Product Overview
Deep well water extraction and mine dewatering require exceptional head capability, which the Lowara 4ZN612/15-3 provides with its 170.1 metres of shut-off head. This 7.5 kW radial flow pump features all-AISI 316 stainless steel construction and a 6-inch wet end, designed for demanding lift applications where reliability is critical. The 142 mm diameter fits standard boreholes.
The three-phase 415V motor draws 18.7 Amps and delivers 275 L/Min maximum flow. Performance meets EN ISO 9906 Grade 3B tolerances. The 65 mm discharge port accommodates standard piping, while the integrated non-return valve prevents water column backflow.
Corrosion resistance from AISI 316 stainless steel protects against aggressive groundwater chemistry, while the suction strainer limits sand ingress to 100 g/m³. The radial flow impeller includes a removable wear ring for extended service intervals. The replaceable coupling allows component access without full pump removal.
Weighing 58 kg, the pump features microcast stainless steel head and motor support components. Safety hook holes on the discharge head secure the unit during installation. Maximum liquid temperature is 60°C, and the pump is compatible with both C4S and L6W motor configurations.
