Product Overview
Industrial pressure boosting, groundwater lowering, and fountain waterworks rely on the Lowara 4ZN612/12-3. This 7.5 kW radial flow pump delivers 136.1 metres of head from a 6-inch AISI 316 stainless steel wet end, engineered for continuous operation in abrasive borehole conditions. The 142 mm maximum diameter fits standard well casings.
The 415V three-phase motor draws 18.7 Amps and achieves 275 L/Min maximum flow. Performance complies with EN ISO 9906 Grade 3B tolerances. The 65 mm discharge port connects to standard pipework, and the integrated non-return valve prevents reverse flow when the motor stops.
AISI 316 stainless steel throughout the wetted end ensures 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 55 kg, the unit features microcast stainless steel head and motor support castings. Safety hook holes on the delivery port secure the unit during installation. Liquid temperature tolerance is 60°C, and the pump accepts both C4S and L6W motor options.
