Mini Solids Pump and Mini shaker for South America Customer

Each year, GN Solids Control makes and sells tens of solids pumps in different sizes. The solids pumps are widely used in many industries, like the oily sludge transfer, slurry transfer, sand transfer even containing small stones, animal waste and etc. Some clients are even using a small sized mini solids pump for cleaning the waste on bottom tanks, during which the solids pump could serve the function as a vacuum cleaner we daily use in houses.

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.

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.

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.

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.
