Abstract:
A progressive vortex pump having a pump assembly including an inlet valve in contact with a fluid and an outlet valve in contact with a pump pipe, the pump assembly is driven by a shaft connected to a motor assembly and includes a pump body with a variety of pump stages having a stator attached to the pump body, a diffuser attached to the front and rear of the stator, and a rotor coupled to the shaft inside the stator. Each pump stage includes at least two inlet stages in contact with a respective circular channel in contact with a respective outlet stage, the inlet and outlet stages are evenly distributed along the internal perimeter of the stator, and the pump stages are arranged such that each outlet stage of a front pump stage is connected to a respective inlet stage of a rear pump stage.
