Semi-open impeller – 4H; Reinforced impeller – 4W
Tapflo CT pumps can be fitted with a semi-open impeller in comparison to
its standard open impeller. This option ensures more stable operation, lower
noise, lower vibrations and more robust construction. It is recommended to
use the semi-open impeller when hard solids can be present in the pumped
liquid. This impeller is always in reinforced execution.
The reinforced impeller is a great option when pumping high viscous
liquids or ones containing solid particles. This design is much more robust
and can withstand more tensions transferred from the liquid.
NOTE! The D, F and G size impellers are reinforced as standard.
