Classified by drive mode, Decanting Centrifuge has different models, like hydraulic drive, electric drive and also magnetic drive. Different drive model has different advantages and disadvantages. Hydraulic drive centrifuge can be started very smoothly, with less noise and less friction. But once some problems arise, it is very hard to maintenance. Electric drive is not that smooth when starting, but is easier for maintenance for trouble shooting, so that lead to less cost.

Some remarks:

FHD: Full Hydraulic Drive ; VFD: Variable Frequency Drive;  Magna: Magnetic Drive

Derrick DE-7200VFD Decanter Centrifuge is Variable Frequency Drive Centrifuge which is designed to achieve larger treating capacity and keep pace with the ever-changing needs of the oil and gas industry. New model centrifuge has been combined with durability and reliability in a product that is easy to operate and fully adjustable.

But with time goes by, not only Derrick can fabricate this big treating capacity centrifuge, GN Solids from China have already control the core technology and can fabricate the big bowl big capacity centrifuge, GNLW553VFD.

Hereunder, we compare these two brand centrifuge, US brand VS China brand. And let us know more about the difference and similarity.

Decanter Centrifuge is important both for solid control system and waste management system. A variable frequency drive centrifuge can offer different speed for different use. Lower speed is better for barite recovery during solid control; higher speed can be OK to separate cuttings during waste management operation.

Under current situations, well-known centrifuge brands are MI-Swaco, Derrick Equipment, Nov Brandt and a new star from China- GN Solids. The China brand GN reach the step of US brand with its core technology, excellent management and reliable after-sales service. Let’s compare one of US brand below with GN decanter centrifuge.

Drilling fluid is expensive in the oil drilling operation. The cost is even higher than solid control equipment. If you use solid control system to recycle valuable drilling chemicals, it will save a lot of money. Decanter centrifuge is designed for barite recovery and dewatering in global drilling projects where the best efficient fluids/solids separation is required. Hereunder, we introduce world popular US brand Derrick DE-1000 FHV and China brand GNLW363VFD.

Historically, Separation plants have been the bottleneck in many tunneling projects, resulting in lost time and money to the contractor. Before the start of the project, It is very important to plan ahead to have the properly sized and correct equipment in working place. Note: poor planning results in poor performance and money lost.

GN Solids can offer customized mud system matching with your TBM. Drilling mud treating capacity is from 200gpm to 1000gpm respectively. Please contact GN Solids to get proper solution for your tunneling project.

For world well known directional drill rig, there are Ditch Witch, American Augers, Vermeer. The three brands occupy most part of international market. For small drill, no need mud system. But for drill rig above 150gpm, a small mud recycling system can help you work more efficiency and environment friendly. For small mud system, GN Solids have 150gpm, 200gpm,250gpm, 300gpm for option. They can also customize as per the customer request.

Coalbed methane (CBM) reserves are a relatively untapped energy source with huge potential. It has become an important source of energy in all over the world, like Canada, United States, Australia, China, etc. The exploration of CBM is similar to geothermal well drilling. They mainly need rig, mud system, mud pump, and some other accessory equipment.

Decanter centrifuge is core equipment both for solid control system and waste management system. With constant improvement of the requirements from customers, many customers attach more importance on the bowl diameter and treating capacity. In China up to now, only GN can manufacture big bowl , big volume decanter centrifuge, with bowl diameter 22inch and treating capacity Max.500GPM.

Among ME countries, Iran market is a good market for oil drilling. Many equipment suppliers and drilling contractors have been working hard on the market for many years. Up to now, in the field of solid control equipment and service, the fact is that some U.S. brands control the most part of the market. And it is not easy for China brand to come, even with high quality and inexpensive equipment. We may talk about decanter centrifuge as one aspect. In Iran, the most popular model of decanter centrifuge is Swaco CD518HV and GNLW363VFD. They are both high speed centrifuge model.
