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 order to help preventing the drilling cuttings from polluting the land and water, and also to match the clients’ requests to minimum the cost, GN has successfully designed and manufactured several solutions of waste management systems for safely and economically discharge the drilling cuttings, and those designs have won the acceptances and good feedbacks from the clients.


Per different conditions, GN has designed 2 optional standard solutions:

  1. GNDC40A. it combines the vertical cuttings dryer GNCD930 and high speed decanter centrifuge GNLW363CG, or GNLW363CG-VFD, it fits for both OBM and WBM drilling cuttings. It has a compact structure but there is no storage tank for receiving the clean drilling fluids from the centrifuge. Because this design is suitable for being used alongside the drilling rig, the liquid goes directly from the high positioned centrifuge to the solids control’s storage tank.
  2. GNCD40B is another standard solution for the complete drilling cuttings waste management systems. If the equipment is disassembled from the tanks, the whole system could be transported in a container and easily shipped by sea. Comparing with GNDC40A, this 40B system has a larger storage tank and always used for treating the drilling cuttings separately from the drilling rig jobsite.


If per your jobsite layout or requested functions, they are not so satisfying for you, you could choose GN waste management modules, including GNZS594HGE-LD drying shaker, GNCD930 vertical cuttings dryer and GNLW363CG-VFD decanter centrifuge, and several equipments for optional for transporting the drilling cuttings including the screw conveyor, the submersible slurry pump, the vacuum pump or the diagram pump. In this way, you can choose your own equipments and position them at any place for your project. During the procedure, you can easily choose to stop or start any of them.

In early this year, GN has delivered a slurry unit to a well know middle east company which has business and projects covering many sections of oil and gas industry, including the construction and pipeline laying projects, and also the refinery of oil.
In most persons’ mind, the best equipments and most advanced equipments are from USA or European companies. But GN Solids Control has changed their mind with good quality equipments and reliable service. This is the first time this company chooses a Chinese supplier, before that, they purchase only from USA, like the Vermeer rigs and Derrick shakers.
The first deal with GN is like a trial deal. The operation manager say, it is their first time to use a desanding plant, and it is also the first time they buy from China. If this mud system works well, the second order will come soon.
GN Solids Control didn’t fail in satisfying the clients, within the first 10 days of working on jobsite, the middle east client sent the second order, of the same desanding plant from GN. And this mud system for the second order, was delivered to the loading port last week and soon, within 30 days, it will arrive to the new owner.
