Standard centrifugal pumps need the impellers to be fully submerged in order to pump correctly If air is encountered the pump can become air bound which makes it much harder to pump the water through the impellers In order to fix situations when the pump encounters air and causes the pump to become stuck you need a special type of pump The CRE-Plus is a simplex pump system and one of a wide range of E-pumps offered by Grundfos It utilizes smart pump technology to vary motor output according to demand so energy is not wasted on generating pump speed that is not required Literature - CRE Brochure - CRE Product Guide

What happens when a centrifugal pump runs dry?

Pumps should not be operated running dry When a pump is run dry there are two common results 1) The impeller will melt along the shaft causing the impeller to seize onto the shaft If the impeller seizes it will stop and not rotate To correc
