Assessment of the Life Cycle Cost and Improvement of the Parametric Series of Torque-Flow Pumps

The research developed and proposed criteria for a comprehensive assessment of the life cycle cost of a dynamic pump installation, which allows to practically and visually assess the value of energy efficiency (energy consumption indicator εeff) and mass-dimensional qualities (material capacity indicator εmat) of dynamic pumps. The practical application of the developed indicators made it possible to evaluate the value of energy efficiency and mass-dimensional qualities of the existing parametric series of TFP torque-flow pumps. It was determined that many torque-flow pumps significantly exceeded average energy consumption and material capacity indicators. An updated promising torque-flow pump TFP 25-28-2900 was developed. The energy efficiency of this pump at BEP mode is 0.4578. The design of the promising TFP 25-28-2900 pump made it possible to reduce the energy consumption indicator εeff up to 51.2% and the material capacity indicator εmat up to 74.6%. The research results correspond to the guidelines approved by the United Nations as Sustainable Development Goals, i.e., clean water and sanitation, affordable and clean energy, and industry, innovation and infrastructure.
