vacuum pump

Recently 1 set of oil sludge treatment plant is almost ready for shipment to Asia client, it is under testing in our facility before shipment. The treating capacity for oil sludge separation is 5 m3/h. We also have standard or customized designed oil sludge separation system with 1 m3/h and 15m3/h for option.


The general working process is as below:
GN sludge vacuum pump transfer the oil sludge from the waste pit/pond to the pre-mixing modular, the pre-mixing tank equipped with heating lines which can heat the oil sludge to increase the flowability of the oil sludge and increase the separation efficiency of the shale shaker, decanter centrifuge. By adding the chemicals, it will also increase the efficiency of the further process steps. 2 mud agitator and one submersible slurry pump are installed on the pre-mixing tank with electric control system.
Then the pre-treatment oil sludge is transferred to the shale shaker to separate the coarse solids by the submersible slurry pump, it also reduces the solids content of the oil sludge so that the centrifuge could separate the fine solids easily. The shaker screen is specially made with big opening to separate coarse solids to protect the decanter centrifuge.
The screw pump feed the oil sludge to the decanter centrifuge, the discharged fluids is flow to the 3 phase centrifuge to separate the oil and water. The clean water and pure oil is flow to the buffer tank , which will be pumped to the oil storage tank and water storage tank. The water can be used for the circulation again.
The 20ft container loading dewatering unit will be used when necessary with decanter centrifuge, the chemical jetting is to make the oil mixture easily separated by the decanter centrifuge.
If you need a customized solution for waste oil sludge treatment, pls contact with GN sales for more information.

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.

56 units of drilling fluids mud agitators and 3 units slurry vacuum pump shipped to China client this week.
The mud agitator is consist of electric motor and gearbox and skid, it is installed on the mud tank to prevent the solids from accumulation on the tank bottom. The mud gun length and mud agitator shaft length is customized according to mud tank inner depth. GN mud agitator have C version and D version, the C version mud agitator is that the electric motor and gearbox is connected by coupler , if the client need local standard motors or they want to install their own motors, they can buy the gearbox with coupler and skid, and install the motor locally to meet the special explosion proof standard. D version mud agitator is the lastest mud agitator, the gearbox and electric motor is connected directly, with compact design, it will save space on the mud tank, and easy for maintenance.
The slurry vacuum pump is the most popular drilling cuttings transfer pump since this year, with the advanced technology. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer. The pump can transfer material with high gravity and high density, solids content max. up to 80%.
GN solids control can offer various pumps, including submersible slurry pump, centrifugal pump, screw pump, vacuum pump for different applications. Vacuum pump is our new products, we already sold it to many jobsites in the world.
