Automatic Liquid Separator for Vacuum Pump |Auto Liquid Trap for Vacuum Pump
Automatically separate liquid without interrupting the vacuum circuit, Automatic Liquid Separator for Vacuum Pump, also called Vacuum Automatic Liquid Separator or Vacuum Automatic Air-liquid Separator, is installed between the vacuum table and vacuum pump, which will automatically separate the cutting fluid sucked into the vacuum table. Prevent the cutting fluid from entering into the vacuum pump and protecting the vacuum pump.At the same time, it has the function of filtering cutting chips. Automatic Liquid Separator for Vacuum Pump does not need to access the positive pressure gas, only low power supply can drive the work of Automatic Liquid Separator for Vacuum Pump. The discharge process does not cause pressure reduction, ensuring that the vacuum table maintains its clamping force. It is not only used in the CNC milling machine industry, but also in other scenarios where the liquid needs to be automatically separated from the vacuum pump. If your vacuum pump does not have the function of automatically separating liquid, it is necessary to install a Automatic Liquid Separator for Vacuum Pump at the front of the vacuum pump, which can also be used in the middle of the vacuum generator and vacuum table.
This Automatic Liquid Separator for Vacuum Pump can be used on all types of vacuum pumps including Liquid Ring Pump, Piston Pump, Rotary Vane Vacuum Pump, Screw Vacuum Pump.

How to use a vacuum liquid separator to stop cutting fluid from entering the vacuum pump?
Automatic Liquid Separator for Vacuum Pump would be a good choice. In the United States, it is usually called a vacuum liquid trap. In Europe, people usually call it a vacuum coolant separator. In China, people usually call it a vacuum automatic drainer. Of course, this is just a different name in different places. But the role of this device is the same. It is to achieve fully automatic separation of liquid. Without suspending the processing operation, the liquid is automatically separated from the vacuum hose or vacuum tank, and the vacuum pressure will not be reduced. The clamping force of the vacuum table is maintained.
The Automatic Liquid Separator for Vacuum Pump uses the principle that the density of liquid is greater than that of air to separate the liquid with the help of gravity. It mainly separates the liquid without reducing the vacuum pressure through the separation and switching of multiple chambers. And during use, due to the presence of debris in the cutting fluid, a filter cup needs to be installed at the front end of the Automatic Liquid Separator for Vacuum Pump.
Connection location of Automatic Liquid Separator for Vacuum Pump


If there is only one vacuum pump and one vacuum table, and the vacuum flow rate does not exceed 700L/min (25CFM), and the separated liquid flow rate is less than 5.2L/min. The connection scheme on the left is recommended. If the vacuum flow rate of the vacuum main manifold exceeds 700L/min (25CFM), or the liquid flow rate to be separated exceeds 5.2L/min. The connection scheme on the right is recommended. For the scheme on the right, if the separation capacity of one Automatic Liquid Separator for Vacuum Pump cannot meet the requirements, multiple vacuum pump automatic liquid separators can be connected in parallel to improve the liquid separation capacity.
What are the features of Automatic Liquid Separator for Vacuum Pump?
1. The process of separating liquid does not reduce vacuum pressure.
2. Small size, portable.
3. While separating liquid, it can filter out cutting debris.
4. The separated liquid can flow back to the CNC milling machine sink.
5. Low power consumption, energy saving and electricity saving.
6. Stainless steel inner wall, the inner cavity will not rust after long-term use.
7. Affordable, will not increase the cost much.
8. No need to do any settings before use, just connect the power supply and air pipe and you can use it.
9. Fully automatic liquid separation, the more liquid enters, the faster the liquid separation speed.
What are the precautions for using Automatic Liquid Separator for Vacuum Pump?
1. Since it is a gravity-type cutting fluid separator, the Automatic Liquid Separator for Vacuum Pump must stand vertically during use. Tilt-type use is not allowed.
2. For the needs of larger vacuum flow rates, it is necessary to make a good selection.
3. Choose a suitable installation location to ensure that the liquid separation requirements are better met.
4. If there are debris mixed in the liquid, a filter cup must be installed at the front end of the Automatic Liquid Separator for Vacuum Pump. If the cutting debris enters the Automatic Liquid Separator for Vacuum Pump for a long time, it will cause the seal between the chambers of the Automatic Liquid Separator for Vacuum Pump to fail.
Can the automatic liquid separatior for vacuum pump be customized?
