Computer assisted analysis has been used extensively to optimize the pump structure and vital parts with respect to weight, strength and life. Interactive computer programs for replacing paper based documentation and service manuals have also been developed.IntroductionThe Hex mud pump is a new axial piston pump with six vertical pistons driven by two AC motors via a gear and a specially profiled cam. In contrast to crankshaft-driven triplex pumps, the Hex pump delivers a nearly pulsation free flow. Consequently, vibration problems and the need for pulsation dampeners are minimized. Other major advantages are compactness (redused weight and footprint) and no need for exchanging liner sizes. The 1500 HP version with 4" liners has a maximum rated pressure of 7500 PSI and a flow capacity of 817 GPM.The paper also includes results from the extensive prototype testing carried out recently at Rogaland Research in Norway.DefinitionsMWD = Measurement While DrillingSPM = Stroke Per MinuteGPM = Gallon per minuteHP = Horse PowerAC = AsynchronousFrom idea to a productThe goal with the development process for the Hex Pump was to produce and test only one prototype, and then have a product ready for the market. In order to obtain this, the development process was integrated together with several other related disciplines at the same time. Documentation, marketing and testing activities have also been simultaneously carried out during the development project.
