In order to promote heavy oil recovery and solve the conventional plunger pump problems, which include wear, large leakage, and a stuck pump in the process of heavy oil production, this paper reports on the research and development of a new pump, and promotes its application in heavy oil recovery. With the use of the new pump, an advanced level of no leakage in a deep well with heavy oil is achieved and it is shown that the pump remarkably improves the pump volumetric efficiency.
