YCB圆弧齿轮泵主要由齿轮、轴、泵体、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。
YCB圆弧齿轮泵设有阀作为超载保护，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。但注意本阀不能作减压阀的长期工作，需要时可在管路上另行安装。
YCB圆弧齿轮泵适用于输送不含固体颗粒和纤维，无腐蚀性，温度不高于80℃，粘度为5×10-6～1.5×10-3m2/s (5-1500cSt)的润滑油或性质类似润滑油的其它液体。
YCB圆弧齿轮泵应用范围：
在输油系统中可用作传输、增压泵；
在燃油系统中可用作输送、加压、喷射的燃油泵；
在液压传动系统中可用作提供液压动力的液压泵；
在工业中，均可作润滑油泵用；
YCB圆弧齿轮泵要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泵为圆弧型，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，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。
