Objective
- API Plan 32 is used to provide a cool external flush to the remove the solid particles past the throat bush back to pump suction.
- Plan 32 in conjunction with close–clearance throat bush helps in isolating the solid particles to reach the seal faces
- Plan 32 is used when a process stream is difficult to condition is a way that will provide adequate cooling and lubrication to the mechanical Seals.
Advantages
- Increased Seal life as only clean process liquid is available to the seal faces
- Improved MTBF for the pump system
- Solids from the process liquid is removed ensuring clean environment around the Mechanical Seal Faces.
- Product temperature is reduced which enhances the performance of Mechanical Seal
- With by-pass line for strainers and flow- meters, they can be repaired while plan 32 in operation itself.
Technical Features
- Throat bush design is critical so as to ensure minimum velocity of 32 feet/Sec for the plan 32 external fluid.
- Pressure of plan 32 liquid to be maintained at higher pressure than box pressure, preferably 2 Kg/Cm2 above box pressure.
- Check valve or Non-Return valve in the Seal inlet line to prevent reverse flow of the process liquid into the plan 32 system.
- Plan 32 employs PCV to ensure downstream pressure required for Mechanical Seals
- Optional Heat exchanger may be employed if the variable external clean liquid is at higher temperature
- Use of pressure transmitter in the piping can be used for monitoring the seal failures
- Employment of strainer ensures clean liquid availability to the mechanical seal
- Flow – meter used in the line can be used to know the flow-rate of the plan 32 liquid
