Heavy-duty baseplates, casing jackets, and various levels of performance testing are also available.

Together, these features combine to produce some of the most efficient hydraulics in the industry and shaft deflection values meeting or exceeding those of API 610 requirements. The API Maxum OH2 is also available as an OH1 design for lower temperature applications.

A seal code is an abbreviated method of communicating basic specifications for the mechanical seal. Sadly, the seal code has been changed with every edition of API 682.  Fortunately, the new code, described in API 682 4th Edition Annex D, is the best to date and includes some concepts and codes from the historical API 610 seal code. The new code uses eight fields:

API 682 4th Edition was the first edition to include materials in the description and in many ways represents a combination of API 682 coding and the old API 610 codes.

4th Edition coding comprises four sections, some being sub-divided.  The table below shows the construction of a typical seal code, it is intended to accurately describe the seal and seal system being implemented in a given application.

T:  Seal type A, B or C per API 682 4th Edition definitions.  For dual seals using different inner and outer seal types, show both types using the format inner/outer.

Note that the codes used for Design Options are the same as those used in API 610 for materials that are included in both systems.  On the other hand, some materials cannot be specified because API 682 does not recommend them.  Such materials must be specified with an “X”.

For many years the pump standard API 610 contained a mechanical seal coding system which became widely used in industry. This coding method provided a reference to the nomenclature and features used with mechanical seals that were current during that time period. While this coding method is obsolete it still is still being used in some areas of industry. It is presented herein as a historical reference only.

A very commonly used code was BSTFM which translates to a balanced single seal with throttle bushing in the gland plate.  Gaskets would be FKM (fluoroelastomer).  Seal faces would be carbon vs nickel bound tungsten carbide.

API 610 is the American Petroleum Institute’s standard for ultra-reliable process pumps. The standard was born out of the needs of refineries, which no doubt present some of the most difficult conditions—high-temperature hydrocarbons with very high reliability and safety requirements. Although refinery pumps are in API 610’s DNA, the standard is applied in a variety of other industries and processes that require mission-critical pumping.

Many facility operators and engineering firms use API 610 as a starting point and add their own company and process-specific overlays, which allow the API spec to be tailored to a variety of refinery and non-refinery applications. Because many of these non-refinery applications present different conditions, the off-the-shelf API spec may not be entirely appropriate. In fact, 100% adherence to the standard might result in a pump that is over spec’d for the application.

To help customers determine how much of the standard to adopt, we compare two versions of our Maxum engineered pump: a fully-compliant Maxum API 610 pump vs. a Process Maxum version with some features removed. Although any particular application may require some customization, the feature sets below give a feel for some of the design features included in API 610.

API 610, Section 6.4.3 requires auxiliary casing connections other than the seal gland to be a flange that is either integral, socket or butt-welded. Like many requirements of the standard, this is intended to ensure safety when hazardous fluids are present. For less hazardous processes, NPT connections may be sufficient.

The API 610 covers the design of the chamber and surrounding geometry but offers little guidance on the selection of seals. For seal design and selection, there is a separate standard, API 682. Needless to say, seals can be very expensive and it makes little sense to buy too much seal for the application.

API 682 specifies detailed requirements for the seal support system. The 4th Edition guides toward the use of pressure transmitters rather than switches. Lower cost options are available, especially if allowed by the temperature and pressure requirements of the process.

Section 6.10.2.2 states that bearing housings must have a constant-level sight-glass oil feeder of at least 4 fluid ounces. It covers a number of other bearing lubrication schemes, such as oil mist, which would of course preclude the use of a constant-level oiler. At Carver, we include constant-level oilers as standard for our API 610 OH2 pump, and a bullseye sight glass as a cost-saving option on the process version of the pump.

Section 7.3 requires a number of design features, including accommodations for contained drainage and continuous seal welding of all seams on both sides, to contain corrosion. Our fully-compliant baseplate has extra structural reinforcement to meet the shaft deflection requirements of the standard. However, depending on the installation, some of these features may not be necessary.

Section 10 of API 610 is fairly generic and allows for documentation that meets the engineering requirements of the project. While the rules do not seem overly onerous in this respect, in our experience, software delivery has the potential to contribute greatly to the cost of a pump. Additional testing, calculations, data books, and their associated revisions can add significant costs.

The features described above are just a sampling of the hundreds of design requirements outlined in API 610. At Carver Pump, we believe in meeting the unique needs of each application, without adding on unnecessary and costly extras. API Maxum Techbook
