Product Overview
Continuous water extraction from deep boreholes is the domain of the Lowara ZN612/16-3, a 9.3 kW radial flow pump delivering 181.5 metres of head. Its all-AISI 316 stainless steel wet end and 6-inch design provide corrosion resistance for demanding groundwater applications, with a 142 mm diameter that fits standard casings.
The 415V three-phase motor draws 20.5 Amps and achieves 275 L/Min maximum flow. Performance meets 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.
All wetted components are AISI 316 stainless steel for corrosion resistance against aggressive groundwater. The suction strainer limits sand ingress to 100 g/m³, while the radial flow impeller includes a removable wear ring. The replaceable coupling simplifies maintenance without pump removal.
Weighing 75 kg, the pump features microcast stainless steel head and motor support castings. Safety hook holes on the discharge head facilitate secure lowering. Liquid temperature tolerance is 35°C, and the unit accepts L6W motor configurations.
