Plan 53A

  • 53A

  • PLAN 53A is used for the double  seals of arrangement 3 seal , that is, the pressure of the isolation fluid is higher than the maximum pressure of the seal chamber and at least 0.14MPa (20psi) higher, which can be achieved by flushing nitrogen at the top of the reservoir;

  • This scheme is usually used in services where no leakage to atmosphere can be tolerated,It may also be selected for applications where the pump may be operated dry or the pump process fluid may be damaging to the seal faces.

  • Piping Plan 53 is usually chosen over Piping Plan 52 for dirty, abrasive, or polymerizing products that would either damage the seal faces or cause problems with the buffer liquid system if Piping Plan 52 were used.

  • The clean barrier liquid provides lubrication to the seal faces, but the barrier liquid that passes across the inner seal faces will enter the pumped process stream. Therefore, the process liquid shall be compatible with the barrier liquid and be able to tolerate a small amount of contamination from the barrier liquid.

  • The liquid storage device is installed inside the serpentine coil, can be real-time buffer cooling;

  • The front of the liquid storage device is equipped with glass plate liquid level gauge, and with high and low liquid level alarm position, convenient real-time observation of liquid level change;

  • The liquid storage device is equipped with funnel type filling cup and each quick open ball valve, convenient operation and maintenance.

  • Optional all kinds of instruments, such as thermometer, pressure switch, liquid level switch, pressure transmitter, liquid level transmitter, etc. Can realize the scene alarm, also can transmit the data to the PLC control panel, better monitor the operation of the mechanical seal.

  • Optional manual replenishment pump, can be in the case of equipment does not stop, real-time manual replenishment and pressure.

  • The back bracket adopts the design of hanging ear, which is convenient for on-site installation and disassembly.
