shear pump

In order to treat the drilling cuttings, operators need to check out way to transfer the drilling cuttings to the treatment gear like high G dry skin shale shaker and vertical H cuttings dryer. The most popular opportunity for transfer drilling cuttings is a screw conveyors (Auger Conveyor), and the drilling cuttings send pump.

Part 1) Mess Conveyor for Drilling cuttings transfer
Screw conveyor can also be called Auger Conveyor, it truly is one of the most popular equipment to get transfer drilling cuttings. Advantages for the Auger conveyor will be the simple design, and easy operations, as well as a long length with regard to picking up the cuttings dismissed from the shale shakers or even mud cleaners on the drilling rig mud tanks. Often the disadvantages are that, it can be hard to layout for move from one equipment to the other, for the long distance. Since the conveyor cannot lay at qualification over 45 degree. Which is not good to transfer drilling cuttings with high moisture.
Component 2) Vacuum Pump or even  shear Pump for drilling cuttings transfer.
The vacuum cleaner pump or solids pump are used to transfer drilling cuttings. The big advantages are long-distance transfer with easy configuration, and it can be use to get transfer high moisture drilling cuttings. The vacuum pump or solids pump are generally driven by air, making it safe to operate in threats areas to be explosion explanation. The disadvantage are the power usage for creating air, and never suitable to pick up drilling cuttings from different equipment much like the shale shakers, mud cleaners and decanter centrifuge  on the mud tank.

So most of the cases, workers will combine the drilling cuttings screw conveyor plus the solids pump together to help transfer drilling cuttings for the treatment equipment.

GN Solids Control is able to provide you the actual screw conveyor and drilling cuttings transfer pump for any drilling waste management operations. Furthermore high G drying shaker and vertical cuttings electric drying machine are available from GN manufacturing in stock.

Last week, after months of hard work of all GN staff, 70 containers of solids control equipments from GN Solids Control sailed to Middle East. This is a land mark of not only GN’s company memorandum, but also a breakthrough of China branded solids control equipments and drilling waste management equipment. This order is working for oil service in middle east and work in tough conditions of temperature above 55 degrees centigrade.


Those equipments are of high quality material and per clients’ requests, they are of ATEX Zone 1 standard and with DNV lifting.

GN VFD controlled decanter centrifuges are always popular among the clients and countries in middle east and other high temperature conditions.

For the centrifuge main body, the high configuration GNLW series decanter centrifuges share the same features like:

  1. best bowl material SS2205 by centrifugal casting and such is the highest standard material for oil and gas decanter centrifuges. Many European and USA brands use this kind of material for bowl material.
  2. SKF bearings for stable performance and longer service life. And during transportation, GN has special and gentle solutions for protecting the bearings from being damaged on the rough road.
  3. tungsten carbide tiles for impeller protection and special ceramic material for solids discharge ports.

And many other features are applied.


About the VFD control panel, GN has both flame proof VFD control panel and positive pressurized VFD control panel with PLC smart touching screen. The positive pressurized control panel has the self cooling system, and it is more suitable than the flame proof ones in high temperature condition. All the electric components are of international famous brands like Siemens, Schneider and ABB. For this order, because they are of ATEX Ex, some brands and standards are even higher than usual.

To maintain the good relationship with some
VIP clients, GN Solids Control have plan to visit some big clients in different
regions. Our target is to conclude on the past projects, do after sales
service, offer free solids control items if necessary, and also talk more new project
coming in near future. This year, we have visiting plan to VIP clients in Iran,
Kuwait, UAE, Egypt, Nigeria, Russia, USA, Brazil, Australia, Korea, Argentina
etc. The VIP clients will support 80% sales amount of GN
. We cherish the long term relationship with the VIP clients,
and will improve every year to give better product and service.

GN Solids Control can develop so fast, one
is depending on the high quality equipment and good price. The other is
depending on the fast response after sales service. Our product have been
exported to over 60 countries. The sale amount each year can reach to about
20million dollars. The mainly equipment including:

1) Large quantity of decanter

Every year we export over 250 sets
centrifuge with feeding pumps. About 150 sets centrifuge for overseas market
and about 100 sets centrifuge for domestic market. Most popular model
centrifuge is GNLW363CG or GNLW363CG-VFD. GNLW363CG is GN fixed speed
centrifuge, with 3200rpm /2700rpm / 2200rpm speed. GNLW363CG-VFD is GN variable
speed centrifuge, with stepless adjustable speed from o to 3200rpm

2) Vertical cuttings dryer, not large

The needs of vertical cuttings dryer is not
that higher as decanter centrifuge. We may export about 20 sets vertical
cuttings dryer for drilling waste management.
The drilling waste management conception is also just aroused in past one to
two years. GN Solids Control vertical cuttings dryer can work similar as CSI
dryer after we test the dryer in drilling site

3) large quantity of pumps

We export large quantity of centrifugal
pumps, shear pumps,
submersible slurry pumps to overseas solids control drilling site and HDD
drilling companies.

If you need any solids control equipment,
pls contact us freely.

Centrifuges are greatly used in solids
control and drilling waste management systems in oil and
gas drilling industry, because it could separate out directly or together with
chemicals the fine and extra fine solid particles from the liquid at a high
rotating speed of the bowl. In a solids control system, it is always used after
the desilter and in waste management systems for drilling cuttings, it is used
after the high G dryer shaker or vertical cuttings dryer. When using together
with chemicals like dewatering, it is used after the dewatering unit.

Normally, what equipment is used to feed
the decanter
? Although in theory, the centrifugal pump could be used to feed
the decanter centrifuges just as the centrifugal pumps are served for the desander and desilter,
the centrifugal pump is not an ideal solution. Mostly practical options are submersible
slurry pump and screw pump.

1. submersible slurry pump: just as its
name, the submersible slurry pump has some part of the body underneath the
liquid, and it is vertically installed on the tank for feeding the decanter
centrifuge. In most cases, it is used for fixed speed decanter centrifuge. comparing
with a screw pump, it occupies less space for install and the price of
submersible slurry pump is lower than a screw pump, because the material and
producing technology is less complicated than screw pumps.

2. screw pump, also called mono pump in
practical uses, the most important parts of the screw pump are stator and
rotator, by rotating of the rotator, the transported media is conveyed evenly
and at a stable speed to the decanter centrifuge. Frankly speaking, this is
more suitable as the feeding pump of decanter centrifuges. GN always match its
decanter centrifuge with Netsch pump, which is a German brand, and the liquid
touching parts are all made of SS316L.

GN keeps research and develop the best
technology to manufacture top quality equipment ,such as Mud Gas Separator,
mud agitator, Vacuum
and other solids control equipment for our clients,

we only have big quantity of centrifuges, vertical cuttings dryer working in
North Africa, but now we also have many general solids control equipment
working there, eg. Centrifugal pumps, shaker screens etc.

GN brand decanter
for Africa market

brand decanter centrifuge is replacement centrifuge for Swaco centrifuge, or
derrick centrifuge, or NOV brandt centrifuges. They have similar working
principle, similar design, similar production material and also similar working
performance. That is why we call our centrifuge as replacement centrifuge for
USA brand centrifuges. In the past years, market share of GN centrifuge is
going up in fast speed. And the year production of GN centrifuge is also
doubled to meet the market demand.
