Api 4 th edition piping plans
API and ISO specify a range of different sealing systems. Parameters such as category, arrangement, configuration, type and API plans are to be considered. The chart is a quick overview about the basic features of the different categories, arrangements and seal types. It also shows the links between these parameters.

Features 1. Removes heat from the seal chamber as well as acting as a vent connection in horizontal pumps. Use 1. Recommended in clean fluids. Recommended for fluids which thicken at ambient temperature. Caution 1. Ensure that the recirculation is sufficient for seal heat removal.
Applicable to low seal chamber pressure and process temperature. Can be used with tapered seal chambers, especially for slurries. Normally is used along with a jacketed seal chamber. In cool clean fluids with high specific heat, such as water, in relatively low speed pumps. To avoid flashing, process fluid temperature must be taken into consideration.
Ensure top point vent in throat bush for cylindrical chambers in horizontal pumps. The mechanical seal is cooled by product flow created by seal chamber design.
Seal chamber design provides improved venting of air or vapours. Typically, the seal chamber is tapered and does not have a throat bush. Generally used in applications where there is not significant seal heat generated. Where solids could collect in a traditional seal chamber.
Not suitable for cylindrical bore seal chambers. May not be suitable for high pressure or high temperature seal chambers.
Prevents product from vaporizing api 682 pdf free download maintaining positive pressure above vapour pressure. Becomes a self-venting plan for horizontal pumps, api 682 pdf free download. Default API Plan for most single seals. In general, applications with clean non-polymerizing fluids with moderate temperatures.
Calculation of recirculation flow rate, heat removal and orifice size are required. Check the margin between discharge pressure and seal chamber pressure to ensure proper flow of fluid. Do not use with media containing solids and abrasives. Can handle dirty liquids to some extent. In general used in slightly dirty and non-polymerizing fluids. Always ensure that api 682 pdf free download is placed after the Y strainer. This plan is normally discouraged due to unreliability of Y strainer.
Calculation of recirculation is required. Provides continuous vent for vertical pumps. Wherever Plan 11 is not usable due to low-pressure margin between discharge and seal chamber pressure. Used in vertical pumps. Check margin between seal chamber pressure and suction pressure. Ensures product recirculation as well as venting. Increase cooling of seal chamber. Combination of plan 11 and plan Used in light hydrocarbon services. Check for pressure margin between discharge to api 682 pdf free download chamber pressure and seal chamber to suction pressure.
Improves pressure margin over vapour pressure. Improves temperature margin to meet secondary sealing element limits, to reduce coking or polymerizing and to improve lubricity. Self venting plan. Provides sufficient pressure difference to allow proper flow rate.
For high temperature applications e, api 682 pdf free download. In hot non-polymerizing fluids. Always ensure that cooler is placed after the orifice. Check pressure difference between discharge and seal chamber.
Cooler duty is high leading to fouling on waterside. Potential plugging on process side if fluid viscosity rises quickly.
For high temperature applications with slightly dirty liquid. This plan is normally discouraged due to non-reliability of Y strainer.
Circulation is maintained by pumping ring. In idle condition heat transfer is maintained by thermosyphon effect and in running condition by a pumping ring. Lower product stabilization temperature is achieved. Establishes required margin between fluid vapour pressure and seal chamber pressure. In hot and clean services e. Maintain maximum 0.
Vent valve required at highest point of piping system, api 682 pdf free download. Ensure that pump has a close clearance throat bush. Ensure that the seal outlet connection is in the top half of the gland. Ensure that the cooler is mounted above the pump centre line. Vent the system fully before start up. Removes entrained solids from the process fluid.
Particles from cyclone separator are returned to suction. Used in media with suspended solids. Pump throat bushing is recommended, api 682 pdf free download. Ensure use for services containing solids with specific gravity twice or more than that of process fluid.
Efficiency of a cyclone separator is proportional to the diameter. A larger cyclone diameter leads to less efficient separation, a smaller cyclone diameter provides more efficient separation. Reduces flashing or air intrusion across seal faces by providing a positive flush. Maintains vapour pressure margin. Always provided at a pressure greater than seal chamber pressure. If maintained properly the best of all single seal plans subject to acceptance of contamination.
Dirty or contaminated fluids. High temperature applications. Polymerizing and oxidizing fluids. Media with poor lubrication properties. External source should be api 682 pdf free download and reliable at all times, even during start up and shut down. Flush fluid must be compatible with process fluid due to product contamination. Product degradation can occur. Ensure use with close clearance throat bushing to maintain pressure in stuffing box and control the rate of contamination of pumped media.
Careful selection of flush fluid required to ensure that it does not vapourised on entering the seal chamber. Fluid expenditure of Plan 32 may be as expensive as one or more seals per year, api 682 pdf free download. Improves pressure margin to vapour pressure. In hot services containing suspended solids.
Circulation is maintained by using pumping ring in running condition and by thermosyphon effect in stand still condition. No process contamination. No direct process leakage to atmosphere. No need to maintain pressure system as in Plan 53A.
