Impeller trimming is a proper way to alter the performance of centrifugal pump with a constant speed so as to meet the demand on the specified flow rate and head in pumping systems. The affinity law accounting for the impeller trimming is the key relation to determine the pump performance with a trimmed impeller. There seems no experimental study dealing with such an affinity law for centrifuga...

Abstract It is well-known that one of the reasons for reducing head a centrifugal pump, when trimming its impeller, reduction slip factor. There are various methods used to determine it, but there lack information on whether they applicable in case pump with trimmed impeller operates. In present work, comparative experimental study concerning applicability some factor, two pumps different speci...

The pumping capacity is the maximum flow rate through a pump at its design capacity. In process of water and other fluids, required to accurately size systems, determine friction head losses, construct system curve select motor. Failure choose right for system, improper installation operation results into higher consumption energy. insufficient affects plant’s operations such as maintenance cos...

Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...

Major industrial sector are using, most pumps are of centrifugal type. Centrifugal pumps are widely used because of their design simplicity, high efficiency & low maintenance. Modern centrifugal pumps are not complex machines. Despite the simplicity of design and production, centrifugal pumps are still capable of posing complex puzzles during their operation. The performance of a pump must be m...
