MIXED FLOW CENTRIFUGAL PUMP

The patent holder is willing to grant license to Companies to develop pump systems to meet their market requirements.

This recently patented Mixed Flow Centrifugal pump introduces several new inventive concepts. These concepts deliver greater pumping efficiency and production cost efficiency to the pump industry. It increases pump design options and combinations of construction materials. The design principally utilises the benefits of a specially engineered sinusoidal impeller within a toroid shaped pump chamber that closely mirrors the concave rotating profile of the sinusoidal impeller. This facilitates the use of double acting aqua plane technology to ensure ultra-smooth, reduced turbulence and interference, pumping efficiency and power. The pump is fed by a double intake suction system which counter-balances the high speed rotating impeller. This revolutionary invention has US and GB Patents. The invention is in the pre-production phase, which has shown great potential and promises to transform pump design options. This mixed flow centrifugal pump design is being unveiled to the pumping world with the introduction of several inventive concepts. It holds the promise to deliver greater efficiency, pressure and economy to the pump industry. It principally utilised the benefits of a specially engineered sinusoidal impeller within a toroid shaped pump chamber that closely mirrors the concave rotating profile of the sinusoidal impeller. This facilitates the use of double acting aqua plane technology to ensure ultra-smooth, reduced turbulence and interference pumping efficiency and power. The pump is fed by a double intake suction system which counter-balances the high speed rotating impeller. The out flow BENEFITS FROM PROPORTIONALLY variable discharge from both sides of the impeller resulting in a very low impulse index. The position of the double intake system in relation to the single outflow system allows for maximum momentum transfer to the fluids before exiting the low profile outlet at high velocity. Key to the design is the specially crafted impeller, which facilitates smooth and maximum power transfer from motor to fluid. The impeller enables mixed flow operations. Its shape is crafted to occupy as little space as possible yet giving a high power to weight ratio. The shape of the impeller virtually eliminates turbulence and interference amongst the currents created by the vanes OF CONVENTIONAL DESIGNS. The impeller and casing can be made from a variety of materials thereby increasing the different types of fluids that can be pumped. The design also maintains a high degree of equilibrium, resulting in increased energy saving, efficiency, less vibration and quieter operation. The casing and bearing setup allows near perfect balance and rotating efficiency.

Technical Aim.

The technical approach of this pump design is aimed at finding ways to optimizing the efficiency of pumping systems which can result in significant energy and cost savings as well as reduced carbon dioxide emissions.

The pump is fed by a double intake system which counter-balances the high speed rotating impeller. The position of the double intake system in relation to the single outflow system allows for maximum momentum transfer to the fluids before exiting the low profile outlet at high velocity. Key to the design is the specially crafted impeller, which facilitates smooth and maximum power transfer from motor to fluid. The impeller enables mixed flow operations. Its shape is crafted to occupy as little space as possible yet giving a high power to weight ratio. The shape of the impeller virtually eliminates turbulence and interference amongst the currents created by the vanes of conventional designs. The impeller uses both sides of the blade to transfer kinetic energy to the fluid.

The impeller and casing can be made from a variety of materials thereby increasing the different types of fluids that can be pumped. The design also maintains a high degree of equilibrium, resulting in increased energy saving, efficiency, less vibration, reduced shaft deflection, and quieter operation. The casing and bearing setup allows near perfect balance and rotating efficiency. The key components can be either pressed or 3D printed from top quality materials thereby increasing ease of manufacturing. The manufacturing process is flexible to meet the requirement of varying customer demands.
