An integrated axial flow pump based on electromagnetic piston radial drive comprises an impeller, a guide vane body, fairings, a coil, a bearing and cranks. A main shaft (17) of the pump is directly connected with the crank (15), the crank (25) is arranged in the middle triangular prism type fairing (11), the crank (25) is connected with a connecting rod (12), and the connecting rod (12) penetrates a hollow part of the guide vane body (27). A magnetic piston (8) in an outer piston cylinder (9) is connected, and an electromagnetic piston device is placed outside a completely-sealed pump shell (29). A water inlet horn (30) is arranged in front of an impeller shell (19), the guide vane body (27) is fixed to a pump body (29) and supports the main shaft triangular prism fairing (26), and the main shaft triangular prism fairing (26) supports the main shaft (17) through a rear bearing set (4) and a front bearing set (16).
