API 682 – Plan 53B

Enjoy the Flopac performance and treat your equipment by selecting the Flopac® series SPB-5__ seal support systems.

The range of Flopac® SPB seal support systems include plan 53B seal flushing units that are typically used with arrangement 3 contacting wet seals (3CW-FB, 3CW-BB, 3CW-FF).  

Plan 53B seal support systems are closed loop piping systems that circulate barrier liquid between a pressurised dual seal arrangement – to cool and lubricate the in- and outboard seals. The closed loop is provided with a gas-loaded bladder type accumulator to maintain the barrier liquid a higher pressure than the process pressure in the seal chamber. This offers the highest level of safety eliminating process leakage entirely.
