The integrated motor protection circuit breaker, capacitor (in 1-phase versions) and temperature sensor in the motor windings protect the motor and facilitate an automatic restart function. Clog-free continuous operation for pumped media with solid substance constituents is ensured thanks to the large inlet opening and the non-clog impeller. The robust, rust-free stainless steel shaft with double-row angular ball bearings provides vibration-free running and thus a long pump life. Even under exceptional operating conditions effective sealing and a high degree of reliability is guaranteed thanks to the double mechanical face seal in an oil bath (primary seal: silicon carbide on silicon carbide).
