He has made significant contributions to the field of pump technology, particularly in the design of centrifugal pumps. With a total of 2 patents to his name, Letov's innovations focus on enhancing the efficiency and longevity of pumps used for handling abrasive liquids.
Latest Patents
Letov's latest patents include a "Seal means for a centrifugal pump" and a "Centrifugal pump." The first patent describes a pump designed to handle liquids laden with abrasive particles. It features a unique sealing mechanism that utilizes at least two floating rings positioned on the shaft within a circular gap. This design allows for effective sealing between the low- and high-pressure stages of the pump. The casing includes a circular collar that partially covers the gap, ensuring that the rings maintain contact during operation.
The second patent, the "Centrifugal pump," presents an innovative approach to impeller arrangement. This design incorporates impellers that are arranged in a counter-opposed manner on the pump shaft. The shaft features tapered surfaces at the points of impeller mounting, which face each other. This configuration, along with a movable bushing, allows for better pressing of the impellers against the tapered surfaces, significantly extending the service life of the pump.
