Robust pump unit completely made from stainless steel suitable also for corrosive liquids. Construction made from premium components as well as standard equipped with protection devices to guarantee extended life time and high grade of reliability.


Impeller of the CAV(X) series.

For optimum adaptation to the pump medium and operating conditions.

Vortex impeller

For coarse and fibrous polluted, braid-forming and gaseous media.

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.
