30-275-THBM Bottom Seating Tubing Sucker Rod Pump

HBM Bottom Seating Tubing Sucker Rod Pump Description

API recognizes two main types of pumps: rod and tubing. Rod pumps also are called insert pumps because they are run (inserted) in the production tubing. Tubing pumps are so named because the working barrel of this pump is coupled with the production-tubing string.

There is a wide range of plunger (or pump-bore) sizes standardized by the industry. The API pump-bore sizes that are currently available range from 1 1/16 to 3 3/4 in. in diameter. This 1 1/16-in. size has been added back in the latest edition of the standard. Additionally, a new barrel type has been accepted in the latest API Spec. 11AX. This is the "X-type" barrel. It has a thin-walled barrel configuration for threads on either end of the heavy-walled barrel and is available for metal plungers only. This type of pump does not require the extension couplings normally needed for heavy-walled barrel pumps. Thus, this pump reduces the burst or collapse concerns of the thin-walled extension couplings and allows deeper producing depths to be attained.

Technical parameter list:

.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
