Blade pump: It relies on rotating blades to transfer mechanical energy to the fluid. Common types include centrifugal pumps, axial flow pumps, and mixed flow pumps. Among them, the working principle of the centrifugal pump is: under the action of the centrifugal force generated by the high-speed rotation of the impeller, the liquid is thrown outward and pressed into the volute, forming a vacuum, so that the water in the pool is sucked in through the suction pipe under the action of external atmospheric pressure, thus continuously sucking water and pressurizing; the axial flow pump uses the thrust generated by the high-speed rotation of the impeller to raise the water level; the working principle of the mixed flow pump combines centrifugal force and lift.

Volumetric pump: It utilizes the periodic change in the volume of the working chamber to transfer energy, thereby achieving fluid transport.
Vane pump: It relies on rotating vanes to transfer mechanical energy to the fluid. Common types include centrifugal pumps, axial flow pumps, and mixed flow pumps. The working principle of a centrifugal pump is: Under the action of the centrifugal force generated by the high-speed rotation of the impeller, the liquid is thrown outward and pressed into the volute casing, forming a vacuum, causing the water in the pool to be sucked in through the suction pipe under the action of external atmospheric pressure, thus continuously sucking water and pressurizing; the axial flow pump uses the thrust generated by the high-speed rotation of the impeller to raise the water level; the mixed flow pump's working principle combines centrifugal force and lift.
