Using a tandem-type mechanical seal will result in a double seal structure, which will make it possible to further reduce the amount of leakage to the atmosphere.
Also, installing ancillary equipment (reservoir tanks) at the same time will make it possible to detect liquid leakage, so the pump can be stopped safely before large-scale problems occur.

Over load (Overcurrent) occurs.
