Closed Impeller Submersible Centrifugal Pump

Basic Differences Between Open and Closed Impellers in

In an open impeller, no pump disassembling is necessary. An open impeller is less likely to get clogged and even if it does, it is easier to clean whereas in a closed impeller, if stringy material or solids are pumped, the impeller can clog and it becomes really difficult to clean them.
