GN Solids Control Equipment and Vacuum Pumps for MENA client

One batch of vertical cuttings dryer, decanter centrifuge and vacuum pumps are ready for delivery for NEMA client.


The MENA region, encompassing key energy players such as Saudi Arabia, UAE, Kuwait, Egypt, and Algeria, requires equipment that can withstand extreme ambient temperatures and abrasive desert conditions. GN has confirmed that this specific batch has undergone rigorous factory acceptance testing (FAT) with an emphasis on:
Corrosion resistance for high-salinity formations.
High-temperature tolerance for hydraulic and lubrication systems.
The integrated system is designed to provide a closed-loop, zero-discharge solution for drilling fluid recovery and cuttings treatment. Here is a breakdown of the key components being delivered:
1. GN vertical cuttings dryer
Utilizing high-G force, this unit is engineered to recover valuable base oil or synthetic drilling fluids from OBM cuttings. By reducing the oil on cuttings content to less than 5% (by weight), the dryer not only saves significant fluid costs but also minimizes the environmental footprint of drilling operations—a critical factor for operators working in the sensitive desert and offshore environments of North Africa and the Middle East.


2. High speed decanter centrifuge
GN solids control is an OEM manufacturer of drilling fluids and drilling waste decanter centrifuge, we can produce high speed decanter centrifuge, middle speed decanter centrifuge, VFD decanter centrifuge, FHD decanter centrifuge. We can produce different bowl size decanter centrifuge, 9 inch, 14 inch, 18 inch, 22 inch, 30 inch. The discharged fluids from vertical cuttings dryer will be storage in catching tank, then the decanter centrifuge feed pump suck the fluids to decanter centrifuge for further treatment.


3. Vacuum pump
It is a 100% air operated vacuum pump for liquid ,slurry, and solids transfer. The pump can transfer material with high gravity and high density, with dry solids material or slurry with solids content max. up to 80%.

Drilling Mud Centrifugal Pump and Shear Pump for Europe Client

One batch of drilling mud centrifugal pump and shear pump are ready for delivery to Europe client.


Common Applications of centrifugal pumps on a Drilling Rig:

1.Feeding Solids Control Equipments: it works as feeding pump of desander cone and desilter cone
2.Mud Mixing and Agitation: Transferring drilling mud from a storage tank to a mixing hopper to add new bentonite or chemicals, or circulating mud in a pit to prevent settling.
3.Supercharging: Acting as a “charge pump” for the main triplex mud pumps. It provides a positive pressure at the suction of the main pump, preventing cavitation (a major cause of damage) and improving the main pump’s efficiency, especially when pumping dense muds.
4.Transfer and Loading: Moving mud from one tank to another or loading/unloading mud from supply boats or trucks.
Key Operational Considerations of the centrifugal pump:
• Proper Priming: The pump must always be flooded (full of liquid) before start-up. Running it dry will destroy the mechanical seal almost instantly.
• Wear Monitoring: Operators must regularly monitor the pump’s discharge pressure. A drop in pressure indicates that the impeller and/or volute liner are wearing down and need replacement.
• Cavitation Prevention: A “gurgling” sound and erratic pressure indicate cavitation, which is caused by a restricted suction (e.g., a clogged strainer or closed valve). This must be corrected immediately.


The features of GN shear pump:
1. It significantly enhance the hydration of moving soil particles
2. The shearing pump can provide shear efficiency accelerating the dilution and hydration of polymers.
3. It can make polymer shear dilution and hydration as soon as possible.
4. It can provide high discharge and head of delivery, which can meet the requirement of preparing and treatment of the drilling mud.
