Mud agitator manufacturer in China

As one of the mud agitator manufacturer in China, GN solids control can produce both direct connection and coupler connection mud agitator according to client’s requirement. The mud agitator model will be selected according to tank design and tank dimensions. The most popular mud agitator is horizontal type with helical bevel gearbox, the motor and gearbox is direct connection.


To select the mud agitator horsepower and impeller size, we will collect information as below: tank shape is rectangle tank or vertical cylinder tank, the tank dimension, maximum mud weight and desired turnover ratio. The TOR value should not less than 40 second and should not greater than 85 seconds. According to the client’s requirement, we can supply different explosion proof standard, such as CNEX, IEC EX, ATEX or UL.


When install the mud agitator on the mud tank, the agitator should be lifted horizontally, and place it on the right position, put the agitator shaft on a strict vertical line, then weld 4ea pad on the tank and tighten the base fixing bolts. Welding the stabilizer on tank bottom, and put the shaft with impeller into stabilizer. Adjust the position of the stabilizer to make the shaft vertical, and ensure the normal rotation of the shaft, ensure the stabilizer will not affect the rotation of the shaft.
The mud agitator main components including gearbox, motor, gearbox mounting plate, shaft, shaft stabilizer, impeller, if it is coupler connection mud agitator, also with coupler. The electric control panel will be installed besides the mud agitator.
Except for mud agitator, GN solids control also produce mud gun, mixing hopper, centrifugal pump, shale shaker, mud cleaner, desander, desilter, vacuum degasser, decanter centrifuge, screw pump, submersible slurry pump, mud tank, mud gas separator, vertical cuttings dryer, screw conveyor, electric control panel, high G drying shaker, etc.

How to operate a sludge vacuum pump?

As sludge vacuum pump manufacturer in China, GN solids control produce 100% air operated vacuum pump with different treating capacity, including GNSP-10B, GNSP-20B, GNSP-40B.
How to operate the sludge vacuum pump with 40m3/h flow?


Firstly connect the air supply, normally air compressor which meets the pressure requirement, and manual mode or automatic mode can be selected as client’s requirement.
When automatic mode is selected, set the “automatic and manual switching valve” to the “zero position”, turn on the air supply, set the switching valve to the “manual state”, and set the “loading and unloading switching valve” to the “unloading state” to confirm the emptying of the material in the tank; Time 2 minutes;


Restore the “automatic and manual switching valve” to “zero position “, switch the “automatic and manual switching valve” to the “automatic state”, and the equipment can operate in automatic mode. The equipment will automatically suction and unloading according to the set loading and unloading time; (according to our experience, setting values for loading and unloading are 10s, which can be adjusted by users according to on-site conditions);
If manual mode is selected, set the “automatic and manual switching valve” to “manual state” and the “loading and unloading switching valve” to “unloading”;
Restore the “loading and unloading switching valve” to “zero position”; Place the suction port into the material to be sucked in
Turn the “Load and Unload Switching Valve” to “Load”, and the pump starts to suck materials when the tank is full; Turn the “Load and Unload Switching Valve” to “Unload”, and the pump starts to discharge slurry.
The automatic mode and manual mode can be only selected for GNSP-40B vacuum pump, the smaller size vacuum pump with only automatic mode. The vacuum pump can be used to transfer drilling waste from solids control equipments, drilling fluids, animal waste, sand, powder material, oil sludge, etc. material.

The exhibition information is as below:
Exhibition name: 2023 NEFTEGAZ Russia Oil Exhibition
Exhibition time: April 23th to 27th, 2023
Exhibition location: Expocentre Fairgrounds, Moscow, Russia
This year we showed GN decanter centrifuge, vertical cuttings dryer and shale shaker screens.


GN 14inch bowl decanter centrifuge is one of the most popular model decanter centrifuges for oil and gas drilling fluids treatment and drilling waste treatment system, it can be also used as dewatering centrifuge with chemical dosing unit. We can produce high speed decanter centrifuge, VFD decanter centrifuge and Fully Hydraulic Drive decanter centrifuge for different application, also we can provide different explosion proof standard for your requirement, CNEX, ATEX or IEC EX.


The vertical cuttings dryer is widely used to treat OBM, SOBM drilling waste, it can reduce the oil from the cuttings effectively. Even under minus 40C degree in the winter, GN vertical cuttings dryer is also able to work well inside special decorated container to keep it warm.
If you need a containerized drilling waste management system solution to our client, if you need more information, pls contact GN Solids control.
