GN Company Supplied Automatic Tank Cleaning System for South American Market

Recently GN Company finished production of One Unit of Tank Cleaning System for client from South American.

GNTC-30C Automatic Tank Cleaning System is used for cleaning Mud Tank, Oil Tank, Chemical Tank, etc. Its working procedure is to transfer cleaning water to High Pressure Tank Cleaning Machine mounted on the tank, and Integrated Pump would pump waste water back into Tank Cleaning System for filtration & Separation. Then the clean water after treatment would go back to the system for reuse.

Tanking Cleaning System Detailed Procedure is as below,

High Pressure Centrifugal pump (8) pump clean water from Buffer tank (7) and supply to tank cleaning machine(2) to clean the mud tank.
Suction Pump (2) suck dirty wash water from mud tank through the strainer (1) which will filter the coarse solids.
The suction pump (2) will feed dirty water through the static mixer to inclined plate clarifier (5).
The chemical dosing system (3) will supply chemical/flocculants to the static mixer (4) to mix with the dirty water to enhance the separation in the IPC.
The inclined plate clarifier (5) will separate settable solids.
The clean water from IPC (5) will overflow to buffer tank (7).
The buffer tank level control system will control the pumps automatically.
Membrane Pump (6) will take the settable slurry from the IPC (5) to Skip.

Small Order But Big Amount Business-Centrifugal/Sand Pump Spare Parts

As Pump Users/Engineer know that the Pump actually are assembled by many different small parts, including Motor, Bearing, Seal, Spring, Shaft, Packing Set…… The end user may purchase the Pump by different channels, such as Shop, Distributor, Trading Company, or Shopping on line, and these parts are from different manufacturers or bands. Somehow it is always a big headache for the end users to find available spare parts for replacement.

GN Solids Control Company is professional pump manufacturer for 11 years, including Centrifugal Pump, Sludge Pump, Screw Pump and Submersible Pump.

Today we would like to offer the detailed information about our HOT SALE pump—Centrifugal Pump.

How to deal with the Water and Sludge after Flood?

One week ago, an Indian friend shared me some pictures and videos for the Flood in their country, and the terrible situation after Flood. The streets were full of sludge, and many parts of the city were still full or water.

It shall be a big headache for the local government to deal with the environment, besides the homeless people.

We, GN, a professional Chinese pump manufacturer for 11 years, we have two models of pump could be widely used to remove the sludge and water after flood.

The Centrifugal Pump and Sludge Vacuum Pump.

Today we would like to share detailed information about Sludge Vacuum Pump, the GN Hot Sale Pump!

VACUUM PUMP

Sludge Vacuum Pump

Waste vacuum pump, also named as solids transfer pump. With special structure design, it can be used at tough environmental for solids transfer, high working performance and less maintenance.

Waste vacuum pump, also named as solids transfer pump. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer. With special structure design, it can be used at tough environmental for solids transfer, high working performance and less maintenance. The pump can transfer material with high gravity and high density, solids content max. up to 80%.

GN High Speed Decanter Centrifuge Used for Waste Water Separation

As more and more GNLW series decanter centrifuges are using in oil and gas drilling and drilling waste management systems, GN Solids Control sometimes are regarded as a professional centrifuge manufacturer, and some clients are using GN centrifuge in other industries as sludge separation, waste water separation and other applications.

Comparing with drilling waste management systems, the separation of waste water need the centrifuge to work at a comparably lower differential speed, which is also the speed for conveying the solids phase in the bowl.
Why? Why not a high differential speed?
1. First of all, a high speed for conveying the material may mix the liquid and the solids, and the whole centrifuge would be working as a mud agitator, in this case, the centrifuge is not an efficient separation equipment.
2. Secondly, in order to treat the waste water, the end user need to add some chemical into the material, to change the size or the chemical composition of the waste water. In condition of a high differential speed, the useful chemicals may be discharged together with the liquid at the liquid outlet.
3. Thirdly, when there is chemicals in the material to be treated, and the centrifuge’s differential speed is high, there would be quite much of bubbles and foams. It would give negative affect on the separation result.

GNLW363CG-VFD is an idea choice for the waste water separation projects, because this is the highest standard decanter centrifuge internationally, GN uses best material for the decanter centrifuge bowl as SS2205 which is more strong and more anti-corrosive.
And for the control panel, GN has positive pressurized control panel for easily choose the suitable bowl speed and differential speed. When the aimed bowl speed and differential speed are entered into the PLC control panel, the program will calculate out a suitable back motor speed automatically.
