Product Overview
Municipal water supply and agricultural irrigation systems benefit from the Lowara 4ZN612/11-3, a 5.5 kW radial flow pump delivering 124.7 metres of head. Its 6-inch wet end, constructed entirely from AISI 316 stainless steel, provides exceptional corrosion resistance for demanding borehole applications. The compact 142 mm diameter fits standard casings.
The 415V three-phase motor draws 13.7 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 industrial pipework, while the integrated non-return valve prevents water column backflow.
AISI 316 stainless steel across all wetted parts protects against aggressive groundwater chemistry. The suction strainer limits sand ingress to 100 g/m³, while the radial flow impeller includes a removable wear ring for extended service life. The replaceable coupling simplifies maintenance without pump removal.
Weighing 50 kg, the pump includes microcast stainless steel head and motor support components. Safety hook holes on the discharge head allow secure lowering. Maximum liquid temperature is 60°C, and the pump is compatible with both C4S and L6W motor series.
