Centrifugal pumps are widely used in various industries for their efficiency and reliability in moving liquids. However, one common issue that centrifugal pumps face is their inability to handle air or vapor effectively. This limitation can lead to reduced performance, increased energy consumption, and potential damage to the pump system. In this article, we will explore the reasons why centrifugal pumps struggle with air and vapor, the importance of priming, and common troubleshooting methods to address these challenges.
A centrifugal pump cannot pump a gas; therefore, the differential pressure necessary for flow will not be created if the impeller is having air or vapour. Prior to start-up, the pump’s Casing should be filled with liquid and vented of all gases. The pump can be connected through vents to a central priming system. See more
Efficiency of Centrifugal Pumps
Efficiency is a crucial factor in the performance of centrifugal pumps. Unlike positive displacement pumps, where efficiency increases with pressure, centrifugal pumps operate differently. The efficiency of a centrifugal pump peaks at a specific flow rate and head, making it essential to operate within these parameters for optimal performance. When air or vapor enters the pump system, it disrupts the flow of liquid and causes inefficiencies in the pump operation.
Why Centrifugal Pumps Cannot Handle Air
One of the primary reasons centrifugal pumps struggle with air or vapor is their design. Centrifugal pumps rely on the principle of centrifugal force to move liquid through the pump casing and discharge it at a higher pressure. When air or vapor is present in the pump system, it creates pockets of trapped gas that disrupt the flow of liquid. This phenomenon, known as cavitation, can lead to reduced pump efficiency, increased noise levels, and potential damage to the impeller and other pump components.
Importance of Priming in Centrifugal Pumps
Priming is a critical step in preparing a centrifugal pump for operation. Priming involves filling the pump casing and suction pipe with liquid to remove any air pockets and create a continuous flow of liquid through the pump. Without proper priming, centrifugal pumps may struggle to overcome the air resistance and achieve the desired flow rate and pressure. Priming ensures that the pump operates efficiently and prevents issues such as cavitation and air binding.
Troubleshooting Air-Related Issues in Centrifugal Pumps
Efficiency – In positive displacement pumps, efficiency increases with increasing pressure. Whereas in non-positive displacement pumps, efficiency peaks at best
