Product Overview
A 3 kW motor drives the Lowara 4ZN612/6-3 radial flow pump, delivering 68 metres of head for groundwater supply and mine dewatering applications. This 6-inch submersible unit features an all-AISI 316 stainless steel wet end, providing corrosion resistance that extends service life in aggressive borehole conditions. The compact 142 mm diameter fits standard casings while the replaceable coupling simplifies maintenance.
The 415V three-phase motor draws 7.1 Amps and achieves 275 L/Min maximum flow. Hydraulic performance conforms to EN ISO 9906 Grade 3B standards. The 65 mm discharge port connects to standard pipework, and the integrated non-return valve prevents water column backflow during motor shutdown.
Stainless steel radial flow impeller with removable wear ring handles abrasive groundwater, while the suction strainer limits sand ingress to 100 g/m³. AISI 316 construction throughout the wetted end protects against corrosion from aggressive water chemistry, reducing long-term maintenance costs.
Weighing 34 kg, the pump features microcast stainless steel head and motor support components. Safety hook holes on the delivery port facilitate secure installation. Liquid temperature tolerance is 60°C, and the pump supports both C4S and L6W motor configurations.
