In an API plan 52 - 53 system, a pumping ring, which is included in the seal design generates the flow. The resistance in the system will determine the flow through the system; therefore special attention must be paid to the execution of the interconnecting piping between the system and the mechanical seal.
The following connections should be made:
1) Barrier/Buffer liquid line to mechanical seal (A)
The to seal connection should be connected to barrier inlet connection on the mechanical seal flange.
2) Barrier/Buffer liquid return line from mechanical seal (B)
The ‘From Seal connection’ should be connected to Barrier outlet connection on the mechanical seal flange.
3) Filling connection (F)
The filling connection should be connected to a filling line or a filling unit
4) Nitrogen / Flare / Vent connection (V)
In case of a plan 53 system the nitrogen inlet connection should be connected to a nitrogen supply line.
In case of a plan 52 system the flare connection should be connected to a safe disposal point or the flare.
5) Cooling water connections (CI/CO)*
When needed, connect cooling water to the cooling water connections
