3 - 1/2" API RHA Subsurface Sucker Rod Pump For Oil Well
API RHA Subsurface Sucker Rod Pump for Oil Well
API RHA subsurface sucker rod pump description:
Sucker rod pump is suitable for reducing the time of workover for deep well as it is not necessary to pull all the tubing out of the well hole when checking the pump, which makes the operation quicker and the service life of tubing longer. The rod pump is in a state of "free hanging", so it is suitable for deviated wells.
According to seating mode, the rod pump can be divided into two types: cup hold-down and mechanical hold-down.
According to anchored position, the pump can be divided into top hold-down pumps and bottom hold-down pumps which include stationary barrel and traveling barrel types.
The space between the plunger and barrel reduces eccentric wear thus, extended the service life and guarantee improved pump efficiency.
A downhole Sucker Rod Pump is used on onshore sites to create a mechanical lifting motion. All pumps are available in both cup & mechanical hold down seating configurations.
