Key Features: High Power: 10 HP (∼7.5 kW) motor, rated for 400V (3-phase) systems for sustained high-head performance. Grinder System: Macerates fibers and suspended solids, significantly reducing the risk of clogging in long delivery mains. Construction: Heavy cast-iron pump body and impeller for maximum durability in harsh sewage environments. Sealing: Double mechanical seals in an oil-bath (silicon carbide on pump side) for superior, long-life leak protection. Protection: IP68/IPX8-rated submersible protection, with maximum immersion depth up to 20 m. Discharge: Flanged DN65/DN50 discharge options for secure piping. Applications: Sewage lift stations, industrial effluent, septic systems, and any high-lift installation requiring reliable solids handling.
