目前宏兴泵阀的油泵产品系列包括：3G通用型、3GR螺杆型、3GW高温加热燃油泵型，根据用户提供的温度以及流量、压力进行选择适合的产品，宏兴三螺杆泵，平稳传动完美输送。
3GC船用型及特殊型。三螺杆泵是转子式窖泵，由于主动螺杆与从动螺杆上螺旋槽相互啮合及它们与衬套三孔内表面的配合，得以在三螺杆泵的进出口之间形成数级动密封腔室，这些动密封腔室将不断把液体由泵进口轴向移动到泵出口，并使所输送液体逐渐升压，从而形成一个连续，平稳，轴向移动的压力液体。
三螺杆泵所输液体为各种不含固体颗粒，无腐蚀性油类及类似油的润滑性液体，所输液体粘度为1.2~100OE(3.0~760cst),含高粘度液体亦可通过加温降粘后输送.流量范围:0.2~590m3/h最高工作压力100bar,最高温度150℃
