Magnetic personality

Rotor bearings controlled by magnetic fields mean high performance without mechanical friction. With no wear, why schedule downtime for bearing overhaul?

Never wearing thin

No mechanical wear maximizes service life and minimizes maintenance costs.

Stop start

Stop and start reliably without mechanical friction or wear - ideal for varying wastewater oxygen requirements.

Dry run

With no oil required for lubrication or cooling, don’t let leaking, frozen, boiling or sour liquid affect your uptime.
