Bottom Anchor Way Well Pump Tubing API 11AX TH

API 11AX TH Bottom Anchor Way Well Tubing Pump

API 11AX TH bottom anchor way well tubing pump description:

Tubing pumps are so named because the working barrel of this pump is coupled with the production-tubing string.

The pump barrel assembly of the tubing pump connected on the tubing string,and with its down to the bottom of the well.Plunger assembly connected on the sucker rod string and with it down to the pump barrel position in the well,then with it do up and down reciprocating motion, so as to realize the production process.

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.

Features:

1.The standing valve at the bottom of the pump is apt to immerse in the well fluid, therefore, it is applicable to the well with low fluid level

2.Because the pump barrel can only bear the external hydrostatic pressure rather than the tension load caused by the fluid column weight, there is little change in plunger clearance. This makes the pump suitable for deep wells.
