GN Solids Control manufactures different types of feeding pumps, such as centrifugal pump, submersible pump, screw pump, vacuum pump etc. All GN made pumps can be used to transfer solids and liquid.
GN Solids Control made centrifugal pumps are largely used to transfer solids and liquid, every year GN manufactures over 1000 centrifugal pumps that are using in more than 70 countries and regions. GN made centrifugal pumps are totally interchangeable with Mission Magnum pumps, many USA pump manufacturers are using GN pump parts to repair the OEM magnum pumps.
GN centrifugal pumps can be used as feeding pumps for desander or desilter. Drilling mud can be also used to transfer by centrifugal pumps between different mud tanks. As GN centrifugal pump is a wearable parts, GN Solids Control engineers use mechanical seal made with tungsten carbide. Besides, a packing seal is also used. GN centrifugal pump’s impeller is designed to use pretty low axial trust loads, this particular design is convenient for installation, maintenance and repair.
Besides the above mentioned advantages, here are more factors when you choose a good centrifugal pump:
1.GN centrifugal pump is using concentric design to minimize abrasive wear and lower the turbulence. In order to have longer using life, GN centrifugal pumps are using strong concentric and thick casing.
2.GN centrifugal pump casing is made from hard ductil iron alloy. This material can upgrade the abrasion-proof capability.
3.GN centrifugal pump is designed to have a wide open-vane impeller which helps to low the axial thrust, so bearing life can be extended.
4.In case of the improper motor hook-up, GN used anti-loosening impeller lock bolt.
5.Mechanical seal is high quality brand no-adjustment type, it provides long using life and zero leakage. Shaft sleeve is replaceable.
6.GN Solids only used op brands bearings.
7.By using casting method to manufacture the centrifugal pump skid, GN Soilds Control makes sure te centrifugal pump has less vibration and reliable operation.

Welcome to visit GN Houston office to check GN shale shakers and centrifuges.

GN Solids Control is a leading decanter centrifuge manufacturer in China. Now GN Solids Control centrifuge covers 9 inch bowl centrifuge, 14inch bowl centrifuge, 18inch bowl centrifuge, 22inch bowl centrifuge and 30inch bowl centrifuge. GN decanter centrifuges are widely using in various solids and liquid separation area, such as drilling mud separation, dredging water treating, chemical separation, oil sludge separation and industrial water treating etc.
GN Solids Control centrifuge had variable speed and fix speed control model, based on the working environment, GN Solids Control centrifuges have Zone I or Zone II explosion-proof centrifuge.
As we all know, GN Solids America LLC is the brand company of GN Solids Control. Now GN Solids America has some decanter centrifuges stocking in Houston warehouse. Customer can pick up centrifuge from GN Houston warehouse directly without waiting for the long time shipping.
Today we would like to give everyone a short introduction of GN 9 inch bowl centrifuge. GN Centrifuge is mainly including the following components: rotating bowl, screw propeller, supporting frame and 2 driven motors.
GN centrifuge rotating bowl is made by stainless steel, as whole piece is made by centrifugal casting without welding. Inside the rotating bowl, screw propeller is protected by tungsten carbide tiles based on the using conditions.


Due to the portable character of GN 9 inch bowl centrifuge, it’s largely used in remote area for diamond drilling or core drilling mud control so helicopter can move it can move it conveniently.
9 inch centrifuge is also called GN baby centrifuge, the treating flow rate is around 50GPM which is pretty popular in many labs for test scale usage. Last year, GN solids worked together with some USA laboratories and research centers, many scientists are using GN 9 inch bowl centrifuge to treat slurry and eliminate finer particles larger than 2 to 5 microns.

8.4# Centrifuge &Disc-centrifuge
Slurry in #1 centrifuge tank is pumped by #2 screw pump into #2 centrifuge: solids fall into cuttings box, liquid falls into #2 centrifuge tank and then feed into #1 disc-centrifuge by an inline pump to finish 3 phase separating: oil , water and solids. Dis-centrifuge needs water to discharge when working, a water tank is fixed one one side of #2 centrifuge tank. Meanwhile, on the other side of the centrifuge tank, an inline pump is used to feed slurry.


9.5# Disc-centrifuge & Surge Tank
1# disc-centrifuge treated oil goes into #5 unit’s #1 oil surge tank, water goes into #1 water surge tank. Slurry in #2 oil surge tank of #5 unit is pumped into #2 disc-centrifuge by inline pump: oil goes into #1 oil surge tank, water goes into #1 water tank and solids discharged to the outside. When the oil in #1 oil surge tank reaches to a certain level, liquid level alarm monitors the level and gives signal so the inline pump can transfer slurry into appointed position. At the same time, #1 water surge tank slurry is transferred to #6 gravity oil/water separator by an inline pump.
10.6#Gravity Oil/Water Separator, Water tank
Inline pump transfers slurry into #6 Gravity Oil/Water Separator: oil goes to #6 unit’s #3 oil surge tank and water goes to #6 unit’s #2 water surge tank. Slurry in #2 water tank is transferred by an inline pump to micro bubble treating unit for further treatment. Inline pump and pipes are fixed near #2 water surge tank, in case water is not clean enough, it can be pumped into #5 unit’s #2 oil surge tank and to be further treated by #2 disc-centrifuge.
11. Oil tank
Inline pump transfers the slurry into #7’s micro bubble treating unit, after treated: clean water is send into #7’s water tank and provide recycled water; oil goes to #6 unit’s #3 oil surge tank which is monitored by liquid level alarm. Inline pump is used to transfer the slurry into appointed area. With the whole system runs, waste sludge can be recycled and also solve the environment pollution issue.
12.Chemical Dosing unit
All outside pipes; all inlets are controlled by valves on and off; can add chemicals/water in different position.

GN Oil Sludge System Working Process
Oil sludge in the V-Tank is separated by gravity into different layers after mixed by the bottom screw conveyor, the top floating oil (large portion) is transferred by a diaphragm pump into #2 oil surge tank, and the left small portion oil is feed into afterwards shaker shaker by centrifugal pump to finish the first phase separating.
GN Shale shaker can separate out most of those large solids, liquid is feed into #1 GN Decanter Centrifuge by screw pump where the second phase separating is achieved.


Solids treated by GN Centrifuge fall into the bottom tank of #1 centrifuge and diluted a second time. And liquid goes to #4 Centrifuge and Disc-Centrifuge Treating Unit’s Tank. Slurry in #1 centrifuge tank is transferred by #2 screw pump and feed into #2 Centrifuge to further separate: solids are collected by a GN cuttings box; liquid is fall into #2 Centrifuge tank, a inline pump is used to feed it into #1 Disc-Centrifuge where solids, oil and water is treated at the first time: oil goes to #5 unit’s #1 oil surge tank; water goes to #5 unit’s #1 water surge tank; solids discharge to the outside.
Slurry in #2 oil surge tank of #5 unit is feed into #2 Disc-Centrifuge by inline pump: oil goes to 1#oil surge tank; water goes to 1#water surge tank; solids discharge to the outside.
Slurry in 1#water surge tank of #2 unit is feed into #6 GN gravity oil/water separator by inline pump: oil goes to #6 unit’s #3 oil surge tank, water goes to 6# unit’s #2 water surge tank and then feed by another inline pump to #7 micro bubble treating unit: clean water goes to #7 unit’s water tank, provide recycled clean water for this whole system; oil goes to 3#oil surge tank of #6 unit. A oil pump is fixed on #3 oil surge tank, in case the oil is not clean enough, oil pump can transfer back to #2 oil surge tank, and then treated in 2#GN disc-centrifuge again until reach the final treating demands.
