Large-scale irrigation and groundwater supply operations depend on the Lowara ZN612/8-3, a 4 kW radial flow pump delivering 90.7 metres of head from a 6-inch AISI 316 stainless steel wet end. Its 142 mm outer diameter fits standard boreholes, and the robust construction handles continuous operation in demanding agricultural and industrial applications.
The 415V three-phase motor draws 9.89 Amps and achieves 275 L/Min maximum flow. Performance complies with EN ISO 9906 Grade 3B standards. The 65 mm discharge port connects to standard pipework, and the integrated non-return valve prevents backflow when the motor stops.
AISI 316 stainless steel throughout the wetted end provides corrosion resistance against aggressive groundwater, while the suction strainer limits sand ingress to 100 g/m3. The radial flow impeller features a removable wear ring, and the replaceable coupling simplifies maintenance without pump removal.
Weighing 57 kg, the pump includes microcast stainless steel head and motor support castings. Safety hook holes on the discharge head facilitate secure lowering. Liquid temperature tolerance is 60°C, and the unit accepts L6W motor configurations.
