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.

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.
The Thermosiphon TS-9 is designed for the barrier fluid supply for mechanical seals. The main application areas are single mechanical cartridge seal with integrated throttle bush or double mechanical cartridge seals.

Also available as Plan 52 without pressure
The Thermosiphonystem TS-12 has a high volume for the barrier fluid supply for mechanical seals and additionally has a higher pressure range. It is available with a variety of options, like an integrated cooling coil, which has a higher cooling capacity.

53B with pressure
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.
