Product Overview
Deep well extraction and mine dewatering require pumps that can handle extreme head demands, and the Lowara ZN612/15-3 delivers 170.1 metres of shut-off head from a 7.5 kW motor. Its 6-inch AISI 316 stainless steel wet end and 142 mm diameter fit standard boreholes while providing exceptional corrosion resistance.
The 415V three-phase motor draws 17 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 water column reversal when the motor stops.
AISI 316 stainless steel construction provides corrosion resistance against aggressive groundwater chemistry. 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 72 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.
