Good for volatile and explosive fluids because the close clearance wear rings are the parts that will contact if the shaft displaces from its centerline You would have to use soft, materials for the impeller and that is not very practical. The impeller is initially very efficient, but looses its efficiency as the wear ring clearance increases Efficiency can be maintained through impeller clearance adjustment. No impeller adjustment is possible. Once the wear ring clearances doubles they have to be replaced. This means the pump had to be disassembled just to check the status of the wear rings. The impeller can be adjusted to compensate for wear and stay close to its best efficiency. No pump disassembly is necessary.
