YCB圆弧齿轮泵主要有齿轮、轴、泵体、安全阀、轴端密封所组成。齿轮经热处理有较高的硬度和强度，与轴一同安装在可更换的轴套内运转。泵内全部零件的润滑均在泵工作时利用输出介质而自动达到。
泵设有安全阀作为超载保护，安全阀的全回流压力为泵额定排除压力的1.5倍，也可在允许排出压力范围内根据实际需要另外调整。但注意本安全阀不能作减压阀的长期工作，需要时可在管路上另行安装。
从主轴外伸端向泵看，为顺时针旋转。
YCB圆弧齿轮泵比普通齿轮泵使用寿命长2-3倍，主要区别在于圆弧齿轮泵的齿轮为圆弧型，泵在运转过程中齿轮和齿根咬合是处于两个圆弧平滑过渡，没有任何死点或卡住现象；所以使用寿命极长。而普通齿轮泵齿型是渐开线斜齿轮，泵在正常运转过程中齿轮和齿根转动时齿轮齿顶菱角会和与之相配合的齿轮齿根产生碰撞、磨损、齿轮齿根部位也会产生困液，致使渐开线齿轮泵存在转动时噪音比较大的现象，而且齿轮泵的使用寿命会受到影响。
YCB圆弧齿轮泵齿轮采用双圆弧正弦曲线齿型。YCB圆弧齿轮泵与渐开线齿轮相比，优点是齿轮啮合过程中齿廓面没有相对滑动，所以齿面无磨损，运转平衡，无困液现象、噪声低、寿命长、效率高。该泵摆脱了传统设计的束缚，使得齿轮泵在设计，生产和使用上进入了一个新的领域。
