The company has been developed large pump since 1960, and has formed a series of large and multi-variety pumps, including ZLB/Q, ZWB/Q, ZXB/ Q-type vertical, horizontal and oblique semi-regulating/fully regulating axial flow pump and HLB/Q vertical guide vane semi-regulating/fully regulating mixed-flow pump. Accumulatively It has produced and sold more than 700 sets of large pumps, including over 500 sets of vertical axial flow pumps, over 150 sets of oblique and horizontal axial flow pumps (including shaft-well tubular pumps) and over 50 sets of guide vane mixed-flow pump.

It is mainly used for regional water transfer such as the South-to-North Water Diversion Project; urban flood control and drainage project; large-scale agricultural irrigation project; dock drainage, water level control of canal locks, and large-scale circulating water delivery of power plants.
