Vertical multistage surface centrifugal water pump is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor. The motor output shaft directly connects with the pump shaft through a coupling. The pressure-resistant cylinder and flow passage components are fixed between pump head and in-and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload. Vertical multistage surface water centrifugal pump, attached with long shaft electric motor. Compact structure renders small size of pump; axial inlet and radial outlet. Vertical multistage surface water centrifugal pump transmission medium: 1, Non flammable and explosive medium, thin, clean, containing no solid particles or fibers. 2, such as mineral water, softened water, pure…
