Chemineer™ RL-3 Ragless Impeller

Superior Performance
The RL-3 ragless impeller is specifically engineered to prevent
fibrous material build up. This is accomplished through several key
product design features that eliminate any edges or protrusions that
would allow fibrous material to agglomerate. Some of the design
features include:
•tA sweeping leading edge on the impeller blades
•tA swept back connection to the central hub
•tWelded design or bolted design with non-protruding fasteners
•tHigh axial flow RL-3 impeller for superior mixing performance in blending
and solids suspension applications

The RL-3 ragless impeller eliminates expensive
maintenance and downtime caused by fibrous
material build up on the agitator’s impeller.
Safe and Reliable
Operation
The RL-3 impeller eliminates
the need to frequently raise the
shaft and impeller from the fluid
in order to remove the fibrous
material build up, providing
significant benefits that include:
•tIncreased safety by eliminating
frequent handling of the agitator
by maintenance personnel
•tReduction in downtime and
maintenance costs
•tElimination of fibrous material
handling and disposal
•tStrong central hub and sturdy
blades designed to handle the
loads related to material and flow
impingement to ensure reliable
operation and long service life
