For oil and water separation, there are oil water separator, three phase centrifuge and etc. And there is also chemical dosing system which is used to help with separation. For conveying equipment, GN produces screw conveyor and various pumps, including shearing pump, centrifugal pump, submersible slurry pump and screw pumps. Among all the pumps, the vacuum pump is a quite special one and also the most popular one.

1.GN Vacuum Pump is fully air driven, that’s why it is called vacuum pump. It is generated by an air compressor, with a negative force, it can suck in the material. And with a positive force, it will push out the material to a certain distance. It needs no electricity at all, so it is fully explosive proof.

2.GN vacuum pump is also called a solid pump, because it can handle solids particles easily, as long as the particles can pass the pipelines. The material to be transferred need to be liquidate, while liquid is not a must. For example, the sands or small stones can be transferred by the vacuum pump easily.

3.GN Vacuum pump can be used for different applications, including oily sludge industry, refinery, animal waste, chemical transferring, minerals, coal powders and etc.

Clients from different industries are coming to GN for purchasing this pump. That’s why, for the 3 standard models, GN are making stock for quick delivery for clients. Please contact GN team for confirming the soonest delivery time.

About GN Solids Control

1. The pump is fully air driven. Yes, exactly, cause the solids pumps are really designed as a vacuum cleaner, and it has another name, which is a vacuum pump. It is called a vacuum pump because it is driven by air and helped by an air compressor. The air compressor generated a gas force to the pump and the pump uses travel valves, delay valves and some other parts to suck and push the materials in and out by using the compressed air. Instead, a vacuum pump itself has no need for electricity.

2. Features of vacuum pumps. The air force is high, so the pump is quite powerful. For example, the largest vacuum pump is GNSP-40B among GN vacuum solids pumps and it can suck materials from 500 meters far and discharge to up to 1000 meters away. Even the half sized GNSP 20B can discharge the material to 500 meters distance.

3. Special functions for a mini vacuum pump. Comparing with a large vacuum pump, the mini pump is more compact in structure and equipped by some wheels for easy movement. With a handle, it can be dragged from here to there, just like when you are using a vacuum cleaner at home. GN provides 3 types of inlets for the vacuum pump to make it suitable for different materials.

Mini Solids Vacuum Pump and Mini Decanter Centrifuge for International Customer

When you talk about something mini, what do you think? For example, a mini iphone 13, what image do you think? Yes, of course, a mini something means the same function with a more compact structure, a portable one or at least more flexible one. Have you ever considered a mini solids vacuum pump or a mini decanter centrifuge? In fact, just days ago, GN has supplied to an international customer such equipment, both in mini sizes, a vacuum pump and a decanter centrifuge.

2022.04.01 Mini Solids Pump

1. Solids vacuum pump. A solids vacuum pump is a quite powerful pump which is used for transferring medium with large particles. It is widely used in many different applications and places because of those features: first, it allows material with quite large particles with only limit as the pump’s pipeline diameter. Second, it can transfer to a quite large distance, for example, a small pump can transfer water to 500 meters away horizontally, and a large pump of 40cbm per hour, can even transfer water to 1000 meters away. Thirdly, it is suitable for different Explosive Proof conditions cause it is not driven by electricity.

A mini vacuum pump is equipped by wheels and a handle, which is flexible to be used for tank bottom cleaning by insert its inlet pipe into the tank.

2. Decanter centrifuge. Decanter centrifuges are quite efficient machines used for separating the solids particles from liquid thoroughly. The cutting point is determined by the bowl rotating speed. A middle speed decanter centrifuge can separate particles from 5 to 7 microns while a high speed one can remove particles from 2 to five microns. The decanter centrifuges’ capacity depends on the centrifuge size, especially the bowl diameter. The larger diameter it has, the larger capacity it can handle. A mini decanter centrifuge in GN equipment range is a 9 inch diameter one, and GN has all popular models available, such as 14 inch, 18 inch, 22 inch and even 30 inch.

This client who purchased both mini vacuum pump and mini centrifuge is planning to use those equipment for tank cleaning, respectively for pumping out and treating of the sludge.

How to Operate on a Vacuum Pump to Its Best

As is known to all, a vacuum pump is a powerful pump which is suitable for different applications. Because it can transfer material with large particles or large solids content, it is also called a solids pump. It is fully air-driven by connecting to an air compressor. The working principal is to suck in the material with the negative force and push the material out with a positive force.

If it is operated in correct method, it can reach a quite ideal performance. Here are some tips:

1. Suitable air supply for the vacuum pump:

There are 2 requests to meet for the air compressor: pressure between 0.6~0.8 Mpa, and a large enough air volume.
In some cases, although the air compressor can produce an air pressure of 0.6 Mpa or above, during operation, reading on pressure guage is only 0.4 or 0.5Mpa.
This problem could be solved by reducing the air hose length from air compressor to the pump, or using a larger diameter air hose.
Another option is an air container. Since the ideal operating air pressure should be stable around some value between 0.6 to 0.8 MPa. In some cases, when the air supply from an air compressor is not stable, you can use an air container matching to the air compressor. It is located in between the compressor and pump.

2. Time setting for loading and discharging:
For both loading and discharging, there is a time range from 0 to 30 seconds. This time setting can be adjusted during operating, which depends on many factors including material character, distance, pipe diameter and etc.
For example, if the sucking time is set at 25 seconds, and when pump is sucking, at first the material goes quite quickly, then it slows down gradually.
When the material moving nearly stops, the pump is almost full. You read the time and you can set the sucking time accordingly.
During discharging, make sure the material is fully pushed out from the discharging hose. Don’t leave heaps of material to stop at half. In that case, it will hinder the later sucking and discharging.
You can contact GN Solids Control, the vacuum pump manufacturer, for more information.

GN Screw Press Dewatering and Solids Vacuum Pump for ES Company

In the past years, the sludge treatment works are becoming more and more important because of the focusing on the environment protection. The environment protection in this field includes how to make the sludge less polluted before safely discharge. That’s why the efficient solutions for such sludge become more and more popular.

2021.10.15 Screw Press Dewatering Machine

1. Screw press sludge dewatering:

Screw press sludge dewatering machines are coming more and more welcomed to clients. Screw press dewatering is a kind of economic choice which is also quite environmentally friendly. The working principle is just like when you are twisting a wet towel. The motor will generate a strong force for squeezing the wet sludge by changing the screw diameter and screw pitches. The tiny gaps between floating ring and fix ring will do the squeezing work, to leave the sludge into liquid and cakes. Comparing with other separating equipment, the screw press dewatering machines don’t need chemicals and will sure leave less contamination to the surroundings.
In a recent project, an ES Company purchased from GN Solids Control such a screw press dewatering and a vacuum pump.

2. Solids vacuum pump.

A vacuum pump is also called a solids vacuum pump, which allows in material with high solids content, even dry sand, just to make sure that the material largest particle size is within the limit as pump inlet diameter.
The solids vacuum pump can transfer the material to more than 50 meter away. It is fully air driven, no need for consumption of electricity itself. That’s why it can be located at Explosive conditions by being linked to an air compressor.

Based on your jobsite condition, GN Solids Control can offer customized designs with rich experiences and professional engineer team. For more information, welcome to contact GN sales team directly.

Vacuum Loading Solids Transfer Pump to Europe Client

You might not have heard about a vacuum loading solids transfer pump because of the long name used for describe such a powerful pump. But if I mention about a vacuum pump, a solids pump, an air driven slurry pump, it becomes familiar for you. Cause in recent years, those vacuum loading solids transfer pumps are becoming so popular.
This transfer pump can handle for different applications, for wet materials including but not limited to: oily sludge transfer, slurry transfer, tank bottom mud cleaning, animal waste and etc. For dry materials, it can work even better and wider with active carbon, sands, small stones and etc.

2021.08.24 Solids Transfer Pump
This solids pump allows in quite big particles, that’s why it is called a solids pump. The only limit to the incoming material size is the pipe diameter, and GN Solids Pumps can handle particles up to 75mm with a GNSP-40B pump.
It is also called a vacuum pump because it is driven by air only. It doesn’t have a motor for energy, instead, it uses compress air for make a vacuum inside the pump and suck in the material, and also, it pushes out the material with air force. That’s why it is suitable for explosive environment.

Which model is most suitable?
It depends on several factors:

1. Distance from the material’s original location and the distance to where you need to transfer the material. A GNSP-40 vacuum pump can even deliver the material to 1000 meters away, and the smaller models can deliver to 500 meters.
2. Transferring capacity: there are 3 optional models respectively with capacity of 10 cbm per hour, 20 cbm per hour and 40 cbm per hour.
3. Movable or not: if the jobsite is comparably fixable, and you need a larger capacity, then the GNSP-40B will be the most suitable. Well if you need to move the pump as a pulley, the GNSP-10B and GNSP-20B are more suitable cause they are equipped with wheels.
