Multiphase Pump
LUFKIN Don-Nan
Multiphase Pumps deliver exceptional performance in wells with high gas and sand-laden fluid by utilizing a combination of carefully selected components.
The Don-Nan Stroke-Thru Solids Pump is specially designed to provide maximum run-life in wells that produce large amounts of varying types of solids such as scale, trash, and sand.
The design of the Multiphase Pump relies on the principle features that make many of our other specialty pumps excel in their respective applications.
In order to effectively handle gas, the Multiphase Pump relies on a hollow valve rod for increased rigidity compared to a valve rod. In instances of incomplete pump fillage due to gas or sucker rod over-travel, the hollow valve rod is able to prevent buckling at the top of the pump and translate any bending that might occur farther up the rod string, distributing stress throughout the equipment and mitigating damage.
