⭕️API PLAN 14⭕️
✔️Description
Product recirculation from pump discharge to seal chamber through a flow control orifice and seal chamber back to suction through another flow control orifice.
✔️Features
1. Ensures product recirculation as well as venting.
2. Reduces seal chamber pressure.
✔️Use
1. Used in vertical pumps.
2. Used in light hydrocarbon services.
✔️Caution
1. Check for pressure margin between discharge to seal chamber pressure and seal chamber to suction pressure.

⭕️API PLAN 23⭕️
✔️Description
This plan involves the forced circulation of process fluids from the seal chamber through a seal flush heat exchanger and back to the seal chamber.
✔️Application Notes
Seal has an internal circulating device (pumping ring) that circulates seal chamber fluid through a cooler and back to the seal chamber.
Provides a cool flush to the seal to improve lubricity, reduce coking, and/or avoid fluid flashing to vapor.
Commonly used for hot water services above 180°F [80°C] (e.g. boiler feed water) and hot hydrocarbon services.
Throat bushing is used to isolate product in the seal chamber from product in the pump volute.
More energy efficient than Plan 21 since only the fluid in the seal chamber is run through the cooler.
If the cooler duty is high, fouling and clogging on the water side can occur over time.
Potential for clogging on the process side if the fluid becomes too viscous at reduced temperature.
Best piping practices must be followed to avoid vapor entrapment and stalled flow in the tubing.
✔️Pros:
Improved energy savings compared to Plan 21
Cool flush improves seal lubricity and reduces coking
✔️Cons:
The use of products with a high viscosity can negatively affect fluid circulation
Maintenance of the Seal Cooler although better than Plan 21
