●The performance testing conditions for liquid ring vacuum pumps are as follows:

The exhaust performance specified in the catalog is based on the test conditions where the inlet air temperature is 20°C, the outlet pressure is 760 Torr, the relative humidity is 75%, and the liquid seal water temperature is 15°C. If the actual liquid seal water temperature differs from 15°C, please refer to the exhaust performance correction table to adjust the actual exhaust volume accordingly. When operating beyond the redline area, the liquid ring vacuum pump may experience cavitation and generate noise and vibration, so please avoid using it under such conditions.
