanical seal is also an important wear parts for the centrifugal pump, for better sealing and zero leakage and longer working life.
4. The mounting skid of the centrifugal pump is made from casting instead of welding to provide the reliable operation and less vibration for longer working life.


Mud agitator is one of the mixer equipment to be installed on top of the mud tank, together with tank bottom mud gun for better agitating and mixing of the drilling fluids in the mud tank, to prevent the drilling fluids to be accumulated in the tank bottom. The direct connection mud agitator design is with compact size, convenient operation, maintenance and customized agitator shaft length and impeller size for better performance.

10 units of shale shakers are shipped to India drilling company this week, they also produced one set of solids control shale shaker tank ready for shipment, including 3 units of same model shale shaker, 1 unit of mud cleaner, 1 unit of vacuum degasser, 1 unit of mud gas separator, 2 units of centrifugal pumps, and necessary mud agitators, mud gun, and 1 unit of mud tank.


GNZS703F-HB shale shaker is one of the best sold model shale shaker, with 3 panel composite material frame shaker screens, we produce OEM shaker screens in GN own shaker screens workshop. Except for the OEM shaker screens, we also produce durable composite material shaker screens for world famous brand shale shaker, like Derrick FLC 500 series, FLC 2000 series, hyperpool, D600, etc, Brandt King Cobra / Venom, VSM300, MI-SWACO Mongoose PT,MD 2/3, FSI, etc. Compared with the steel frame shaker screens, GN made composite material shaker screens with 20% larger effective screen area, the working life is much longer, the storage period is up to 5 years.


The mud cleaner is the combination of desander cone, desilter cone, underflow shale shaker, the treating capacity is different by using different quantity desander cone and desilter cone. GNZJ703F-1S8N with 500gpm capacity with 1ea desander cone and 8ea desilter cone. GNZJ703F-2S12N with 1000gpm treating capacity with 2ea desander cone and 12ea desilter cone. GNZJ703F-3S16N with 1500 gpm treating capacity. The feeding pump for mud cleaner is GN made centrifugal pump , the parts and installation dimension is 100% interchangeable with world famous brand pump.

This week GN solids control shipped one unit of HDD mud recycling system and dewatering unit to Sinopec project. HDD is one of our major applications, GN equipments 4 major applications including oil & gas industry solids control system and drilling waste management system and oil sludge separation system, HDD & CBM industry mud recycling system, Piling & TBM desander unit, Industry waste water treatment.


The technical configuration is as below:
1) 3 phase cleaning mud recycling system mud tank, with containerized frame for convenient transportation, the user can put the mud tank and the frame with equipments on the trailer and move to another site from one site.
2) 1 unit of GNZS703F shale shaker as the first phase cleaning equipment, equipped with 3pcs of durable composite material shaker screens with customized API mesh screen. We produce OEM composite material shaker screens from API 20 to API 325 as per client’s requirement.


3) 1 unit of GNZJ703F-1S8N mud cleaner, with under flow shaker, desander cone and desilter cone combination unit. Equipped with 2 units of centrifugal pumps as feeding pump of desilter cone and desander cone.
When the drilling fluids temperature is over 70 degree, we will use special material hydrocyclones for longer working life.
4) Dewatering system with same dimension mud tank
5) Decanter centrifuge GNLW363C-VFD is the 4th stage cleaning to separate fine solids smaller than 15 microns. After several years working, more and more fine solids are accumulated in the tank bottom, these fine solids can not be separated by the desilter cone, then high speed decanter centrifuge is required to clean the drilling fluids, otherwise it can not be reused for drilling again.

56 units of drilling fluids mud agitators and 3 units slurry vacuum pump shipped to China client this week.
The mud agitator is consist of electric motor and gearbox and skid, it is installed on the mud tank to prevent the solids from accumulation on the tank bottom. The mud gun length and mud agitator shaft length is customized according to mud tank inner depth. GN mud agitator have C version and D version, the C version mud agitator is that the electric motor and gearbox is connected by coupler , if the client need local standard motors or they want to install their own motors, they can buy the gearbox with coupler and skid, and install the motor locally to meet the special explosion proof standard. D version mud agitator is the lastest mud agitator, the gearbox and electric motor is connected directly, with compact design, it will save space on the mud tank, and easy for maintenance.
The slurry vacuum pump is the most popular drilling cuttings transfer pump since this year, with the advanced technology. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer. The pump can transfer material with high gravity and high density, solids content max. up to 80%.
GN solids control can offer various pumps, including submersible slurry pump, centrifugal pump, screw pump, vacuum pump for different applications. Vacuum pump is our new products, we already sold it to many jobsites in the world.

 

GN Solids Control is a world-famous company specializing in manufacturing drilling mud solid control and waste management and recycling. Its product range covers shale shaker, desander, desilter, vacuum degasser, decanter centrifuge, cutting dryer, centrifugal pump, screw pump and so on. Its products are mainly used in oil and gas drilling, civil works(like piling, TBM, HDD), and mining industry.

                 

In the oil and gas drilling application, there is one important equipment in the solid control system, that is vacuum degasser. It is usually used after the shale shaker and before the mud cleaner. The main application of the degasser is to eliminate the gas immersed in the drilling mud, which will help restoring the mud weight, stabilizing the slurry viscosity, reducing the drilling cost, and preventing the well blow out accident. The vacuum degasser is mainly composed of vacuum tank installed on a skid base, vacuum pump, gas water separator, control panel, explosive proof motor. Its working principle is that: under the effect of the suction power from vacuum pump, negative pressure zone will be generated in the vacuum tank, and the drilling mud will enter the hollow shaft of the rotor through the suction tube under the effect of the atmospheric pressure. Then the mud will hit the windows of the hollow shaft and be sprayed to the wall of vacuum tank. Under the collision effect of the separation baffle, the mud will be separated into thin layers, and bubbles immersed in the mud will be broken up and comes out. The gas will be discharged by the vacuum pump and gas water separator to the safe zone, the mud will be discharged outside of the tank by impeller. In the whole process, the rotor will keep running at high speed under the power of main motor.

 

Now GN has two kinds of vacuum degasser: GNZCQ270A and GNZCQ360A, the processing capacity for these two equipment is 270m3/h and 360m3/h. Welcome to visit www.gnsolidsamerica.com
