Impeller
Impeller of the AK(X) series.
For optimum adaptation to the pump medium and operating conditions.
Enclosed multi-channel impeller
For dirty and muddy fluids with solids.
The network frequency is 50 Hz in the EU.
In other parts of the world, such as in the North American region, Brazil, Saudi Arabia or South Korea 60 Hz.
HOMA pumps are available for both frequency ranges. A selection of the pumps for the valid frequency range at the installation site must be made accordingly. We are happy to assist you in the selection of the right pumps.
At this point, you exit the HOMA website and are directed to the website offering our pump selection software HOP.Sel.
