BIG BOWL CENTRIFUGE

Ever since the establishment of GN Solids Control seven years ago, Australia has been the market of GN Solids Control and most of their purchases have been mostly the solids control systems and mud recycling systems for the HDD or other drillings.

GN Recent News FYI: 

But now as the demand for environment protection all over the world is becoming more and more important, more and more drilling companies have paid an eye to the waste management solutions for further treating the drilling cuttings and the drilling liquid, in order to give the least damage to environment meanwhile reduce the drilling cost mostly, by deleting as much solids and well discharging them, and recycling as much as drilling liquid for future use.

Not long ago, an Australian company purchased 2 sets of GN Big bowl centrifuges, GNLW553-VFD, and now the centrifuges are well tested and ready for delivery.

What are the main specification of GNLW553-VFD Decanter Centrifuge?

1. bowl diameter of GNLW553-VFD decanter centrifuge is 22 inch, big bowl. By having this bowl diameter the max capacity designed for this centrifuge is 90 cbm/hour, equal to 400GPM.
2. a long ratio of length and diameter. This value is 3, so the length of the bowl is 71 inch. 3 is a perfect and practical length-diameter ratio, it gives an idea drying level of the solids discharge.
3. high speed up to 3000 RPM designed speed and typical speed up to 2500 RPM.
4. VFD control panal, GN uses positive pressurized control panel which could be used for high temperature condition and much safer than flame proof.
Besides above, the material and parts like bearings are of top brands and best quality, in order to ensure a reliable performance and a long service life.

In field of decanter centrifuge for oil and gas drilling, GN is always the leading brand.

For oil and gas drilling work in many jobsites, especially for deep oil and gas wells, there are many different material and chemicals or other additions used during work. Some cheap ones could be discharged or re-treated if they are harm for environment. While some expensive materials should be recovered for future re-use. Barite is one of them. So the barite recovery centrifuge is an important equipment.

GNLW452 Decanter centrifuge is an ideal choice for this application, in all the solids control systems GN made, most of them use this model GNLW452 for the barite recovery and it was proved efficient.

Main Specifications of GNLW452 Decanter Centrifuge:

Bowl diameter: 18 inch or 450mm

Bowl length: 43 inch or 1105mm

Effective capacity: 176 GPM

Max capacity: 250GPM

Max bowl speed: 1800RPM.

G Force: 815

Gear box torch: 57:1

GNLW452

GNLW452 Decanter Centriufge, big bowl large capacity

GNLW452 Decanter Centrifuge is designed to be a middle speed centrifuge, in order to separate the low gravity material like the barite recovery, in some jobsites, per customer feedback, GNLW452 is even having better performance than the US made and European brands.

What features does GNLW452 have?

  1. For this model, GN has improved it to the 3rd generation, with a lot of improvements, with better solids discharge and effectively avoids the blocking of material.
  2. Instead of spray welding on the impeller, GN use special ceramic tiles to ensure a easier future maintenance without re-adjusting the dynamic balancing and enables a longer service life.
  3. World famous brand bearings to get a stable performance and a longer service life.
  4. Patent solution for bearing protection during transportation which greatly helps to prevent damage to bearings.
  5. Big bowl, 18 inch bowl diameter to have a large capacity.

Other options for the GNLW452C decanter centrifuge.

The standard GNLW452C decanter centrifuge is a fixed speeded one, but for the same model, we also have VFD available. In some high standard HDD mud recycling units, end users prefer this centrifuge in VFD control panel after the hydrocyclones for further treatment.

Besides this model, GN Solids Control also have other sizes decanter centrifuges for you to choose, at least one will be suitable for your jobsite.

Last week GN Solids Control received an inquiry from an US customer on fully hydraulic drive mini centrifuge. This decanter centrifuge will be used for oil and water separation industry. In the fluid there are solids need to be removed before going to the next step treatment. The centrifuge will be used in Indonesia.

This customer asked for a small treating capacity decanter centrifuge with fully hydraulic drive.  GN Solids Control recommended their Mini decanter centrifuge GNLW223FHD to the customer. This GN mini decanter centrifuge has a treating capacity of 26 GPM.  The bowl length is 26 inch and the bowl diameter is 9 inch.  The max speed can reach to 4900 rpm with a typical G force of 1770G. The separation point is 2-5 microns. This mini centrifuge is formerly tested successfully in Canada.

Features of GNLW223FHD decanter centrifuge:

1. Reliable full hydraulic drive. The rotodiff is Sweden Made VISCOTHERM AG System

2. Variable speed. Typical bowl speed can be adjusted between 0-3800rpm

3. Bowl , Conveyor, Main body made from Stainless Steel:SS316L

4.Tungsten carbide tiles protection screw.

GN Solids Control has different capacity centrifuges available. 14 inch bowl and 22 inch big bowl are our most popular model. We have these models stocked in our Houston office and will be showed at OTC from May 5-8. Welcome to visit us and check them out.
