This system is ready to leave to a client who manufactures beauty products, however due to the pandemic switched production to antibacternail chemicals.

For their strenuous production we have selected the liquid ring technology for a number of reason. 

Due to their simple and robust design, liquid ring vacuum pumps are suitable for vacuum generation in applications where moist gases or vapours are evacuated or where condensation inside the vacuum pump tends to take place during the compression process. This makes them ideal for wet processes and are the system of choice for low vacuum generation in process technology, the chemical industry and many other industrial applications.

Due to the operating fluid, the liquid ring vacuum can only be used between 33 mbar and abs.  pressure. The reason for this is that the achievable vacuum level depends on the vapour pressure of the operating fluid which is pumped constantly through the vacuum pump. This allows a liquid ring vacuum pump to be operated at relatively low temperatures; in addition, the temperature rise of the medium is kept to a minimum during the compression process.

Liquid ring vacuum pumps are  perfect for pumping vapours and gases with a high moisture content. For optimum performance low service liquid temperature is recommended for the condensation of vapour. Due to this  vacuum pump can simultaneously functions as a condenser and because condensation takes place when the mixture enters the vacuum pump, the volume is drastically reduced. Apart from the condensation effect, this also results in an increase in the nominal pumping speed.

The operating fluid absorbs the heat of compression and since liquid ring vacuum pumps are virtually isothermal, they offer advantages when pumping temperature sensitive products such as polymers.

One significant benefit of liquid ring vacuum pumps is that both the operating fluid and the materials used for the components can be adapted to fit the medium being pumped. Corrosive or explosive gases and vapours can thus be pumped, too. Due to the low operating temperatures, pumping explosive materials can, in any case, be considered much less problematic than with other mechanical vacuum pumps. 

To further extend our application base we can now offer ATEX 3G/3D certified liquid ring vacuum pumps.
