美国尼科NICO进口小流量三螺杆泵适于输送燃料油、润滑油、液压油或其它润滑性液体，所输介质中不得含有磨料颗粒和对泵材料有腐蚀的物质，否则会影响小流量三螺杆泵的使用寿命。小流量三螺杆泵泵本身仅三根螺杆组成，但有多种结构形成，一般小流量，0.2-6.5m3/h泵的泵体和衬套合为一个卧式安装，轴封为机械密封。中等流量以上的泵衬套为一单独的零件固定于泵体内。大流量泵多制成双吸结构。轴封根据输送的介质不同选择合适的机械密封。船用泵的原动机为交流船用电机。小流量三螺杆泵利用螺杆的回转来吸排液体的。在三螺杆泵中，中间螺杆为主动螺杆，两边的螺杆为从动螺杆。在主动螺杆由原动机带动回转的同时，从动螺杆也随之而进行反向旋转。在螺杆泵中，主、从动螺杆的螺纹均为双头螺纹。小流量三螺杆泵和离心泵相比螺杆泵无需安装阀们流量是稳定的线性流动；与柱塞泵相比之下，螺杆泵具有_的自吸能力与吸入高度；对于各种混合杂质含有气体及固体颗粒或纤维的介质与各种腐蚀性物质螺杆泵比隔膜泵更加适宜；螺杆泵还可用于药剂填充和计量。
