Product benefits:

• Self-centring seating in the discharge tube, sealed by an O-ring, for quick installation and removal.
• Slim motor design reduces discharge tube flow losses.
• High reliability due to comprehensive monitoring: bearing temperature, vibration sensor, thermal motor protection, leakage sensors in the motor and connection spaces, and mechanical seal system leakage monitoring.
• Low-vibration hydraulic system with inlet ribs and an optimized bellmouth for vortex-free inflow.
• Absolutely water-tight resin-sealed cable entries prevent water ingress into the motor, even if the cable is damaged.
