The necessary aspects regarding the composition, operating principle, features and calculation of the new gear pump are provided. Excellent performances of the new pump are respresented by its balanced radial pressure on the drive shaft, double displacement and longer service life of the pump. The proposed new pump offer innovative ideas for upgrading the classical gear pumps. ER -
