A complete separation system is not only about the equipment used for separation, but also includes the equipment used for transferring material into the separation machines. A suitable and stable transferring pump ensures the efficiency of the equipment it feeds for and even greatly affects the whole system’s running.

GN Solids Control is professional in providing separation solutions, and all necessary pumps, too.
Like for the shale shakers, if the material to be treated is from the pit or pond, GN has submersible slurry pump or vacuum pumps, for the desander or desilter, GN has full series of centrifugal pumps and etc:

1. Centrifugal pumps: centrifugal pumps are the most frequently used mud transfer pumps in a solids control system, it is used for desander and desilter feeding, jet mud mixing, and trip tank filling. GNSB series sand pumps are totally interchangeable with Mission pumps even for small parts, and the raw material used for GN centrifugal pumps are most suitable for drilling mud transferring.

2. Vacuum Pump: it is also called the sludge pump or solids transfer pump, cause it can handling a material with high solids content and large particle size. It is fully mechanical driven by compressed air, and movable. It is widely used in waste management, oily sludge separation and construction.

3. Submersible slurry pump: it is used for pumping sludge from mud pit to a desander unit or other equipment, it is also an economic solution as centrifuge feeding.

4. Screw pump: GN cooperate with international famous pump brands for centrifuge feeding. Normally, in VFD control panels for decanter centrifuge, the 3rd VFD is used for the screw pump speed adjusting, and also for fixed peed screw pumps, GN also provide customized solutions by adding mechanical adjusting device.

5. For deep drilling works and some big capacity solids control system, GN has shearing pump for cutting the material with high viscosity.

If you need more information or some pumps in your project, welcome to contact GN freely.

In coming month, from December 12th to 14th, a new exhibition will be held in Thailand, focusing on the oil and gas industry, for both land rigs and offshores. The exhibitors cover the drilling industry, from the upstream to the downstream. During the exhibition, there are also professional conferences to be held.

About GN Solids Control

You may already know the three biggest oil and gas exhibitions in the world, one is the OTC in Houston, which is scheduled in each May in Houston, the technology center of the oil and gas industry, one is CIPPE which is held in Beijing, the capital of China, because China is becoming the biggest manufacturer and an up-rising technology R&D center, and also the ADIPEC, which is based in Abu Dhabi, one central city of Middle East, where the largest oil is located in. This exhibition in Thailand is hosted by the same company as ADIPEC.

Value of Asia: Asia has the largest population in the world. China and India are two of the biggest oil consumers and also the equipment manufacturers. Also the south Asian countries like Indonesia, Thailand, Malaysia and Singapore are also exploring oil reserves in adjacent seas. Some international big oil companies are locating their branch companies in those countries, and their business and contracts are covering regions as far as Africa.

Exhibition Name: Future Energy Asia
Exhibition Location: BITEC, BANGKOK, Thailand, from Dec 12th to 14th
GN booth: D40.

GN Will Bring Screen Samples to Exhibition, why?
As the leading solids control manufacturers in the world, GN Solids Control has the complete solids control and waste management equipment line as turn-key solutions, and GN has a separate workshop for shaker screens, equipped with an automatic screen producing line. All GN frame screens are made of composite frame, by robot cutting and welding and pre-tensioning and heat pressing by machines to minimize the faulty in production and to ensure the precision.

Just last week, GN Solids Control has finished a compact mud recycling unit, with full steps for separation for one of the largest oil giants in China. This system is to be transported to the jobsite by end of this year.

This system has 4 steps of separation, including:

1. GNZS703F. Shale shakers are always the first step for separation, because of GN shakers’ high G force and accurate API complied shaker screens, this shale shaker can efficiently separate out all particles larger than 100 microns, there in hence to help with prolonging the service life of the centrifugal pump after the shaker.

2. GNZJ703F-1S8N Mud Cleaner. Mud cleaner is a combined machine of desander and desilter, at a smaller foot print. It uses interchangeable shaker screens as GNZS703F, 2 centrifugal pumps are used to feed the desander and desilter respectively.

3. GNSP series Centrifugal pumps are also GN’s own products. For material choosing, GN used the high quality anti-weary material as pump body material by hard ductile iron alloy, and the main pump body is thicker than other manufacturers’. All GNSB series centrifugal pumps are using stainless steel mechanical seals.

4. Tank and skid for above mentioned equipment. Above mentioned equipment are located as 2 blocks. One block is a skid with lifting and anchoring corners just as a 20ft container, and the shale shaker and mud cleaner are located in the skid during transportation and operation. That design facilitates the operator for transportation or lifting the whole skid onto a tank, no to adjust each equipment or pipeline’s position.

5. A tank with compartments are designed to storage the mud from the shaker and from the desander/desilter. On below the tank, there are some slots for installing the centrifugal pumps. The whole outsize of the tank is also same as a 20ft container with container corners for lifting.

As the leading manufacturer of solids control and waste management equipment and also a professional separation solution provider, GN Solids Control has a products line covers the separation procedures and also the transferring procedures. GN Solids Control provides various pump for different applications including following:
1. Centrifugal pump, centrifugal pump is the most commonly used pumps in the oil and gas solids control industry, which is used for feeding the desander and desilter cones, for compensate the mud loss from the trip tank as trip pump, feed pump for the mud mixing unit for the mixing application and also plays as a role of charging pump. GN Solids Control produces the full range of centrifugal pumps from75kw to 7.5kw, equipped with mechanical seal, with high quality material for longer service life. All parts of GN series centrifugal pumps are interchangeable with Mission Magnum.

2. GN shear pump. Shear pump is not so commonly used as centrifugal pump. They are only used for shearing some special chemicals which are needed for large horsepower oil and gas drilling rigs.
3. Submersible Slurry pump. Submersible slurry pump’s applications in GN solids’ mud system and mud units are mainly those two: one is for centrifuge feeding in solids control systems like for the barite recovery and extra fine particle separation, or for the HDD mud recycling units, it is the second to none choice for transfer slurry from the mud pit to the mud system.
4. Vacuum pump. GN series vacuum pumps are the newest member among GN pumps. But it gained highest attention ever since its birth. Comparing with other pumps, the most obvious difference is that it has no motor. It is fully air driven and has less limitation for the solids size. In practice, it could handle material with particle size only a bit smaller than it’s pipeline diameter.

Although during the past 2 years, the waste management and environment protection proposals GN produced are occupying larger and larger share of all GN products, the traditional application GN Solids Control has been professional in has not lost it’s advantages. Recently, just when the oil and gas industry is picking up, GN’s international market is coming up again and a UAE client just purchased a 350GMP mud recycling system from GN Solids Control.
GNMS series mud recycling systems are one of the best seller products among all GN products, during those years, especially the 500 GPM mud recycling systems. In some jobsite, the 350 GPM mud system could serve as 500GPM mud recycling system, too.
This mud recycling system is combined by 2 phase separation equipment, plus a mixing unit. Depending on the limited space request on client’s jobsite, and also taking into consideration the transportation, the desander cones are not used in this system. For the first 2 level of separation, GN designed a double deck shaker, the lower shaker deck is served as shale shaker, with coarse meshes, .while the upper deck shaker is under the desilter cones, playing as the drying shaker for desilters.

On the other side of the tank, there is a mixing hopper, which is a common component of a mud recycling system for HDD projects. It is used to add and mix some necessary chemicals into the drilling mud.
Each year, GN Solids Control produces tens of mud recycling unit to the non-oil and gas industries, mostly for HDD, CBM, Water well drilling, TBM and Piling. All such mud systems could be grouped into 2:
1. Self-contained mud recycling systems with larger mud capacity and a mixing unit. Those systems, in application, are mostly used for HDD, CBM and etc. Normally, clients use a slurry pump to transfer mud from mud pit to this system and use mud pumps to suck out mud from the system.
2. Compact mud unit, without a mixing unit, mostly used for piling and TBM.
