Two-Stage Hollow Valve Rod Pump
Sucker rod pump for reduced gas interference
The versatile two-stage hollow valve rod pump improves production in a variety of applications, especially those where gas interference is an issue.
This pump uses an oversized standing valve for maximum compression ratio. Additionally, the use of a secondary traveling valve atop the assembly holds the weight of the fluid column in the tubing so that the lower traveling valve can more easily open, reducing gas interference.
Applications
Wells with moderate gas and solids
Benefits
Increased rigidity in traveling assembly and improved gas handling
Features
Double traveling, oversized standing, and hollow valve rod with high compression ratio
Address common problems such as rodstring wear and damage caused by gas interference, erosion, or insufficient fluid levels.
