Small Model Mechanical Seating Sucker Rod Pump Description


While there are only two main types of pumps standardized by API, there are four different types of rod pumps. These are classified by the type of barrel (standing or traveling) and where the pump is anchored (top or bottom). API Spec. 11AX. shows the letter designations for the various types of rod and tubing pumps that are available for different barrel thicknesses and either metal or soft-packed plungers.

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

Pump components


Standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and the fittings that hold the assembled pump together.


Allowable setting depth

In the early 1990s, an industry task group analyzed the stresses that react on a downhole rod pump. This was required to determine if there were recommended allowable loads that could be subjected to rod pumps of different types, sizes, and metallurgy. This group developed the burst, collapse, and axial-loading equations to determine these limits and the associated maximum recommended setting depth for sucker-rod lift pumps, [4] published in API RP 11AR.[1] The depth limitation and stresses on the downhole pump barrel and components should be considered when selecting the size, type, and metallurgy for a downhole pump.
