In Plan 53A there is a pressurized external barrier fluid reservoir supplying clean fluid to the barrier fluid seal chamber. The barrier liquid is maintained at a pressure greater than seal chamber pressure.

Advantages:

  • Self-contained process fluid
  • Zero emissions

Applications:

  • Hazardous fluids
  • Toxic fluids
  • Heat transfer fluids
  • Abrasive or polymerizing fluids
  • Used with dual pressure seals
  • High vapor pressure fluids, light hydrocarbons
  • Mixers agitators and vacuum mechanical seals

Note

Plan 53 is usually chosen over Plan 52 for dirty, abrasive, or polymerizing products which would either damage the seal faces or cause problems with the buffer liquid system if Plan 52 were used. Use the STB TS-9/TS-12 for better operating conditions.

NSE 53

Designed especially for mechanical seals in high pressure surroundings, where an interruption of the barrier fluid is not allowed. These backfeed systems are designed to supply many mechanical seal support system or a number of mechanical seals by only one system. Over the past years, these types of systems have shown in field, to increase the lifetime of mechanical seals heavily.
