Abstract A new flat valve type radial piston pump for heavy oil transportation is introduced in the article.This new radial piston pump uses many independent shakeable cylinder blocks besides mechanical mandatory return stroke.Compared to the traditional reciprocating pumps,it is more compacter in frame,smaller in size,lighter in weight and lower in flow capacity pulsation rate,and so on.In accordance with the standard testing of GB/T 7784—2006,under the rated working condition,the pump mechanical efficiency is extended to 89% while the pump volumetric efficiency is extended to 92%.Besides,a reliability test which lasted three months was done for a prototype of this new pump in Liaohe oil region.During this test,the prototype ran smoothly with no malfunction and no leakage.So this new pump has good application prospects as a kind of energy-saving product.

Key words： radial piston pump heavy oil transportation flat valve independent shakeable cylinder block mandatory return stroke
