JM-G6310R series mechanical seal auxiliary system (pressure tank system) is mostly used in series sealing, provide isolation buffer, control sealing normal work pressure and remove heat, reduce the sealing end temperature, improve the seal lubrication conditions, establish an ideal working environment for sealing, thus greatly improve the reliability of mechanical seal work. With monitoring window and detection alarm device interfaces, it can provide manual rehydration pump, pressure switch, pressure alarm and liquid level relay components according to different requirements to ensure that the prevention medium will not be directly leaked into the atmosphere to protect the environment.
