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.

Mud Agitator and Centrifugal Pumps for Overseas Workover Drilling Rig

One batch of mud agitator and centrifugal pumps are ready for delivery for overseas workover drilling rig.
The mud agitator is coupler connection type, the gearbox and explosion proof motor is connected by coupler. The features of the GN E version mud agitator:


1. Helical bevel type heavy duty gearbox for reliable operation, good performance and longer working life.
2. The tooth surface coincidence degree of the helical bevel gearbox is bigger, it reduces the load if each pair of gears and improve the bearing capacity of the gears.
3. The explosion proof motor is installed horizontally for easier installation and maintenance, also the client can install their own explosion proof motor if required.
4. Stirring intensity is high, the sweeping area is wide, it can improve the agitating performance of the drilling fluids
The centrifugal pump is the supporting equipment for oilfield industry, mining and construction industry, it can be applied to transfer corrosive drilling fluids, construction slurry and other mud. In the solids control system and mud circulation system, it can be used as trip pump, desander feeding pump, desilter feeding pump, mud pump charging pump, mixing pump and transfer pump.
Features of GN centrifugal pump including:


1. All the spare and wear parts are interchangeable with world famous brand centrifugal pump, the client can use their inventory parts for GN centrifugal pump.
2. The pump casing is made of wear resistant alloy ductile iron, which extent the working life of the pump casing, with better wear resistance.
3. The impeller is made of wear resistant alloy ductile iron for longer working life, and the open impeller design reduce the bearing capacity of the shaft and extent the bearing service life.
If you need mud agitator, centrifugal pump, mud gun, mud hopper,etc. solids control equipments, pls contact with GN solids control.

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.
