Product Overview
Industrial pressure boosting and high-volume groundwater extraction are well served by the Lowara ZN612/11-3. This 5.5 kW radial flow pump delivers 124.7 metres of shut-off head from a 6-inch AISI 316 stainless steel wet end, with a compact 142 mm diameter that fits standard borehole casings.
The 415V three-phase motor draws 12.7 Amps and generates 275 L/Min maximum flow. Performance complies with EN ISO 9906 Grade 3B tolerances. The 65 mm discharge port accommodates standard pipework, while 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. The suction strainer limits sand ingress to 100 g/m³, and the radial flow impeller includes a removable wear ring. A replaceable coupling allows maintenance without full pump extraction.
At 63 kg, the pump features microcast stainless steel head and motor support components. Safety hook holes on the delivery port secure the unit during installation. Maximum liquid temperature is 35°C, and the pump accepts L6W motor configurations.
