Recently, GN finished the fabrication of a batch solids control equipment ordered by an oilfield service company from Venezuela. More than 10 units drilling mud centrifugal pump are part of the order and already packed waiting for delivery.
In drilling mud recycling system, the centrifugal pump is a type of very important equipment that is always used for drilling mud transferring. There are several applications of the centrifugal pump as below.

Centrifugal Pump used for feeding to cyclone unit
Normally is the solids control system, de-sander, de-silter andmud cleaner would be used to remove fine solids. Centrifugal pump could be used to suck the mud after treated by the shale shaker, and send to the de-sander and de-silter cyclone. In the meanwhile, the centrifugal pump gives the power or pressure for mud processing in cyclone.

Centrifugal Pump used for mud mixing
By connecting with mixing hopper and manifold, the centrifugal pump can be used as a mixing pump for adding mud material into the drilling mud. The pump also has shearing function for some polymers.

Centrifugal Pump used at trip tank
On rig site, when replacing the drilling pipe, drilling mud need to be pumped down to the drilling well for supplement of the pressure decreasing. The centrifugal pump is an ideal equipment to do this job.

Centrifugal Pump used as supercharge pump
The recycled drilling mud finally will be pumped back to rig top and going down to the drilling bit. Between the mud system tank and high pressure mud pump, the centrifugal pump could be used as a bridge for transferring the active drilling mud to mud pump.

All the spare parts of GN centrifugal pump are interchangeable with world famous brand pump, which makes the maintenance of the pump more convenient. To ensure a long working life, GN adopts hard ductile iron alloy as the material of pump casing and impeller. For more information on GN centrifugal pump, please no hesitate to contact with GN.

This week, GN will ship out 9 sets drilling fluids shale shakers ordered by a Shandong client. Shale shaker is one the main products in GN production line. With more than 10 years’ experience in designing and manufacturing the shale shaker for drilling fluids recycling, GN has upgraded several versions of the shale shaker for better meeting clients’ requirement and the onsite performance.

The shale shaker is mainly used to remove the coarse solids in the drilling fluids recycling or other separation job. GN has 3 standard series of shale shaker as per application and capacity.

Drilling fluids shale shaker GNZS703F is with treating capacity of 120 cubic meters per hour, and it can be used in normal oil drilling solids control system and larger capacity trenchless drilling mud recycling system. This model is with 3 panelshaker screens and can be upgraded to GNZS706 double layer shale shaker with 6 panel screen for large capacity and both coarse and find solids separation.

GNZS594F is a shaker model with 4 panel screens for capacity of 140 cubic meters per hour. The screen matching this shaker is interchangeable with world famous brand. By changing the feeder to a hopper type, this model shale shaker could be used as a high G force drying shaker used in drilling waste cuttings management system.

GN also has small capacity mini shaker model GNZS752F with 2 panel screens, 45 cubic meters per hour. This model could be used in small HDD mud system, piling project and diamond core drilling project. It is worthy to mention that this model can also be upgraded to GNZS753F with 2 layers screen.

All GN drilling fluids shale shaker is provided with installed composite frame shaker screen with much durable features and long working lifetime. Client can find almost all the popular replacement shaker screen in GN. Please click below link for more information on GN Screen Purchasing Reward Point policy to get a shale shaker with big discount.

Today, GN quality inspectors made the delivery inspection for one batch mud centrifugal pumps and other solids control equipment that would be shipped to a Russia client. These equipment ordered including 6 shale shaker, 2 mud cleaners, 6 centrifugal pumps, 2 centrifugal degasser and 4 decanter centrifuges for 2 rigs.

GN has more than ten years’ experience in making solids control equipment. Client can get proposal of both single equipment and complex solids control system from GN. Welcome call and ask for a quote.

Recently, GN finished the factory delivery inspection of one set 1000 GPM mud recycling system that will be used in India for big trenchless project. In end of April, GN just shipped out 3 sets 600 GPM mud system to an Asian client who has already had 3 sets mud recycling system from GN.

1000 GPM Mud Recycling System is consisting with following equipment

1. Two units of GN double deck shale shaker GNZS706F for primary solid removing. Double deck shaker is with large capacity due to two-layer screen design for both coarse solids and fine solids separation.
2. De-sander unit GNZS703F-2S is with two sets 10 inch cyclone for sand removing. De-silter unit GNZS703F-12N is with 12 sets 10 inch cyclone for silt removing. The under flow shaker is with same dimension shaker screen for client’s easy shaker screen procurement or inventory.
3. Three sets 40 feet containers are used respectively as mud recycling tank, mud storage tank and mud mixing tank. Other equipment like centrifugal pump, agitator, and mixing hopper are installed on tank and shipped without disassembling them.

With nearly 10 years’ experience in design and manufacturing the trenchless mud recycling system, and sufficient feedback from clients’ onsite application. GN has improved GN compact mud system with stable performance and optimized design. All equipment in the mud recycling system are with advantages in increasing the working efficiency and improving the treating result.

GN is able to provide the mud recycling system used in trenchless project with compact design but self-contained. Other mud system design with plenty of mud tanks for large volume mud storage in oil drilling site, and some economic mud de-sanding unit in small drilling project like water well drilling and piling.

This week, GN is almost finished the fabrication of 8 units solids vacuum pump what would be used in a long distance mud transfer project in Beijing. Now GN’s engineer is the making the last step of delivery inspection and packing.
In client’s project, it is a long distance from the mud pit to the rig. This brought a problem to client how to transfer plenty of mud to where it would be used. The client didn’t get a good solution till they saw GN vacuum pump at the CIPPE show this March.

GN Solids Vacuum pump is a 100 percent pneumatic driving pump that could be used to transfer high solids content sludge like the oilfield drilling waste cuttings, normal drilling mud in recycling system, vessel remaining sludge etc. The other feature of this type pump is the capability to suck and discharge the sludge from and to faraway place.

The client totally order 8 this vacuum pump from GN, and each 4 of them would be installed together to get a large capacity. Besides the pumps, client also ordered 2 empty containers that would be especially used to pack and mount the pumps. Few people will get the idea to put the pump unit into the container. This installation will bring some benefits. All parts of the pump would be covered and protected. All the pumps are installed in the container neatly for convenient operation onsite. This package term is also good for transportation, client only need one time lifting, then 4 pumps can be loaded on the truck. The vacuum pump need air compressor to work, thus the container is provided with air buffer vessel. All suction and discharging pipe manifold are provided and connected, before running onsite, client only need to connect the quick connectors.
GN solid vacuum pump can be used in waste cuttings management system, solids control system, sludge pit cleaning project. For more information, please feel free to contact with GN.
