Lowara Flygt NP3102.160.SH256 Cast Iron Rail Mount Sewage Pump for Stormwater Management with N-hydraulic

Civil engineering projects and infrastructure dewatering stations utilize the Lowara Flygt NP3102.160-SH256 for its specialized high-lift transport capability. This rail-mounted unit is built for steady evacuation duties in semipermanent wet well installations requiring large-volume liquid displacement against substantial vertical elevation. Its robust design facilitates continuous operation during challenging industrial disposal cycles and heavy-duty storm water management tasks where reliability is a critical priority.

Hydraulic energy is generated by a 4.2 kW induction motor operating at 415v, achieving a maximum head of 22.5 m and a maximum flow rate of 1500 L/Min. Drawing a rated current of 8.2 Amps, the three-phase squirrel cage motor provides the torque required for managing solids-heavy media. The motor's IP68 encapsulation allows for continuous immersion up to 20 meters, providing stability even in flooded wet well conditions during peak inflow events.

Operational uptime is maintained by the Adaptive N-hydraulic system, which clearing debris dynamically through an axial movement during rotation. The impeller configuration works in conjunction with a relief groove to clear solids away from the vanes, preventing the clogs and efficiency drops common in standard hydraulic designs. This self-cleaning action ensures that energy consumption remains optimized during high-volume pumping duty without requiring frequent manual clearing interventions.

Physical build features high-density gray cast iron (GJL-250) for the pump body and housing, ensuring excellent thermal dissipation and structural strength under high-pressure duty. Sealing is managed by a dual mechanical Plug-in™ system with corrosion-resistant cemented carbide faces to protect the internal electrical assembly. The stator is safeguarded by Class H insulation (180°C) and winding-embedded thermal contacts that provide an automatic safety shut-off if internal temperatures reach 125°C.
