GN Company Sludge Solids Vacuum Pump can be used to transfer sludge (high viscosity/density), Solids (powder, sand, soil), liquid (slurry from different industries).

Please find video about the Pump during work from linkage as follow.

Now GN Company Technical Team has already developed 3 models of this Pump, with different capacities, including 10, 20, 40m3/hour (if calculated based on Water, its capacity is 10, 20, 40tons/hour).

The Pump's suction depth is 8meters, while discharge vertically is 80meters.

The suction distance is 50meters, and discharge horizontally is 500/1000meters.

And there is one big advantage for our Pump is that, because itself is 100% powered by Air, instead of Electricity/Diesel, so it can work safely in explosive environment.

GN Technical Team also developed a mini Vacuum Pump, which is specially designed for bilge cleaning in shipyard. Generally there shall be workers to get down into the bilge to clean the residual at the bottom of tank, and use lifting barrel to transfer out the residual to the top of bilge. But with the help of GN Mini Vacuum Pump, there is no need of manpower. The workers can lay down the Pump to bilge, it can easily remove the sludge and pumps out, maximum reach 80meters.

Welcome to contact GN Sales Managers, and they would offer professional suggestions / customized One Stop Turnkey Solution for your project.

GN Company already supplied the Pump to UK, Norway, Greece, Russia, Portugal, Malaysia, Nigeria, Mongolia, UAE, Oman, Bahrain, Thailand, Mongolia, India, etc.

GN Company is open mind for cooperation and developing the market with local players. Welcome to contact GN Company, and talk about cooperation together.

Recently GN Company received orders from two Indian Companies for different models of Screw Press, used for different projects. One project is used for municipal sewage treatment, and another project is for oil sludge treatment.

Sludge dewatering Screw Press is a new type of sludge extrusion dewatering equipment, and its working principle is screw extrusion, through strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between floating ring and fixed ring, to realize solid liquid separation.

Comparing to Filter Press and Decanter Centrifuge, Dewatering Screw Press has advantages of low power cost (Electricity), small footprint, less investment, and operation cost, etc. It is more suitable for clients in Africa and India, where power (electricity) supplying is limited.

GN Company is capable to supply material for wetted parts based on Stainless Steel 304, 316, and Duplex Stainless Steel 2507 can be customized.

Besides supplying De-watering Screw Press, GN Company also supplies Chemical Dosing Unit (it can be suitable for either Powder or Liquid chemical) and Sludge Feeding Pump for Screw Press.

GN has rich experience in supplying integrated system solution, and GN technical team has also developed customized system with screw press and polymer dosing unit installed on Truck, so it is much more convenient to transport the equipment around different job sites.

This week GN Company completed production of one set of Dewatering Screw Press and Chemical Dosing Unit, and they would be shipped to client's plant for food wastewater treatment in India.

GN Dewatering Screw Press Features,

1. Screw Press can be widely used for sludge dewatering from different industries, such as Municipal Sewage, River Water, etc. And Screw Press can also be used for Oil Sludge Treatment.

2. Screw Press is working continuously and automatic, while it's not easy of blockage.

3. Comparing with other dewatering equipment, such as Decanter Centrifuge, Filter Press, Screw Press has advantages of low cost and power cost. And it is a compact structure with small footprint.

GN Company is capable to supply dewatering screw press with capacity ranging from 5kg/hour~640kg/hour, and supply material based on clients' requirement, including Stainless Steel 304, 316, Duplex Stainless Steel 2205.

Dewatering Screw Press is always used for sludge with solids content less than 5% and the solids are soft. For large Solids or hard abrasive slurry, GN Company suggest Decanter Centrifuge.

For most of dewatering project, Chemical Flocculent is widely used to concentrate tiny particles, which can help for better performance of dewatering equipment. GN Company can supply 3-Slot Dry Powder PAM Chemical Preparation Unit and Single Barrel Mixing Unit for PAC or PH regulating reagent. Dosing Pump is also available in the scope supply of GN Company.

Welcome to contact GN Sales Managers, and they would suggest the most suitable equipment for clients’ dewatering project.

3-Phase Decanter Centrifuge is used for Solids / Oil / Water separation, and based on GN Technical Team's experience, the separated oil from decanter has about 3% content of moisture + impurities. And if the fed sludge can be Solid < 10 % and Particle size < 2mm, there would be better performance. The Oil can be re-sale for Industry application, and water can be recycled in the system or discharged to city sewer system. And Decanter Cake can be used for Fertilizer or animal feed.

Here is working principle about 3-Phase Decanter Centrifuge

The centrifuge is composed of two rotors, one drum (2), and the other is screw (3). When the drum rotates at high speed, the slurry in the drum rotates with the drum and is subjected to centrifugal force. This centrifugal force is many times larger than gravity, so the solid particles will be separated from the liquid and settled on the inner wall of the rotating drum from the axis of the centrifuge drum. The screw rotates at a speed lower than that of the rotating drum and pushes the deposited solid particles to the slag outlet (1). The differential speed of the outer rotating drum and the screw (affecting the slag pushing speed) depends on the transmission ratio of the differential and its speed. The heavy-duty liquid has centrifugal force and is divided into two layers. The heavy phase layer is drawn against the wall of the drum by the centripetal pump (4) and discharged from the heavy phase outlet (6). The light phase layer is close to the spiral end, thrown out by centrifugal force from the overflow, and then discharged from the light phase outlet (5). The whole work is continuously completed between the closed upper and lower shells.

Welcome to contact GN Sales Managers for detailed solution for your project.
