Submersible motor pump with internal grinding device for both fixed and mobile installation in wet environments. The pump can operate in both intermittent and continuous modes. The motor is adapted for three-phase current and is surface-cooled by the surrounding environment. Between the motor and the hydraulics, there is a sealing chamber filled with medical white oil, preventing the ingress of media into the motor. It can be used for wastewater with faeces according to the EN 12050-1 standard (including long fibres), as well as for pre-treated wastewater without faeces or sewage water.
