Wear in centrifugal pumps with causes, effects and remedies: A Review

Abstract

Pumps are widely used machinery in various applications. Mostly now, a day in importance is seen from household applications to different industrial level. Various types of pumps are available in the market according to their applications and centrifugal pumps are one of most common types among them. In the course of time, pumps faces various problems and repairing is required. Among them wear is one of the most common problem for reduction in pump performance. Cavitation, corrosion, erosion, fatigue are the common wear mechanisms faced by the centrifugal pumps. In order to minimize such problems frequent maintenance strategies are required. Various researchers have purposed different methodologies. Material properties, coatings in design and optimizing hydraulic and mechanical design for such challenges has been now a major topic of research. In this study, the different wear mechanisms and their causes with reference to various research paper is presented. Different effects for such problems is highlighted. Finally, new emerging technology developed by various researchers for minimizing such wear challenges are discussed.
