1. Centrifugal pumps are used to transport fluids by converting rotational kinetic energy into fluid kinetic energy of fluid flow. Rotational energy usually comes from an engine or electric motor. They are a subclass of dynamic axisymmetric energy-absorbing turbines. The fluid enters the pump impeller along or near the axis of rotation and is accelerated by the impeller, flows radially outward into the diffuser or volute chamber (housing), and then exits from it. Common uses include water, sewage, agriculture, oil and petrochemical pumping.

2, axial flow pump by rotating impeller blade on the liquid generated by the force of the liquid along the axis of the pump, there are vertical, horizontal, inclined and tubular several kinds.

3, mixed flow pump is a kind of pump between centrifugal pump and axial flow pump. The specific speed of the mixed flow pump is higher than that of the centrifugal pump and lower than that of the axial flow pump, generally between 300-500. Its head is higher than the axial flow pump, but the flow is smaller than the axial flow pump and larger than the centrifugal pump. Used to transport clean and contaminated media, chemically neutral or aggressive media. Forced circulation in chemical processes, mariculture, urban gas engineering, water treatment systems
