Abstract
A pump is provided within a vortex generator having a plurality of equally spaced blades which rotate in a pump casing to form a nucleus of fluid in the shape of an ellipsoid having an upper tapered end and a lower tapered end with a thicker central section at the blades. Fluid flows in a synchronized flow from the lowered tapered end of the nucleus in a rotating vortex column of fluid which initially flows out of the pump inlet to swirl the ambient fluid about the inlet and causes a low pressure area and a swirling of the ambient fluid to flow inwardly through the pump inlet in a direction counter to the vortex column flow. A belt of fluid rotates between the nucleus and the pump casing. The blades are curved to retain fluid in the nucleus and momentum energy is cumulatively applied to keep the swirling column of fluid swirling through the pump outlet. A tapered section on the pump between the pump inlet and pump outlet assists in flow therebetween. A divider may be provided in the pump casing with an opening in the divider to allow the vortex column to flow from a vortex generating chamber to a pump discharge chamber while debris hits the divider and is prevented from flowing into contact with the blades. Pressure boosters may be added to the blades.
