Single-stage horizontal centrifugal pump completes the liquid transportation by the centrifugal force generated by the impeller of the rotary pump. Its pump body and motor are composed of main shaft, Impeller, pump case and mechanical seal and connected by coupling. They are mainly used for heating, cooling towers, air-conditioning systems and can be used as booster pumps in water supply systems. The pull-back structure of axial inlet and radial outlet ensures a more compact pump structure and pipeline.
