Abstract

The present disclosure relates to an impeller (10), wherein the impeller is manufactured in two parts by machining to increase efficiency of centrifugal pumps, minimize friction losses and facilitate periodic inspections against potential risks of failure, wear and corrosion. The key benefit of the impeller (10) is the precision of the surface quality and minimization of friction losses achieved through the machining method, which is more precise compared to casting processes. With more precise surface quality, friction losses of the impeller (10) are minimized. This ensures maximum efficiency output from the pump. Another key benefit of the impeller (10) is that the housing (20) and vanes (40) are separately produced and assembled by means of a connection element (50).
