PLAN52  

Plan52  is mainly used for tandem mechanical seal, the non-pressurized buffer fluid passes through the liquid accumulator, and the pumping ring in the cartridge seal provides

circulation power. It is mainly used in easily vaporized, flashing hydrocarbons and dangerous, toxic and harmful media. The buffer fluid pressure in the liquid accumulator is normal

pressure. If the seal on the medium side leaks directly into the seal on the atmosphere side, the pressure in the liquid accumulator increases and is then discharged from the exhaust line.

The seal leakage can be judged by the liquid level shown by the liquid indicator on the liquid accumulator. The choice of buffer fluid should be consistent with the properties of the process

medium. The pressure switch is set to high pressure alarm, and the alarm value is usually: 0.1Mpa.
