This paper describes the design and performance of external gear pumps. We have a method developed to calculate accurately the displacement volume of external gear pumps having a non-involute tooth profile and an involute tooth profile. Using this method, the displacement volumes of external gear pumps with an involute tooth profile, a cycloid tooth profile, an involute-cycloid composite tooth profile, a modified cycloid tooth profile and an asymmetric tooth profile are calculated. Then, the merits and the demerits of these tooth profiles are discussed with respect to the displacement volume. In addition, the gear pumps having some external tooth profiles were designed and manufactured, and the displacement volume of the gear pumps was measured. Consequently, it was confirmed from both the calculated and the experimental results that the displacement volume of the external gear pumps with the non-involute tooth profiles is larger than that of the involute tooth profile.
