A pump cannot be deemed to be “efficient” if it is not pumping its intended level of flow. When a centrifugal pump is not pumping enough liquid, the impediment is usually due to issues relating to the impeller within. This article attempts to briefly describe the four major causes of low flow in pumps.             The first major cause of low flow in a pump relates to having too much clearance. “If clearances are too wide for the type of fluid pumped, excessive slip will occu

An integral component to a centrifugal pump’s functionality is its impeller. Without an impeller, centrifugal force cannot be generated upon the entering liquid. Thus, without an impeller, a centrifugal pump cannot function at all whatsoever. For this reason, proper care is necessary for a pump’s impeller so as to prevent pump downtimes and ensure maximum length of a pump’s continual operation. Damaged impellers can also lead to  low flow in pumps . The top 3 most common caus
