This paper present the characterization of the driving unit of a rodless mechanical pumping device, named linear Mechanical Submerged Pumping of double effect (MSP) which is the subject of a recent patent application at the National Institute of Intellectual Property (BR 2013 10 7033422). This rodless pumping device consists of an alternative hydraulic piston adapted to operate partially or totally submerged in oil production wells. The device is also a viable alternative for pumping water from deep aquifers. The goal of this work is to characterize and identify the main components used in the MSP concept, using the operating parameters and dimensions of conventional artificial lift wells, available in the Laboratory of Artificial Elevation of the Federal University of Bahia (LEA/UFBA). Our results allow estimating the characteristics of the components required to meet the requeriments for production considering the operating parameters of MSP. This new method of artificial lift and the alternative method of pumping fluid of linear wells or with deviation, justify investment in the production of specific components as well as producing the prototype, testing and validating the apparatus using trading components.
