Researches on Design and Manufacturing of Innovative Double Gears Pumps

This paper presents the results of the researches with application in production for the innovative realization of the double gear pumps with minimum axial gauge and minimum number of parts for the increase of reliability in use and reducing the production costs. The innovative design characteristic is represented by adaptive dimensioning with minimum gauge, depending on requirements, the type of drive, the fixing method, the connections for the hydraulic circuit and intermediary sealing between stages which allows the operation with different liquid mediums.The innovative technological characteristic is on integrated adaptive system (lean production) using computer assisted manufacturing on CNC machines with minimal production time and high quality. This way of production of double gear pumps is obtaining significant reductions in the cost of manufacturing and much smaller gauges the double pump available on the market.
