Cup Seating RHAC Downhole Pump With Heavy Wall Barrel

Heavy wall barrel cup seating RHAC downhole pump description:

Downhole rod pump is also known as insert rod pump, it is one type of the conventional sucker rod pumps. The downhole rod pump is connected to the sucker rod directly, downhole pump can be pulled out with sucker rod and does not influence the tubing, so the well inspection and workover is more convenient. It can save a half times and reduce cost of the pumping test, thus the rod pump is suitable for the deeper well.

Downhole pump has 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.

Downhole pump bore sizes range from 1” to 4 ¾” diameter with mechanical, cup type (chevrons) or friction type hold downs available in a variety of materials to suit specific well conditions.

Features:

To achieve maximum performance,API subsurface pumps are machined with extra small clearance between the plunger and the inside wall of the barrel.
