Api Subsurface Tubing Pump

We are engaged in manufacturing, exporting and supplying excellent quality API Subsurface Tubing Pump to our valuable clients. 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
