Red Polymer Impeller B15127 for 2/1.5B-AH Slurry Pump

Enclosed Impeller

The enclosed impeller, also known as a shrouded impeller, has a circular plate on each side. It is ideal for pumping water and other liquids at higher pressures. While the enclosed design is initially very efficient, its efficiency decreases as the wear ring clearance increases. The design of this impeller makes it more difficult to modify and difficult to inspect for defects because its internal parts are hidden.

 Open Impeller

Open impellers have blades attached to a hub. This design looks very similar to a marine propeller or fan. They are ideal for situations where the impeller needs to be cleaned regularly or where there is a risk of clogging. Although open impellers tend to be less efficient, their efficiency can be maintained regularly by adjusting the impeller clearance.

Semi-Open Impeller The

semi-open impeller has a circular plate mounted on one side of the blade. It is ideal for liquids containing trash and debris.
