Lowara Flygt NP3127.161.HT487 Cast Iron Rail Mount High-Head Sewage Pump for High-Lift Transfer with N-hydraulic

Industrial waste transport and high-lift disposal duties requiring significant vertical lift utilize the Lowara Flygt NP3127.161.HT487 for its high-head capability. This rail-mounted sewage pump is specifically engineered for semipermanent wet well installations needing reliable solids management and sustained efficiency. It provides a durable solution for infrastructure stations where consistent hydraulic pressure is critical for handling contaminated media.

Driving the unit’s hydraulic curve is a 5.9 kW motor achieving a maximum head of 22.5 m and a maximum flow rate of 2520 L/Min. Drawing a rated current of 13 Amps at 415v, the three-phase squirrel cage motor provides the torque required for managing solids-laden wastewater. Capable of continuous duty, the induction motor features high-grade insulation and efficient heat dissipation for reliable performance in demanding submerged environments.

At the heart of the pump is the Adaptive N-hydraulic system, which uses an axial self-cleaning movement of the impeller to clear solids from the hydraulic path. By ejecting debris via a specialized relief groove, the pump maintains sustained efficiency and prevents efficiency drops associated with material buildup. This capability results in lower energy consumption and significantly reduced manual intervention for cleaning during heavy-duty disposal tasks.

Mechanical protection is prioritized via a specialized Plug-in™ seal arrangement featuring corrosion-resistant cemented carbide faces to protect the internal electrical components. The physical construction utilize high-quality gray cast iron for the body and housing, offering superior structural mass and mechanical durability. Motor safety is reinforced by Class H stator insulation and thermal contacts that trigger a safety shut-off at 125°C.
