centrifugal pump

GN solids control showed our equipments at Petrotech 2019 in India from Feb. 10th to Feb. 12th. The equipments we showed at the oil show in India including:


1) Sludge vacuum pump: it can be used to transfer drilling cuttings, powder cement, waste sludge, oil sludge, drilling fluids, industry waste water, mining tailings, dredging slurry, sand, even for animal waste, etc. Especially for high viscosity sticky oil sludge from refinery crude oil tank bottom, the vacuum pump is an ideal equipments to transfer the oil sludge, but the flow rate will be different with the normal flow rate. Depends on the different conditions oil sludge, we will choose the proper model for our clients according to the question list they filled.


As a 100% air operation pump, the vacuum pump do not need any electricity to operation, this is pretty convenient in some jobsites when electricity is limited, the user can use the air compressor in the jobsite to provide air for the vacuum pump, they can choose automatic operation or manually operation for their requirement.
2) Centrifugal pump: the complete centrifugal pump is consist of pump head, coupler for motor end, coupler for pump end, electric motor, control panel, skid and other accessories. The pump head is the most important components for the centrifugal pump, our pump head and all the parts are interchangeable with world famous brand centrifugal pump.
3) Shale shaker: the 2 panel shale shaker is the smallest model we have now, we have 2 panel, 3 panel and 4 panel single deck shale shaker for option, also we have dual deck shale shaker for special purpose.

Recently GN Separation & Conveying Equipment Company release new website, http://www.gnseparation.com/ , welcome to check our equipments information and industry news from our website. For the solids control equipments and drilling waste management equipments and oil sludge separation system information, pls check our website www.gnsolidscontrol.com, also you can check the working video and project news from this website.


Our major separation and conveying equipments including:
1) Decanter centrifuge for waste water treatment, mining & industrial sludge/ tailings treatment, chemical treatment. The bowl size available is 9 inch bowl, 14 inch bowl, 18 inch bowl, 22 inch bowl, 30 inch bowl with different treating capacity, and each bowl size have ratio available for 3 or 4 or 4.2. By the different requirement for the discharged solids moisture and discharged water clearance, different ratio ( bowl length / bow diameter) will be choosed, and the bowl angle is customized for different material.
2) Conveying Equipment: Screw Conveyor, Bucket Elevator for bulk material handling.


3) Transfer pump: Centrifugal pump, solids vacuum pump, screw pumps. The vacuum pump is widely used to transfer the cement, animal waste, oil sludge, drilling cuttings, drilling fluids, oil contaminated soils and other materials. It is 100% air operation pump without electricity power supply, it is ideal equipment to work in the electricity limit area. The air compressor is required to provide air supply for the vacuum pump operation. Centrifugal pump is interchangeable with world famous brand centrifugal pump installation and parts, it can be used as mixing pump, feeding pump of desander, desilter, trip pump, super charging pump, transfer pump of oil sludge. Screw pump is normally as feeding pump of decanter centrifuge and flushing pump of vertical cuttings dryer.

This week GN solids control shipped one batch of mud transfer pumps and mud agitators to Asia client. The centrifugal pumps are 100% interchangeable with world famous brand centrifugal pump, we can provide bare pump head and all the parts and the whole centrifugal pump with motor, skid, coupler, and control panel.


Features of GN centrifugal pump:
1. The impeller and pump casing is made of hard ductile iron alloy, which is abrasion resistant material and can longer the working life of the centrifugal pump. Different with the other competitors grey steel material, it is easily break.


2. The bearing is top brand bearing for reliable operation, the client do not need to repair the pump time and time and delay their operation.
3. The mechanical seal is also an important wear parts for the centrifugal pump, for better sealing and zero leakage and longer working life.
4. The mounting skid of the centrifugal pump is made from casting instead of welding to provide the reliable operation and less vibration for longer working life.


Mud agitator is one of the mixer equipment to be installed on top of the mud tank, together with tank bottom mud gun for better agitating and mixing of the drilling fluids in the mud tank, to prevent the drilling fluids to be accumulated in the tank bottom. The direct connection mud agitator design is with compact size, convenient operation, maintenance and customized agitator shaft length and impeller size for better performance.

10 units of shale shakers are shipped to India drilling company this week, they also produced one set of solids control shale shaker tank ready for shipment, including 3 units of same model shale shaker, 1 unit of mud cleaner, 1 unit of vacuum degasser, 1 unit of mud gas separator, 2 units of centrifugal pumps, and necessary mud agitators, mud gun, and 1 unit of mud tank.


GNZS703F-HB shale shaker is one of the best sold model shale shaker, with 3 panel composite material frame shaker screens, we produce OEM shaker screens in GN own shaker screens workshop. Except for the OEM shaker screens, we also produce durable composite material shaker screens for world famous brand shale shaker, like Derrick FLC 500 series, FLC 2000 series, hyperpool, D600, etc, Brandt King Cobra / Venom, VSM300, MI-SWACO Mongoose PT,MD 2/3, FSI, etc. Compared with the steel frame shaker screens, GN made composite material shaker screens with 20% larger effective screen area, the working life is much longer, the storage period is up to 5 years.


The mud cleaner is the combination of desander cone, desilter cone, underflow shale shaker, the treating capacity is different by using different quantity desander cone and desilter cone. GNZJ703F-1S8N with 500gpm capacity with 1ea desander cone and 8ea desilter cone. GNZJ703F-2S12N with 1000gpm treating capacity with 2ea desander cone and 12ea desilter cone. GNZJ703F-3S16N with 1500 gpm treating capacity. The feeding pump for mud cleaner is GN made centrifugal pump , the parts and installation dimension is 100% interchangeable with world famous brand pump.

This week GN solids control shipped one unit of HDD mud recycling system and dewatering unit to Sinopec project. HDD is one of our major applications, GN equipments 4 major applications including oil & gas industry solids control system and drilling waste management system and oil sludge separation system, HDD & CBM industry mud recycling system, Piling & TBM desander unit, Industry waste water treatment.


The technical configuration is as below:
1) 3 phase cleaning mud recycling system mud tank, with containerized frame for convenient transportation, the user can put the mud tank and the frame with equipments on the trailer and move to another site from one site.
2) 1 unit of GNZS703F shale shaker as the first phase cleaning equipment, equipped with 3pcs of durable composite material shaker screens with customized API mesh screen. We produce OEM composite material shaker screens from API 20 to API 325 as per client’s requirement.


3) 1 unit of GNZJ703F-1S8N mud cleaner, with under flow shaker, desander cone and desilter cone combination unit. Equipped with 2 units of centrifugal pumps as feeding pump of desilter cone and desander cone.
When the drilling fluids temperature is over 70 degree, we will use special material hydrocyclones for longer working life.
4) Dewatering system with same dimension mud tank
5) Decanter centrifuge GNLW363C-VFD is the 4th stage cleaning to separate fine solids smaller than 15 microns. After several years working, more and more fine solids are accumulated in the tank bottom, these fine solids can not be separated by the desilter cone, then high speed decanter centrifuge is required to clean the drilling fluids, otherwise it can not be reused for drilling again.
