Mechanical Seating Sucker Rod Pump Description
 

The complete pump designation of an API pump adds dimensional diameters and lengths to the letter designations. This has been modified in the latest revision to incorporate all approved sizes and barrel types along with separating the extensions into the top and bottom lengths, if required. The complete API designation includes the following:

• Nominal tubing size (from 1.9- to 4.5-in. OD) - represented with 2 digits
• Basic bore diameter (from 1.0625 to 3.75 in.) - represented with 3 digits
• Type of pump (rod or tubing) - R or T to indicate type
• Type of barrel (heavy, thin, or X type) - single alpha character to represent the barrel type
• Seating-assembly location (top or bottom) - A (for top), B (for bottom), or T (for bottom, traveling barel)
• Type of seating assembly (cup or mechanical) - C or M to indicate type
• Barrel length (ft) - single digit length
• Nominal plunger length (ft.) - single digit length
• Length (in.) of upper extension (if required)- single digit length
• Length (in.) of lower extension (if required)- single digit length
