– vanes are mounted on a backing plate called a “shroud”

– minimal backing plate

ADVANTAGES

– more efficient than Open Impeller due to less recirculation

and more defined fluid pathways

– can handle more solids than the Closed Impeller

DISADVANTAGES

– not as efficient as the Closed Impeller

– can handle less solids than the Open Impeller 

** Many of Forte Fluid Systems Centrifugal Pumps are a combination of multiple Centrifugal Pump types. For example and End Suction Pump (Between Bearing) that has a Closed Impeller. **
