Irrigation systems and industrial water supply networks rely on the Lowara ZN612/9-3, a 5.5 kW radial flow pump delivering 102.1 metres of head. Its 6-inch AISI 316 stainless steel wet end provides corrosion resistance for continuous operation in demanding borehole conditions, with a compact 142 mm diameter that fits standard casings.
The 415V three-phase motor draws 12.7 Amps and generates 275 L/Min maximum flow. Hydraulic performance complies with EN ISO 9906 Grade 3B tolerances. The 65 mm discharge port accommodates standard pipework, while the integrated non-return valve prevents water column backflow.
AISI 316 stainless steel construction provides resistance to corrosion and abrasive sand. The suction strainer limits sand ingress to 100 g/m3, and the radial flow impeller includes a removable wear ring. The replaceable coupling allows maintenance without full pump extraction.
At 61 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 60°C, and the pump accepts L6W motor configurations.
