GN Drilling Mud Decanter Centrifuge and Centrifugal Pumps for Offshore Drilling Company

Recently GN drilling mud decanter centrifuge and centrifugal pumps are shipping to offshore drilling company.


The drilling mud decanter centrifuge is equipped with offshore lifting skid, compared with the onshore drilling mud decanter centrifuge, the skid for offshore drilling is special designed for safety and convenient lifting for offshore purpose, but without DNV 2.7-1 lifting certificate. When DNV 2.7-1 lifting certificate for the lifting pad is required, the skid should be designed specially. The stainless steel cabinet positive pressurized VFD control panel is separately on the ground, with main motor, back drive motor and pump motor 3 VFD, which is from ABB, YASKAWA, etc. famous brand, the other like PLC and touch screen and other electrical conponents from Siemens and other famous brands. The decanter centrifuge bowl and the screw core shaft are made of duplex stainless steel SS2304 by centrifugal casting, which is superior to the performance of SS304 and SS316.The solids outlet and fluids distribution port is protected by replaceable hard alloy sleeve. The wear resistant and anti-skid bars welded inside the bowl can effectively reduce the wear of the bowl under operation. The screw main material is also duplex stainless steel 2304. The screw blade is protected by tungsten carbide tiles, which is replaceable hard alloy plate.
The centrifugal pump all the parts are interchangeable with international brand pump, so the client can source the parts easily. The pump casing made from hard ductile iron alloy, which increased abrasion resistant performance. The pump skid is special designed for client’s particular requirement.


Except for drilling mud decanter centrifuge and centrifugal pump, we also produce linear motion shale shaker, mud cleaner, desander, desilter, vacuum degasser, mud agitator, mud tank system, etc. solids control equipments for the onshore and offshore drilling. For more information, pls contact with GN solids control.

Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.
