GKV 60 Hz
Construction
Submersible pumps with vortex impeller.
The impeller offers reliability against clogging due to the feature of wide through
passages, and a good resistance to wear thanks to the absence of shimming.
The versatility of use compensates for this impellers somewhat lower efficiency.
The impeller can be reduced in dimension to offer different characteristics.
Delivery port DN 65-80-100.
Applications
For waste water and sewage with suspended bodies and with the presence of
filamentous bodies, they are particularly suitable for the emptying of wells or
primary collection tanks and septic tanks in domestic, residential and industrial
installations.
