This brochure provides basic information about ISO 21049 and API 682. It contains a set of checklists and summaries which give a brief overview that will help to select suitable EagleBurgmann sealing systems. ISO 21049 is an international standard which is based on API 682 (a standard of the American Petroleum Insti-tute). The content of these two standards is generally identical.

Both standards specify requirements and recommendations for the selection and operation of shaft sealing systems in new or retrofitted centrifugal and rotary pumps. They refer to pumps which are mainly used for hazardous, flammable and/or toxic applications in the petroleum, natural gas and chemical industries.

The improvement of equipment reliability and the reduction of emissions and life-cycle costs are the major targets of these standards.

The following table summarizes the history of API 682/ ISO 21049 and the pump standards API 610/ ISO 13709:

The API 682 task force of the American Petroleum Institute is the author of API 682. ISO 21049 has been created by the technical committees ISO/TC 115, SC3 and ISO/TC 67, SC6.

The checklists, summaries and API plans are based on both standards. For further and more detailed information please refer to the commercially available docu-ments of API 682 3rd edition and ISO 21049.

API 682 and ISO 21049 specify a range of different sealing systems. Parame-ters such as category, arrangement, configuration, type and API plans are to be considered.

The chart overleaf is a quick overview about the basic features of the different categories, arrangements and seal types. It also shows the links between these parameters and marks default and optional selections.

Step I: The category determines the applicable seal chamber, basic seal design features, maximum operating conditions, testing and data requirements. Each category has special demands regarding the seal arrangement, configuration and type. There are three different categories.

Step II: Determines the arrangement of the mechanical seal cartridges and their possible configurations.

The configuration determines the sealing method, orientation of the mechanical seal components, the use of containment seals and the required API plans. API 682 and ISO 21049 specify six default configurations and five optional configurations. Each of these configurations can be realized with different seal types.

Step Ill: Definition of the seal type, the design and material of the spring element and the secondary seals.It defines the appropriate operating limits. API 682 and ISO 21049 specify three basic seal types, a fourth option is a totally engineered sealing system (ES).

Step IV: Completes the sealing system classification by selecting the required API plan.

API 682 and ISO 21049 introduce a seal code which contains information about the category, arrangement, type and API plan. For further details please refer to page 27.

This chapter is dedicated to find the correct EagleBurgmann Sealing Systemaccording to API 682 / ISO 21049 standard.

Before beginning with the seal selection, some general information:API 682 and ISO 21049 specify defaults ( ) and options ( ) for several design details and the selection of the seal materials. The options are only permitted with the approval of the customer. Therefore typical seal codes always assume all standard defaults.The standards do not intend to prevent a vendor from offering or the customer from requesting alternative equipment or engineered products for special applications. This may be particulary appropriate where there are options, innovative or developing designs or materials. Further information shall be provided by the vendor if an option or any variations to this standard are offered.

How to select the EagleBurgmann sealing systemThe tables on page 11 and 12 describe two different ways to select the EagleBurgmann seal needed for a specific API-application.

Seal selection by seal features■■ The table on page 11 is used after the arrangement, configuration and seal type is defined. The table is structured in the same way as the API scheme on page 5. Going from left to right, the same three steps have to be made as described on page 4: by choosing the arrangement, configuration and type required. In the column “Flexible Element” you can see if “rotary” or “stationary” is the “default” or “option”. The “Mechanical Seal” column on the right lists the recommended EagleBurgmann seal type. Further down the page tables for some optional configurations, recommended API plans and a range of EagleBurgmann Supply Systems can be found.

Seal selection by media groups■■ API 682 and ISO 21049 define different media groups and typical service conditions. The tables on page 12 list EagleBurgmann recommendations for suitable sealing systems. Some of them include optional configurations. Specific applications may allow or require other seal arrangements and different API plans. Please contact us for further information. In the upper table the seal selection for standard seal types can be found. The table below is dedicated to optional seals.

Containment Seals Type A

A containment seal is a safety seal. In case of primary seal failure it shall operatefor a minimum of 8 hours at seal chamber conditions. It can be found in the default configuration „2CW-CS“ and the optional configuration „2NC-CS“

Containment seals can be of non-contacting or contacting kind. Non-contacting containment seals feature aerodynamic grooves which providea reliable lift-off of the seal faces even at low velocities. Contacting containment seals are used in connection with liquid buffer systems but may also be used as dry running seal in connection with a Nitrogen purge.

Operating limitsp1(max) = 2 bar g (29 PSI), dry operationt1 = -40 … 176 °C (-40 … 350 °F)vg(max) = 23 m/s (75 ft/s)

In the event of primary seal failure the EM300 will work as a conventional wet lubricated seal in pressures up to 60 bar g (870 PSI) for at least 8 hours.

An API plan determines the piping or auxiliary system which is connected to the seal chamber or/and the mechanical seal cartridge. Certain seal configurations only work in combination with appropriate API plans. Other API plans can also be applied to improve the performance of a mechanical seal. The combination of external control and supply units which are used to realize a certain API plan is usually called a “Supply System”.
